AC Collection Blemish Care Sheet Mask

COSRX AC Collection Blemish Care Sheet Mask is a single-use mask aimed at skin that has been through a breakout and is now dealing with the aftermath. COSRX formulates it with tea tree extracts and ectoin, and builds the sheet itself in three layers.

What it actually does

• Works on the marks left behind. COSRX positions this mask around fading the traces acne leaves on the skin, not just the spot itself.
• Calms active blemishes. The brand lists calming blemishes and refreshing the skin among its stated benefits.
• Addresses uneven tone. COSRX describes it as effective on hyperpigmentation — the kind of patchiness that lingers after a spot has gone.
• Three-layer sheet. The mask uses a special three-layer construction, which the brand credits for how well it delivers hydration.
• Tea tree and ectoin. These are the two ingredients COSRX names for this mask — nothing else is claimed.

How to use

1. Smooth the sheet over clean skin so it sits flat against the face.
2. Leave it on for 15 to 20 minutes.
3. Peel it off and tap the leftover essence into the skin with your fingertips.
4. External use only — keep it away from the eyes.

Questions

How often can I use it?

Each pack is a single mask, so it works as an occasional step rather than a daily one. Many people slot a mask like this in once or twice a week, after cleansing and before their cream.

Do I rinse my face afterwards?

No. Remove the sheet and pat what is left on the skin until it absorbs, then continue with the rest of your routine.

Can I use it while I have an active spot?

COSRX lists calming blemishes as one of its benefits, so it is intended for skin that is actively dealing with them. If the spot is open or broken, let it close first.
