A multifunctional Alpha Hydroxy Acid that works to reduce redness and inflammation caused by acne and rosacea. Improve the appearance of fine lines, melasma, and sun-related pigmentation. Mandelic Acid is an effective 5-Alpha Reductase inhibitor. 5-Alpha Reductase is an enzyme that converts testosterone to DHT (dihydrotestosterone), a more potent testosterone derivative that promotes sebaceous gland activity. As the sebaceous glands become more active, sebum and acne lesions may increase. For external use only. Keep out of reach of children. There are three concentrations for your best needs.
