Love this product . Using Neostrata products for 12 years and find no other product can improve the clarity like the skin active range . I use this product under matrix support night cream for continued support to the elasticity of my skin . It does what it says it does . Helps with wrinkles, age spots and helps to promote younger looking skin . Have tried other brands but always revert back to this as it has an accumulated effect over time . Now wouldn’t use anything else . Love it ,
