The key component in most pimple patches is hydrocolloid, a gel-like material that has been widely used in medical wound dressings. Hydrocolloid has a strong ability to absorb exudates (fluids and pus) from wounds or acne lesions, which is why it’s ideal for treating pimples. Once the patch is applied to the skin, it forms a sealed, semi-permeable layer that traps moisture and draws out impurities from within the pore.
Some advanced pimple patches are formulated with additional active ingredients:
Salicylic acid helps exfoliate inside the pores, unclogging sebum and dead skin.
Tea tree oil provides natural antibacterial and anti-inflammatory benefits.
Niacinamide can calm redness and reduce post-inflammatory pigmentation.
Hyaluronic acid provides gentle hydration to prevent the treated area from drying out.
Through this combination of absorption, protection, and active treatment, a Pimple Patch can significantly reduce the size and redness of a pimple overnight or within several hours, depending on its severity.
In recent years, Pimple Patches have become a skincare phenomenon, especially among younger consumers and those who prefer minimalist skincare routines. There are several reasons for their immense popularity:
Ready-to-use and Highly Convenient
Traditional acne treatments require multiple steps—cleansing, applying creams or gels, waiting for absorption, and avoiding contact with clothing or pillows. A Pimple Patch simplifies this process. You can simply clean the area, stick the patch directly onto the pimple, and go about your day or sleep without worrying about smudging or wiping off the product. This makes it particularly attractive for busy people, travelers, or students who don’t want complicated routines.
Hygienic and Hands-free
One of the biggest reasons acne worsens is because we unconsciously touch or pick at pimples, transferring bacteria from our hands to the skin and increasing the risk of infection or scarring. A Pimple Patch serves as a physical shield, preventing direct contact and keeping the area sterile. This can be especially beneficial for teenagers or individuals with the habit of squeezing pimples.
Effective in Reducing Inflammation and Redness
By drawing out excess sebum and pus, the patch reduces the pressure and swelling within the pimple. This helps the skin look less inflamed and irritated after just a few hours. Many users report visible improvement overnight, making these patches a popular “emergency solution” before big events, such as dates, weddings, or photo sessions.
“Invisible” and Makeup-Friendly
Modern Pimple Patches are made of ultra-thin, transparent materials, which can blend seamlessly with the skin. Some are even matte and designed to be worn under makeup, acting as both a healing product and a blemish concealer. This feature is particularly appreciated by people who need to maintain a polished appearance while still treating their skin.
Portable and Travel-Friendly
Pimple Patches usually come in small, compact packages that can easily fit into a purse or travel bag. There is no need to carry bulky skincare bottles or worry about product leakage. Whenever a breakout occurs, you can quickly apply a patch anywhere—whether you’re at work, on a plane, or in a hotel.
Gentle on Skin
Compared to some harsh acne treatments that may cause dryness, peeling, or irritation (especially benzoyl peroxide or retinoid-based products), Pimple Patches are non-invasive and mild. Most products are free of alcohol and fragrance, making them suitable for sensitive or reactive skin.
Key Features:
Made from medical-grade hydrocolloid, which is highly absorbent and creates a moist healing environment.
Primarily focuses on drawing out pus, oil, and impurities from the surface of the skin.
Often comes in transparent or semi-transparent designs, making it less noticeable on the skin.
Best For:
Whiteheads or pimples that are close to the surface and have visible pus heads.
Post-extraction healing, where the patch can absorb remaining fluids and protect the wound from bacteria.
Advantages:
Drug-free and gentle, suitable for sensitive skin.
Reduces redness and swelling without over-drying the skin.
Prevents scabs and scars by maintaining optimal skin hydration.
Example Usage Scenario:
You notice a small whitehead forming on your chin. Instead of popping it, you clean the area, apply a classic hydrocolloid patch, and leave it overnight. By morning, the patch turns white, indicating it has absorbed the impurities, leaving the area cleaner and less inflamed.
Key Features:
Contain active acne-fighting ingredients such as salicylic acid, tea tree oil, or niacinamide.
Not only absorb pus but also exfoliate inside pores, fight bacteria, and calm inflammation.
Best For:
Red, inflamed pimples that require more than just fluid absorption.
Early-stage acne where prevention of bacterial growth is critical.
Advantages:
Accelerates healing by combining physical protection with chemical treatment.
May reduce the risk of post-inflammatory marks due to anti-inflammatory components.
