COSRX Master Patch Intensive – Acne Patches x36

Discover COSRX Master Patch Intensive, a reinforced and more discreet version of COSRX anti-blemish patches.

Made from hydrocolloid material, these patches create a protective barrier over the pimple. They help to isolate the area from friction, external impurities, and fingers, while gradually absorbing secretions present on the surface of the blemish.

The formula also contains salicylic acid, a BHA commonly used in skincare for blemish-prone skin, as well as tea tree leaf essential oil. COSRX and available INCI lists present these two ingredients as the main active ingredients differentiating the Intensive version from the Basic version.

Their oval shape allows for better coverage of pimples located on curved areas, such as the jawline, chin, or around the nose. The thin, tapered edges improve adhesion while making the patch less visible on the skin.

At Éclat Collagène, we recommend these patches to customers looking for a practical local solution to protect their blemishes and prevent touching them, especially overnight or during the day.

Benefits

• Protects the blemish from friction and impurities.
• Absorbs secretions present on the surface of the pimple.
• Helps prevent touching, scratching, or picking the blemish.
• Contains salicylic acid and tea tree oil.
• Oval shape adapted to facial contours.
• Thinned edges for better adhesion.
• Discreet finish that can be worn under makeup.

For which blemishes?

COSRX Master Patch Intensive are particularly suitable for:

• pimples with a whitehead;
• superficial blemishes;
• pimples that have started to release secretions;
• areas that one tends to touch;
• blemishes located on curved areas of the face;
• pimples requiring protection against friction.

Hydrocolloid patches are generally less effective on deep pimples, microcysts, or blemishes without an opening or visible secretion.

Key ingredients

Hydrocolloid

The hydrocolloid material absorbs liquids present on the surface of the blemish and creates a protective barrier.

When the center of the patch turns white or opaque, it generally indicates that it has absorbed secretions and can be replaced.

Salicylic acid

Salicylic acid is a BHA used in anti-blemish skincare to help exfoliate the skin's surface and improve the appearance of clogged pores. It is present in the composition of Master Patch Intensive.

Tea tree essential oil

Tea tree leaf essential oil is integrated into the formula to support the treatment of blemish-prone areas. It appears in the official ingredient list published by several distributors.

Composition

Cellulose Gum, Hydrogenated Poly(C6-20 Olefin), Polyisobutene, Styrene/Isoprene Copolymer, Salicylic Acid, Melaleuca Alternifolia (Tea Tree) Leaf Oil.

As the composition may change, it is recommended to always check the list on the packaging received.

Instructions for use

Cleanse your face, then thoroughly dry the affected area. The patch should be applied before serums, creams or oils to ensure good adhesion.

Choose the appropriate size, then apply the patch directly to the blemish. Press gently for a few seconds.

Leave it on for several hours or overnight. COSRX generally recommends replacing it when it turns white or opaque after absorbing secretions. A duration of 8 to 12 hours is commonly recommended by the brand.

Gently remove it, clean the area, and apply a new patch if necessary.

Éclat Collagène recommended routine

1. Cleanse skin with a gentle cleanser.
2. Completely dry the blemish.
3. Apply the COSRX Master Patch Intensive.
4. Apply your other skincare products around the patch.
5. Replace it when it turns white, swells, or starts to peel off.

Precautions

External use only.

Do not apply to a deep wound, burn, severe infection, or highly irritated area.

The formula contains salicylic acid and tea tree essential oil. Very sensitive or reactive skin should test the product on a small area before prolonged use.

Discontinue use if redness, itching, or persistent discomfort occurs. In the presence of severe, deep, or painful acne, consult a healthcare professional.

FAQ

How many patches does the pack contain?

The pack contains 36 oval patches, divided into two sizes: 13 × 9 mm and 16 × 11 mm.

What is the difference with COSRX Master Patch Basic?

Master Patch Basic are simple, round hydrocolloid patches. Master Patch Intensive are oval, thinner at the edges, and also contain salicylic acid and tea tree essential oil.

Can they be worn under makeup?

Yes. Their flat shape, thinned edges, and discreet appearance allow them to be worn under makeup. Always apply the patch to clean, dry skin, before foundation.

How long should the patch be left on?

It can be worn for several hours or overnight. COSRX generally recommends a duration of 8 to 12 hours, or replacement as soon as the patch turns white.

Should I pop the pimple before applying the patch?

No. It is not recommended to intentionally pop a blemish. The patches are most effective on pimples that already have a whitehead or a natural opening.

Can I apply a cream under the patch?

No. The skin must be perfectly clean and dry. A cream, oil, or serum can prevent the patch from adhering properly.

Are they suitable for sensitive skin?

They can be suitable for many skin types, but they contain salicylic acid and tea tree essential oil. A preliminary test is recommended for very sensitive skin.

Do these patches definitively treat acne?

No. They offer a local action on superficial blemishes and help prevent their manipulation. They do not treat all causes of acne and do not replace dermatological follow-up.
