Ascorbic C15

Ascorbic C15

Ascorbic C15 is a next-generation illuminating anti-aging serum that combines 15% L-ascorbic acid (pure vitamin C), 5% glutathione, and 1% green tea extract, formulated to combat the key signs of skin aging. This powerful antioxidant trio fights oxidative stress, evens out skin tone, enhances radiance, and smooths expression wrinkles.

From a molecular perspective, L-ascorbic acid, at concentrations between 8% and 20% and a pH below 3.5, effectively penetrates the epidermis, stimulating collagen synthesis, inhibiting tyrosinase, and strengthening the skin barrier. Its notable instability is reduced by an acidic pH (3.03.2) and complementary antioxidants; glutathione restores active forms of oxidized vitamin C, while green tea soothes and boosts antioxidant defense.

Regarding formulation, Ascorbic C15 offers a fast-absorbing watery texture. Due to the inherent instability of pure ascorbic acid, the open-use period (PAO) is only 3 months. It is recommended to keep it refrigerated, below 5 C.