Precautions:
Some medicated patches can be too strong for sensitive skin, so patch testing is recommended.
Not suitable for broken skin or open wounds unless designed for wound healing.
Example Usage Scenario:
If you have a painful, red pimple on your forehead, a medicated patch with salicylic acid can help penetrate pores to unclog sebum while also preventing the pimple from becoming larger overnight.
Key Features:
Advanced patches with tiny, dissolving micro-darts or microneedles (much thinner than human hair).
These micro-darts painlessly penetrate the skin’s surface and deliver active ingredients like hyaluronic acid, niacinamide, or peptides deeper into the epidermis.
Best For:
Cystic or deep-rooted acne that cannot be reached by standard hydrocolloid patches.
Stubborn pimples that remain under the skin for several days.
Advantages:
Delivers active treatment directly into the lesion, bypassing the skin’s natural barrier.
Can flatten cystic pimples faster compared to topical creams.
Considerations:
Usually more expensive due to advanced technology.
Best used as an occasional “emergency fix” rather than a daily routine.
Example Usage Scenario:
If you feel a painful bump under your skin (a cystic pimple forming), applying a micro-needle patch at night can inject active ingredients directly into the area, reducing swelling and pain by the next morning.
Key Features:
Daytime Patches: Ultra-thin, matte finish, and almost invisible, designed to be worn under makeup without being noticed.
Nighttime Patches: Thicker, more absorbent, and designed for overnight healing, often larger to cover multiple spots.
Best For:
Daytime: People who want to treat acne discreetly while at work, school, or social events.
Nighttime: Deep or inflamed pimples that need intensive overnight treatment.
Advantages:
Flexible use depending on your schedule and acne condition.
Day patches can also act as a “barrier layer” under makeup, preventing foundation from irritating the pimple.
Example Usage Scenario:
In the morning, you apply a thin, invisible patch under your foundation to keep a pimple protected all day. At night, you switch to a thicker patch that absorbs oil and pus while you sleep.
The foundation of most acne patches is hydrocolloid or hydrogel technology, which was originally developed for medical wound dressings. Hydrocolloids are made of gel-forming agents like gelatin, pectin, or carboxymethylcellulose, combined with a flexible, semi-occlusive outer layer. When the patch is applied to acne, the hydrocolloid acts like a sponge, absorbing excess pus, oil (sebum), and fluid exudates from the pimple.
The “White Bulge” Effect:
As the hydrogel absorbs impurities, the patch gradually turns white and opaque—a visible indicator that it is working. This change in color is due to the swelling of the hydrogel matrix as it fills with fluid. The process not only draws out trapped pus but also flattens the pimple by reducing internal pressure.
Gentle Extraction vs. Popping:
Unlike manual squeezing, which can rupture the skin barrier and lead to scarring, hydrogel extraction is non-invasive. It works passively over several hours, providing a safer and cleaner way to remove impurities without damaging surrounding tissue.
Maintaining Skin Integrity:
The absorbed material stays locked inside the patch, preventing recontamination of the area. This controlled absorption helps keep the wound clean while allowing the skin to heal under optimal conditions.
Acne patches serve as a physical shield, effectively isolating the blemish from harmful external elements. This function is critical for preventing secondary infections and promoting faster recovery.
Isolation from Bacteria and Dust:
Pimples are particularly vulnerable to environmental irritants such as dust, sweat, or airborne pollutants. The patch creates a micro-environment that blocks these contaminants, reducing the chance of the acne worsening.
Prevention of Hand Contact:
One of the main reasons acne scars form is due to unconscious touching or picking. Our hands carry bacteria and oils that can aggravate pimples, making them more inflamed or even infected. The patch acts like a "second skin," ensuring that the affected area is protected from accidental scratching or pressing.
Barrier Against Makeup or Skincare Products:
Many people continue to wear makeup even when they have breakouts. Makeup products can clog pores or irritate inflamed areas. A pimple patch not only covers the pimple but also prevents foundation or powders from seeping into the wound, making it safer to apply cosmetics.
One of the lesser-known but highly effective principles of acne patches is that they promote a moist wound healing environment. This is a dermatological technique commonly used for treating wounds, burns, and surgical scars.
Why Moist Healing Matters:
When a wound is exposed to air and dries out, it forms a scab. While scabs are a natural part of healing, they can slow down skin regeneration and increase the risk of post-inflammatory hyperpigmentation (PIH)—commonly seen as dark spots after acne.
