The best product for dry skin is the Lactic. Lactic acid works as a humectant, pulling moisture from the air and dermis and holding it in the outer layers of skin. This allows the Lactic acid to gently exfoliate the skin without being drying. Other Benefits: It helps wrinkles by stimulating collagen production. Studies have show after 6-8 weeks of use the thickness of the collagen within the skin is 20-30% greater. This helps to improve the texture of the skin by smoothing fine wrinkles. The Lactic acid is also gentler than the glycolic, which makes it great for people with drier skin. Our Lactic is 50%, which is a stronger version. We would suggest adding some purified water or distilled water to dilute the peel if it is too strong for you.
