COSRX acne patches: 24-count Original vs 18-count Clear Fit in five steps

Compare two Korean COSRX patch formats and see when to apply a hydrocolloid patch before skincare or makeup.

Official 2022 COSRX Acne Pimple Master Patch brand film; not a current efficacy test · COSRX Korea official · YouTube

COSRX's Korean store currently lists Acne Pimple Master Patch (24 patches) and Clear Fit Master Patch (18 patches) separately. The original 24-count pack contains ten 7 mm, five 10 mm and nine 12 mm patches. COSRX markets the thin Clear Fit version as less conspicuous for daytime wear under makeup; visibility varies. Korea's quasi-drug classification and label details should not be assumed to apply to products sold in other countries. Official COSRX YouTube posts from 2017 and 2022 provide historical brand visuals only, not tests of today's exact formulas, packages or outcomes. You need not buy both formats.

    Compare Korean names, counts and sizes

    The 24-pack contains 10 patches of 7 mm, five of 10 mm and nine of 12 mm. The Korean Clear Fit 18-pack shows a single 10 mm size. Its thin finish for daytime use is a brand-described feature, not an independently measured guarantee. Older videos may show older packs.

    Clean the spot gently and dry it fully

    Wash your hands, cleanse the area gently and let it dry. COSRX advises attaching patches before skincare on a clean, dry surface. Applying over cream or foundation may weaken adhesion.

    Place one appropriately sized patch

    With the original 24-pack, select a patch slightly wider than the spot, peel it carefully and apply gently. Apply Clear Fit similarly without stretching the skin. Do not squeeze or pop a pimple to make a patch work. The 2022 official brand film is a product reference, not our clinical test.

    Continue skincare and makeup around the patch

    After the patch adheres, use the rest of your gentle routine as directed. COSRX describes Clear Fit as suitable under makeup, but avoid rubbing it hard or layering irritating products beneath it. Exposed skin still needs sunscreen.

    Watch for irritation and replace as directed

    Korean instructions for the original patch advise replacement when absorbed fluid turns it white and swollen. Peel off slowly. Stop if adhesive irritation occurs. Deeper painful nodules or cysts, spreading redness or persistent acne require medical assessment rather than relying on a patch.

✦ Helpful tips

  • Choose the multi-size 24-count format for size flexibility or compare Clear Fit's thinner 18-count format for daytime discretion, without assuming guaranteed results.
  • Check the actual local packaging: Korean quasi-drug classification and ingredients, availability and claims may differ in other markets.

ⓘ Keep in mind

  • Remove the patch and stop if itching, rash, redness or adhesive sensitivity develops; seek care for severe pain or possible infection.
  • Hydrocolloid patches do not treat every type of acne or prevent future breakouts. Avoid squeezing pimples.
