Skin discoloration is the result of excess melanin, a natural pigment that gives color to skin, often triggered by chronic UV exposure, hormonal fluctuations, post acne blemishes, heat or trauma to the skin, and natural aging. This anti-discoloration duo features Phloretin CF® With Ferulic Acid, a patented daytime vitamin C antioxidant face serum that delivers advanced environmental protection and diminishes the appearance of fine lines and discoloration, layered with Discoloration Defense, a daily-use dark spot corrector clinically proven to reduce the appearance of key types of skin discoloration, including hard-to-treat forms such as stubborn brown patches and post-acne marks. This pairing will improve the appearance of uneven skin tone and overall skin radiance.
