Pollution and UV radiation can accelerate skin damage through oxidative (free radical) stress. Vitamin C is a powerful antioxidant that promotes healthier-looking skin and helps prevent visible skin damage, such as discoloration, dullness, and uneven skin tone. Glycolic acid quickly works on the surface, removing dead, dull skin cells to reveal more radiant skin and allowing vitamin C to reach deeper layers of the epidermis. The fragrance- and color-free formula is ideal for all skin tones and types. How to use: Massage Vita-C Glycolis Serum into your face, neck and décolleté, then apply a moisturizing cream.
