The COSRX Clear Fit Master Patch is an ultra-thin Korean hydrocolloid acne patch that shrinks pimples while staying virtually invisible on the skin. Each of the 18 patches measures just 0.12mm to 0.14mm thick with a matte, gradient-tapered edge, so it blends into the face during daytime wear and sits comfortably under makeup. The hydrocolloid absorbs breakout exudate, calms inflammation and shields the spot from bacteria while it heals.

Why the COSRX Clear Fit Master Patch Works

Hydrocolloid is a medical-grade wound dressing material, and it does the heavy lifting here. Once applied, the patch draws oil, pus and impurities out of the blemish while locking in moisture, creating the moist environment that skin repairs fastest in. It also forms an airtight barrier that blocks bacteria and secondary infection, and stops you touching or picking the spot, which is what usually turns a pimple into a lasting mark.

Ideal For

Suitable for all skin types, including sensitive and acne-prone skin. The Clear Fit patch is the daytime counterpart to the thicker COSRX Acne Pimple Master Patch: reach for Clear Fit when you need discreet coverage at work, at university or under foundation, and use the thicker version for intensive overnight treatment. It works best on surface-level whiteheads and pimples that have come to a head, rather than deep cystic bumps.

• A.D.F. Hydrocolloid Dressing: the core material. An absorbent medical-grade polymer that pulls exudate from the blemish and speeds healing without drying the skin around it.

• Liquid Paraffin: a mineral-oil derived emollient that seals the patch against the skin and prevents moisture loss.

• Cellulose Gum, Styrene Isoprene Styrene Block Copolymer, Polyisobutylene, Petroleum Resin, Polyurethane Film, Tetrakis Methane: the adhesive and ultra-thin film system that creates the airtight seal, the matte finish and the tapered gradient edge.

Free from parabens, sulphates, phthalates, alcohol and added fragrance. Hypoallergenic, dermatologist tested, cruelty free and vegan.

1. Cleanse the area and pat it completely dry. Leftover moisturiser, serum or oil will stop the patch adhering.

2. Peel one patch from the film and press it directly over the blemish, covering it fully.

3. Apply it before the rest of your skincare routine and wear it for up to 8 hours, or overnight.

4. Replace the patch once it turns white and puffy, which means it has absorbed the exudate.

Makeup can be applied gently over the top with a light hand.
