Brightening serum, 30 ml Pollution and UV light can accelerate skin damage through oxidative (free radical) stress. Vitamin C is a potent antioxidant that supports healthier-looking skin and can help prevent visible skin damage like hyperpigmentation, dullness and uneven tone. Glycolic acid rapidly resurfaces and removes dead, dulling surface cells to reveal more radiant skin, and clears the way for vitamin C to penetrate skin more effectively. Formulated without fragrance and artificial colors; ideal for all skin tones and skin types, from oily to dry.
