Lactic acid is an Alpha Hydroxy Acid that stimulates the production of collagen, natural moisturising factors and supports the integrity of the dermal layer. This peel has a natural hydrating effect on the skin as a result of attracting water molecules to surface skin cells. Enhances skin barrier function and promotes ceramide production. A fantastic treatment for skin ageing, expression lines and superficial wrinkles. Helps brighten dull, lacklustre skin, improves dehydration and couperose skin.

Mandelic acid is an Alpha Hydroxy Acid that is perfect for oily and sebhoreic skins with acneic tendencies.
