Gold-stabilised vitamin C and glycolic acid serum for dramatically brighter, healthier-looking skin. "Most vitamin C loses potency or is hard for skin to absorb. Gold-stabilised, bioavailable Vita-C Complex preserves efficacy for full-strength results every time." Howard Murad, M.D. 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 colours; ideal for all skin tones and skin types, from oily to dry. Results after 1 week: Over 70% saw brighter, healthier skin After 4 weeks: 83% saw brighter, more radiant skin 86% saw healthier skin
