Soap - Two Pcs Handmade Kojic Acid Soap Natural Mild Non-irritating Brightening Skin ExfoliatorFace Cleansing Whitening Soap

Kojic acid is a skin-lightening ingredient that decreases hyperpigmentation (dark spots) and evens out skin tone. You can apply it to your face or hands, then rinse it off. Over time, this may fade sun damage, acne scars, and other areas of hyperpigmentation.

Dermatologists often use kojic acid to treat hyperpigmentation. Kojic acid blocks tyrosinase, an enzyme that helps with melanin production. Dark spots form when skin cells have more melanin.

Kojic acid is also an antioxidant, which helps fight free radicals—unstable atoms from sun exposure that can contribute to dark spots.