In contrast, a moist environment keeps skin cells hydrated and active, accelerating tissue regeneration and reducing the chance of scarring.
Skin Barrier Recovery:
Hydrocolloid patches prevent the loss of natural moisture, maintaining an ideal humidity level for healing. This also helps minimize flaking or dryness around the pimple, which often occurs when using traditional drying treatments like benzoyl peroxide.
Reduced Pain and Irritation:
A moist environment reduces the friction between the damaged skin and the external environment, helping the pimple heal without additional redness or irritation.
Some modern acne patches go beyond passive absorption and incorporate targeted active ingredients that work synergistically with the hydrocolloid base to fight acne at the root.
Salicylic Acid:
A beta-hydroxy acid (BHA) known for its ability to penetrate deep into pores and dissolve excess sebum. Salicylic acid in acne patches helps to unclog pores while reducing inflammation, making it ideal for treating active, red pimples.
Tea Tree Oil:
A natural essential oil with antibacterial and anti-inflammatory properties. It works by neutralizing acne-causing bacteria (Propionibacterium acnes) while calming redness and swelling.
Niacinamide:
A form of vitamin B3 that strengthens the skin barrier, reduces redness, and supports healing. Niacinamide can also help fade post-acne marks over time.
Hyaluronic Acid:
Some patches include hydrating agents like hyaluronic acid to prevent excessive dryness around the affected area, ensuring that the healing process doesn’t compromise skin softness.
Centella Asiatica Extract (Cica):
Known for its wound-healing and soothing effects, Cica is often added to reduce inflammation and support skin regeneration.
The true effectiveness of an acne patch comes from the synergy of these four principles:
Absorption: The hydrogel draws out pus, oil, and debris.
Protection: The patch shields the area from bacteria, dirt, and irritation.
Healing Environment: By maintaining moisture, it speeds up the skin’s natural repair cycle.
Targeted Treatment: Active ingredients reduce inflammation and accelerate healing at the molecular level.
One of the most immediate and noticeable effects of a pimple patch is its ability to calm redness and inflammation around the blemish. This is largely due to the hydrocolloid material, which not only absorbs the pus and oil inside the pimple but also creates an environment that allows the skin to recover naturally.
Absorbing Excess Fluids:
Pimples often contain a mix of sebum, pus, and dead skin cells that cause swelling and redness. The patch draws out these fluids in a controlled manner, relieving internal pressure and flattening the pimple.
For instance, after wearing a patch overnight, many users notice a visible reduction in swelling and a much calmer skin tone in the affected area.
Soothing Inflammation:
Some patches are enhanced with anti-inflammatory ingredients like tea tree oil or centella asiatica extract, which help reduce redness even faster. This makes them a perfect emergency solution for sudden breakouts, especially before important events.
Preventing Fluid Spread:
When a pimple ruptures on its own, the pus can spread to nearby pores, causing new breakouts. Pimple patches effectively lock the fluid inside, preventing cross-contamination.
Unconscious pimple picking is one of the leading causes of acne scarring and post-inflammatory hyperpigmentation. Many people find it hard to resist touching their face or popping a pimple, even though this habit often makes the situation worse.
Pimple patches act as a protective barrier, helping to break this habit in several ways:
Blocking Hand Contact:
The patch covers the pimple entirely, making it physically impossible to pick or squeeze the affected area. This not only prevents scarring but also reduces the risk of introducing bacteria from the fingers into the wound.
Reducing Psychological Urge:
Since the pimple is covered, it becomes less visible and less tempting to touch. This is especially useful for people who have a tendency to constantly check or press their breakouts.
Maintaining Hygiene:
By preventing direct contact with the pimple, the patch minimizes external irritation from environmental bacteria, dirty pillowcases, or even makeup brushes.
The healing of acne is not just about removing the pus; it involves reducing inflammation, regenerating the skin barrier, and preventing scar formation. Pimple patches accelerate this entire process.
Hydrogel Healing Environment:
As mentioned in the previous section, the hydrogel layer maintains a moist healing environment, which has been scientifically proven to speed up cell regeneration and prevent the formation of hard scabs.
This is particularly important for people with sensitive skin, as traditional drying treatments (like benzoyl peroxide or sulfur-based creams) can leave the skin flaky and irritated, delaying healing.
