Science
Mechanism of Action
Actinidia Deliciosa Fruit extract functions through several key mechanisms: an amino acid-polysaccharide complex enhances the skin's natural moisturizing factor, providing hydration. Fruit acids (AHAs) and enzymes like actinidin offer mild exfoliation, promoting cell turnover and improved skin tone. A rich blend of vitamins (C, E), minerals (potassium, magnesium), flavonoids, and polyphenols delivers significant antioxidant protection against free radicals, environmental aggressors, and UV-induced damage. The extract stimulates collagen synthesis, thereby improving skin elasticity and firmness, while its anti-inflammatory properties and anthocyanin-driven tyrosinase-inhibiting effect work to reduce hyperpigmentation and even skin tone. This combined action reduces melanin, erythema, and sebum while increasing moisture and elasticity.
