COSRX Acne Pimple Master Patches are hydrocolloid patches that effectively treat acne and pimples by creating a protective barrier that absorbs impurities while preventing further infection. These virtually invisible cosrx pimple patches help reduce inflammation and promote faster healing without scarring, making them ideal for both daytime and overnight use. The patches work by absorbing excess sebum and pus from blemishes while shielding them from external bacteria and preventing picking or touching. With easy application and removal, these patches are an essential spot treatment for achieving clearer skin quickly and discreetly. How to use Cleanse and dry your face, then apply the acne patch to your troubled area(s). Choose a pimple patch large enough to cover the spot. Continue with the rest of your skincare routine.