Reduced Secondary Damage:
Without a patch, acne wounds are often exposed to friction from clothing, pillowcases, or even accidental scratching during sleep. By acting as a soft cushion, the patch shields the wound from external pressure, allowing uninterrupted healing.
Faster Recovery Timeline:
Many users report that using a pimple patch can shorten the recovery time of a pimple by 1–2 days compared to leaving it untreated. This is because the patch both extracts impurities and creates optimal conditions for the skin to rebuild itself.
In addition to its treatment benefits, many modern pimple patches have evolved to offer cosmetic advantages, making them “invisible protectors” that can be worn during the day.
Thin and Transparent Design:
Daytime pimple patches are often ultra-thin, with a matte finish, which allows them to blend seamlessly with the skin. They are barely noticeable, even in close-up situations, making them ideal for wearing to work, school, or social gatherings.
Makeup-Friendly:
Certain brands have designed patches that work as a primer for foundation. You can apply makeup on top of them without worrying about clogging the pores or aggravating the pimple. The patch acts as a protective barrier between the skin and makeup, ensuring that the healing process continues uninterrupted.
Confidence Booster:
Acne can often make people self-conscious, but knowing that a pimple is both protected and camouflaged can boost confidence throughout the day. This dual function—treatment plus concealment—makes pimple patches stand out from traditional topical treatments.
While the four main benefits are the core reasons why pimple patches are effective, there are additional advantages worth mentioning:
Reduced Risk of Hyperpigmentation:
By preventing picking and scabbing, patches help avoid the dark spots that often remain after acne heals.
On-the-Go Treatment:
Unlike creams or gels that require time to dry, pimple patches are mess-free and can be applied anytime, anywhere.
Targeted Treatment:
The patch delivers all its benefits directly to the problem area, unlike some topical treatments that can spread to unaffected skin and cause dryness or irritation.
Gentle Yet Effective:
Because they rely on physical rather than aggressive chemical action, pimple patches are safe for sensitive or combination skin and can be used alongside other skincare steps.
Cleaning is the first and most critical step before using the acne patch.
If there is oil, dust or skin care product ingredients on the skin surface, the adsorption and sealing of the acne patch will be greatly reduced.
Choose a mild cleanser:
It is recommended to use a weak acid cleanser with a pH value close to the skin, and avoid cleansers containing too many soap bases or highly irritating ingredients, because these will over-degrease, cause the acne area to dry out and even damage the skin barrier.
When cleaning, wet your face with warm water, add a small amount of cleansing foam, and gently massage with your fingertips, especially around the acne, avoid rubbing hard.
Keep your skin dry:
Before using the acne patch, be sure to pat your face with a clean towel or tissue to keep the acne area completely dry. Because if there is moisture or skin care product residue, it will reduce the adhesion of the acne patch and make it easy to fall off.
Avoid applying heavy skincare products first:
Before applying the acne patch, it is not recommended to apply heavy creams, oils or sunscreen products first, because these oils will prevent the acne patch from fitting the skin. If skincare products must be used, the acne patch should be applied to the acne first, and then subsequent care should be performed on other areas.
The size of the acne patch is not "the bigger the better" or "the smaller the more delicate". The correct choice is to ensure that the acne patch can cover the acne and the surrounding 1-2 mm area according to the size of the acne.
Why cover 1-2 mm more?
Because the inflammation of acne is not limited to the visible red and swollen part, there may also be tiny wounds or invisible inflammation on the surrounding skin. Covering a slightly larger area can provide more complete isolation and protection to avoid bacterial infection or secondary contamination.
How to judge whether the size is appropriate?
If the acne patch cannot completely cover the acne after application, or the edge is just stuck on the edge of the acne and easily lifts up, it means that the patch is too small.
On the contrary, if the acne patch covers too large an area, it will also look unnatural, especially when applying makeup during the day.
Choose according to the type of acne:
For pustules that have already whitened, choose a slightly larger patch to ensure adsorption.
For smaller red and swollen acnes or unbroken acnes, use a small patch for point-to-point care.
When removing the acne patch, be sure to keep your hands clean. It is best to use clean tweezers or washed fingers to avoid contact with the adhesive surface of the patch.
Press gently to fit:
After placing the acne patch on the acne, press gently with your fingertips for about 10-15 seconds to help it fit completely with the skin.
When fitting, avoid using your fingernails to pick or repeatedly adjust it, as this will reduce the adsorption capacity of the patch.
