Skin Type: Normal, Dry, Combination, Oily. Skincare Concerns: Dark Spots, Dullness, Loss of Firmness and Elasticity. Formulation: Lightweight Serum.

Highlighted Ingredients: 25% Vitamin C (3-O-Ethyl Ascorbic Acid), a stable, gentle form of vitamin C that visibly evens skin tone and improves firmness.
