Murad Vita-C Glycolic Brightening Serum 10ml 83% saw a clearer skin with increased radiance after 4 weeks. Boost your radiance with gold-stabilized vitamin C. Pollution and UV light can accelerate skin damage through oxidative stress (free radicals). Vitamin C is a powerful antioxidant that supports healthier skin and can help prevent visible skin damage such as hyperpigmentation, dullness, and uneven tone. Glycolic acid removes dead, dull surface cells to give increased radiance and paves the way for vitamin C to penetrate the skin more effectively. Formulated without fragrance and artificial colors, perfect for all skin tones and skin types.