Avoid bubbles or wrinkles:
If there are bubbles when fitting, it will affect adsorption and isolation. The correct way is to gently press from the center outward to allow the patch to fit completely with the skin.
An acne patch that does not fit well not only has poor absorption effect, but may also fall off more easily due to the warping of the edges.
Pay attention to the placement of the patch:
If the acne is on the nose, chin or other curved parts, the patch may not be easy to stick firmly. In this case, you can choose a softer patch, or cut a larger patch into a suitable shape to ensure its fit.
The longer the acne patch is applied, the better. Its adsorption capacity is limited. When it absorbs enough pus and oil, it will turn "white" or bulge, and it needs to be replaced in time.
Why 4-8 hours?
The active adsorption cycle of most acne patches is between 4-8 hours. After this time, the patch may be saturated and no longer have effective absorption function. It may even lose its stickiness due to long-term exposure to oil.
Therefore, it is recommended to use it for 4-6 hours during the day, and leave it overnight (about 6-8 hours) at night and replace it the next morning.
When does it need to be replaced immediately?
The surface of the patch is obviously white or bulging.
The edge of the patch is warped or soaked with sweat or oil.
In special circumstances (such as after sweating during exercise), it is recommended to replace it in advance.
Do not tear it off frequently to check:
Many people can't help but lift up the acne patch to check the absorption, which will destroy the sealing effect of the patch and may also bring in new bacteria. The correct way is to wait patiently until the replacement period.
After the acne patch is removed, the acne area will be in a relatively clean and fragile state. The care method at this time will directly affect the quality of acne recovery in the later stage.
Gently clean the residue:
After removing the acne patch, you can gently rinse the acne area with warm water to remove any residual gelatin and avoid clogging the pores.
Avoid immediate makeup or high-irritation care:
Because the acne area is still in a state of repair, it is not recommended to immediately apply products containing alcohol, acid or high-concentration active ingredients. It is also best to avoid applying makeup immediately, otherwise it will increase the burden on the pores.
Moderate moisturizing and soothing:
After removing the acne patch, you can use a non-irritating moisturizing spray or light moisturizing lotion to help maintain the repair ability of the skin barrier. If there is a slight red mark on the acne site, you can use a product with repair ingredients (such as Centella asiatica, panthenol) in the subsequent skin care.
Even though the use of acne patches is relatively simple, many people use them improperly, which reduces the effect. Here are some common mistakes:
Error: Applying directly to the face without cleaning it
Correct method: Make sure to cleanse the skin thoroughly and keep it dry.
Error: Applying after applying makeup or sunscreen
Correct method: The acne patch must be applied before skin care or makeup.
Error: Applying it for too long, or even for a day
Correct method: Follow the 4-8 hour principle and replace the patch with a new one after saturation.
Error: Pressing or lifting it frequently with your hands
Correct method: Do not touch it repeatedly after applying it to avoid bacterial contamination.
Acne patches are originally designed to absorb and isolate small-scale acne or pustules. They are not suitable for large wounds or severely suppurated wounds.
Why can't they be applied to large wounds?
The main material of acne patches is hydrogel or hydrocolloid, which has limited adsorption capacity. If the acne is large or deep suppuration has occurred, the absorption function of the acne patch alone cannot effectively clean the pus. Instead, it may cause the wound to be deprived of oxygen due to the closed environment, increasing the risk of bacterial growth.
What to do with severely infected acne?
For cystic acne with severe redness, swelling, and obvious pain, it is best not to blindly use acne patches, but to perform anti-inflammatory care first and consult a doctor if necessary. This type of acne often requires oral or topical anti-inflammatory drugs, and the sealing of acne patches sometimes increases skin pressure.
Wrong case:
Some people will directly apply acne patches to large wounds that have just been squeezed. As a result, not only does it not help the wound heal, but it also delays healing and even worsens the infection due to insufficient breathability.
The effect of acne patches is "auxiliary" rather than a fundamental treatment. It mainly helps acne recover faster by absorbing pus, isolating external stimuli, and reducing redness and swelling, but it cannot solve the acne problem from the source.
The root cause of acne:
Acne is often related to multiple factors such as excessive sebum secretion, clogged pores, bacterial infection, and imbalanced hormone levels. If you want to completely improve it, you must make comprehensive adjustments in terms of lifestyle, diet, skin cleansing, work and rest, and skin care product selection.
