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.
Retinol is a vitamin A derivative that converts to retinoic acid in the skin, promoting cell turnover and stimulating collagen synthesis. It is widely used to address fine lines, photoaging, and acne.
