Discoloration Defense is a layerable, daily-use dark spot corrector clinically proven to reduce the appearance of key types of skin discoloration in all skin tones, including hard-to-treat forms such as stubborn brown patches and post-acne marks. This latest-generation formula improves the appearance of skin discoloration, brightens skin, and evens skin tone in as early as 2 weeks.

• 3% Tranexamic Acid - This synthetically-derived ingredient minimizes the recurrence of skin discoloration and stubborn brown patches with continued use.

• 1% Kojic Acid - Naturally produced by certain fungi, kojic acid helps improve skin brightness.

• 5% Niacinamide - Also known as vitamin B3. It has been shown to help reduce the appearance of skin discoloration.

• 5% HEPES - This synthetically-derived acid activates natural enzymes in skin to help break the bonds that bind dead skin cells to the surface for even exfoliation.

Twice daily, apply 3-5 drops of this skin discoloration serum to the face. If using in the morning, apply after a SkinCeuticals vitamin C serum and follow with a broad spectrum sunscreen. Limit sun exposure while using this product. Do not use on irritated or broken skin. If irritation occurs, discontinue use.
