COSRX Master Patch Intensive 90 Patches

• Active breakouts

COSRX Master Patch Intensive delivers 90 hydrocolloid patches for intensive, on-the-spot blemish treatment. Each patch draws out pus and excess sebum while creating a protective barrier that prevents picking and bacteria from making things worse. The result: visibly flatter, calmer blemishes — often within a single overnight application. With three patch sizes included, they’re easy to apply precisely over any sized blemish. Thin, flexible, and discreet enough for daytime wear too.

Cleanse and thoroughly dry skin. Peel off one patch and apply firmly and directly over a blemish or pimple. Leave on for a minimum of 6–8 hours or overnight for best results. Peel off gently and discard. Repeat as needed until the blemish has healed.

The ingredients listed are accurate at the time of publication. However, formulations may be updated or adjusted at the brand’s discretion to improve efficacy or maintain quality standards. Please refer to the product packaging for the most up-to-date ingredient list.

Key Ingredients: Hydrocolloid (Carboxymethylcellulose Sodium, Polyisobutylene, Polyurethane Film).

For external use only. Avoid direct contact with eyes, and if contact occurs, rinse thoroughly with water. Discontinue use if irritation or rash develops, and consult a physician if necessary. Keep out of reach of children and store in a cool, dry place away from direct sunlight. As with any skincare product, we recommend performing a patch test prior to full application to ensure compatibility with your skin.