Acne patches can only solve "surface problems":
Acne patches are more suitable for pustular acne with whiteheads or superficial acne, which accelerates recovery by absorbing pus and oil. For deep cystic acne or closed comedones, acne patches have limited effect and cannot "pull out" deep inflammation.
Correct attitude:
Acne patches should be regarded as emergency care products, such as when going out for a date, going to work, or when you need to quickly improve your appearance, but not as a long-term acne treatment solution.
Some people like to tear off acne patches to check their absorption, or change patches frequently, thinking that this is more "clean". But this practice actually aggravates the irritation of acne.
Why is frequent tearing bad?
Every time you tear off the acne patch, it will cause a certain amount of pulling on the skin around the acne, especially the epidermis of the acne wound that has just healed is very fragile. Frequent pulling not only easily damages the skin barrier, but may also cause the redness to worsen and the recovery time to prolong.
Correct approach:
Once the acne patch is applied, keep it on the skin for 4-8 hours and do not open it casually. Wait until the acne patch turns white, bulges, or the edge of the patch lifts before replacing it.
A little tip:
If you are worried that the patch will be accidentally rubbed off while sleeping, you can gently press and fix the acne patch around the edges before going to bed to ensure that it fits firmly, rather than getting up in the middle of the night to repeatedly adjust it.
The materials and ingredients of acne patches vary greatly among different brands, especially those containing active pharmaceutical ingredients. People with sensitive skin and pregnant women should pay special attention.
Pure hydrogel vs. medicated acne patches:
Pure hydrogel acne patches: The main ingredient is hydrocolloid, which does not contain any pharmaceutical ingredients. Its main function is to absorb pus and isolate external stimuli. It is safe for most skin types.
Medicated acne patches: Some will add ingredients such as salicylic acid, tea tree essential oil, and azelaic acid. These ingredients have anti-inflammatory, keratin-dissolving, and antibacterial effects, but may have irritation risks for pregnant women or sensitive skin.
Pregnant women should note:
During pregnancy, the skin is more sensitive, and some ingredients (such as high concentration of salicylic acid) are not suitable for use. Therefore, when choosing acne patches, pregnant women should choose pure hydrogel and drug-free ones, and consult a doctor if necessary.
Selection criteria for sensitive skin:
If you have sensitive skin, it is recommended to do a small area test behind the ear or on the jaw to confirm that there is no allergic reaction before applying it on the face. And try to choose acne patches with low-sensitivity formula, fragrance-free, and alcohol-free.
Acne patches cannot replace daily cleansing and skin care:
Some people ignore cleansing and skin care after applying acne patches, thinking that acne will not worsen. In fact, if the overall oil secretion on the face is strong, gentle cleansing is still required, and acne patches are only a local care method.
Don't apply acne patches after makeup:
Many people will apply acne patches after makeup to "cover blemishes", which will reduce the adhesion of the patch. The correct way is to apply acne patches first and then apply foundation, and use a light foundation suitable for acne patches.
It is not recommended to apply the patch to cystic acne that has not yet broken:
Cystic acne is generally located in the deeper layer of the skin, and it is difficult for the acne patch to absorb the inflammatory substances inside. If this type of acne is obviously painful, you can first use anti-inflammatory soothing products (such as ice packs, repair essences) instead of relying solely on acne patches.
Avoid applying the patch to extremely dry or flaking skin:
If the skin around the acne is cracked or peeling, applying the acne patch will pull the skin and aggravate the damage. At this time, you should strengthen moisturizing and repair care before considering using the acne patch.
Myth 1: Acne patches can make acne disappear overnight
Fact: The function of acne patches is to shorten the recovery time of acne, but it is not a magic that can "heal instantly". For severe acne, it needs to be replaced several times to see obvious results.
Myth 2: The longer the acne patch is applied, the better the effect
Fact: Applying the patch for too long will only make the acne patch ineffective after it is saturated with adsorption, and it may also breed bacteria. 4-8 hours is the best cycle
Myth 3: You don’t need to pay attention to hygiene when using acne patches
Fact: Even if you use acne patches to isolate, you can’t touch your face with your hands, and you can’t use unclean tools to squeeze acne, otherwise it will still be infected again.
Myth 4: Acne patches are equivalent to acne removal drugs
Fact: Acne patches are just a "physical care product" and do not directly change the mechanism of acne formation, nor can they replace professional acne treatment.
