In Kristals Cosmetics' AVENTURINE Collagen Booster Mask, a hydrotensyl complex (hydrolyzed collagen and elastin) works to form a protective barrier that helps skin retain moisture while smoothing and softening. It’s enhanced with kaolin clay, used for centuries by Romans, Greeks and Egyptians to purify and balance dry and oily skin. Kaolin clay helps mineralize dry areas while removing excess sebum from oily areas to give you smooth skin that retains moisture. To this, we added zinc oxide, an anti-inflammatory that reduces skin irritation and inflammation, along with menthyl lactate for a long-lasting cooling effect. This rich formula helps to seal in moisture in the skin.
