Our facial treatment patches contain niacinamide, vitamin C, and licorice root extract. They target the source of dark spots, brighten skin tone, and help fade dark spots. They are easy to use: Cleanse and dry your face. Peel off the protective film, remove a patch from the edge, and align it with the dark spot area on your skin. Gently press and smooth to secure it. It is recommended to remove the patch after 8 hours. It helps improve dark spots and soothes the skin.
