COSRX Oval Hydrocolloid Pimple Patches, 90-Count (Medium & Large) — Tea Tree & Salicylic Acid

COSRX Master Patch Intensive are oval hydrocolloid acne patches infused with tea tree oil and salicylic acid to protect blemishes while aiding visible reduction of surface gunk and irritation.

These oval-shaped, skin-toned hydrocolloid patches are designed to stick securely across contours such as jawlines and hairlines, providing a discrete barrier over active pimples. Each patch absorbs fluid, shields the spot from friction and contamination, and includes calming tea tree oil plus salicylic acid to support surface exfoliation. Packaged as a 90-count assortment of medium and large sizes, this set is made for overnight or daytime use when you want coverage that blends into your skin.

How do these patches protect and clean a pimple?

The hydrocolloid layer creates a moist, occlusive environment that draws out fluid and creates a protective seal. As the patch absorbs exudate it turns opaque, signaling that the spot has been isolated and cleaned. The addition of tea tree oil offers a calming aromatic component, while salicylic acid helps to loosen surface debris for easier removal during routine cleansing.

• Hydrocolloid film traps fluids and shields the lesion from dirt and fingers
• Visible color change indicates absorption progress
• Tea tree oil provides a soothing component; salicylic acid helps surface exfoliation
• Designed to be left on for several hours or overnight for best effect

Why choose an oval shape over round patches?

Oval patches are wider along one axis, which helps them lie flat on curved areas like the jawline and hairline without peeling at the edges. The gentle tapering reduces lift at the perimeter so the patch adheres better during sleep or daily activity. That shape also offers slightly more coverage for larger or irregularly shaped breakouts compared with small round dots.

• Better fit on angled skin surfaces compared to circular patches
• Tapered edges minimize lifting and peeling during movement
• Larger surface area covers more of the blemish and surrounding irritated skin
• Easy to position and center over the spot for secure coverage

How should I use Master Patch Intensive for best results?

Start with clean, dry skin and choose a patch that fully covers the affected area. Press the patch edges down firmly so it seals against the skin and leave it in place for several hours or overnight; change patches every 6–8 hours if needed. Replace the patch once it becomes opaque or when it no longer adheres properly, then gently remove and cleanse the area.

• Cleanse and dry skin before application to improve adhesion
• Select medium or large patch to cover the entire blemish plus a margin
• Leave on for multiple hours or overnight; replace when saturated
• Gently remove and follow with your normal skincare routine

Will these patches show on my skin and can I wear them during the day?

Master Patch Intensive is made with a clear matte finish and tapered edges to blend discreetly into many skin tones. While larger patches may be noticeable up close, they are worn comfortably under makeup or alone during the day and are especially useful overnight when you want hands-off protection. For minimal visibility, press the edges flat and choose a size that sits within the bounds of your blemish.

• Clear matte surface reduces shine for a low-profile look
• Tapered edges help the patch lie flush with skin to avoid catching
• Safe to wear under light makeup for daytime concealment
• Designed for both daytime and overnight protection

Who is this for: COSRX Master Patch Intensive is aimed at people who experience occasional or recurring surface blemishes and want a simple, hygienic way to protect and absorb spots while they heal. It’s suitable for those who need coverage that conforms to curved areas like the jawline, prefer a low-visibility option that can be worn during the day, and appreciate the convenience of an unscented-cleansing hydrocolloid combined with supportive ingredients like tea tree oil and salicylic acid. Avoid use on open wounds or mucous membranes; patch testing is recommended for sensitive skin types.
