The superstar ingredient in Sunday Riley’s ‘Good Genes’ is lactic acid. Lactic acid is an alpha hydroxy acid (AHA), which exfoliates the skin by breaking down the glue that keeps dead skin together - therefore allowing it to shed. This process allows for improved skin tone and texture and a reduction in the appearance of fine lines and winkles. (Read more about AHAs here).
Personally, I found Good Genes to be somewhat effective. It didn’t irritate my skin and left my skin feeling softer. BUT, since it retails for $200 CAD/50 mL of product (and oh, it smells absolutely TERRIBLE), I probably will not purchase the full sized bottle.
