A spot acne treatment designed to shrink and heal active acne, pimples, whiteheads and blackheads. Cosrx Clear Fit Mast Patches are made to treat breakouts by eliminating infection and bacteria. The patches breakdown debris from blackheads and absorb oil and waste from whiteheads, while protecting the skin from external pollutants. Slightly thinner and shaped a bit more discreet than the Master Acne Patches, the Clear Fit Patches are perfect for daytime wear under makeup.
