Science
Mechanism of Action
This extract functions as a mild exfoliant, primarily due to its citric acid content, an AHA, which aids in the removal of dead skin cells and improves skin texture. Its Vitamin C and flavonoid components provide significant antioxidant protection against free radical damage. As a natural astringent, it minimizes the appearance of pores and helps regulate sebum production. Additionally, it offers clarifying, deep cleansing, and antibacterial benefits, potentially inhibiting tyrosinase for skin brightening and stimulating cellular regeneration and collagen synthesis.
