The age-defying Define serum restores healthy smoothness to dry skin. Its multifunctional formula with AHA acids exfoliates the skin, evening out its texture, reducing the appearance of wrinkles, and minimizing imperfections. Soothing botanical components improve the skin's appearance without stripping away precious moisture or causing irritation, while the 2% AGP Retinol complex (0.25% pure retinol) penetrates through several layers of skin for optimal results. Wrinkles are reduced, and skin tone is evened out.
