HOME COSRX AC Collection Blemish Care Sheet Mask

Do you suffer from acne, blemishes and skin inflammation? Give your skin a well-deserved break - with the COSRX AC Collection Blemish Care Sheet Mask.

This uniquely formulated mask is designed to soothe stressed skin while also helping to lighten dark and reddened acne scars. High-quality plant ingredients soothe, brighten and moisturize the skin, while the 3-layer mask made from natural cellulose helps to transport the active ingredients deep into the skin layers. The gel-like biocellulose material fits tightly to the face, creating a seal and acting like a second skin. 

  • Tea tree leaf extract 9,000ppm has great antimicrobial properties to calm redness, swelling and inflammation.
  • Niacinamide supports the skin barrier, increases its resiliency, and improves the texture by making the pores look smaller.
  • Ectoin is a natural amino acid derivative that protects against pollution induced skin aging.
  • Allantoin is a non-irritating ingredient that soothes and protects the skin.

Suitable for all skin types, in particular for acne-prone and sensitive skin.
