Kojic acid is a fungal-derived organic acid that inhibits tyrosinase, reducing melanin production and helping to fade hyperpigmentation, melasma, and dark spots. It is commonly used in topical depigmenting formulations.
Salicylic acid is a lipid-soluble beta-hydroxy acid that exfoliates the skin surface and penetrates sebaceous pores to loosen and dissolve keratin and debris. It is widely used to treat acne, blackheads, and conditions involving thickened or scaly skin.
