This potent serum from The Ordinary targets signs of aging using a stable derivative of Vitamin C, Ascorbyl Glucoside, stabilized at a concentration of 12%. Ascorbyl Glucoside is known for its antioxidant properties, helping to brighten the complexion and address uneven skin tone over time. It integrates seamlessly into your existing skincare routine, working to promote a more radiant and youthful appearance. Apply a few drops to the face in the morning and/or evening before heavier creams. As effectiveness may vary based on skin type, patch testing before regular use is recommended.
