Sunday Riley’s bestselling Good Genes Lactic Acid Treatment is 25% off right now


This skin-brightening treatment from Sunday Riley, which is on sale with promo code CHEERS, helps improve the overall appearance of skin in several ways, thanks to lactic acid, an acid derived from lactose in milk. Lactic acid is a type of alpha-hydroxy acid, commonly called an AHA, which is also one of the main ingredients in chemical exfoliants. The Good Genes Lactic Acid Treatment powers the skin to produce natural collagen and helps smooth and firm the skin by reducing the appearance of fine lines and wrinkles.
It also has licorice, lemongrass and aloe, which help reduce hyperpigmentation and create a more even complexion, according to the brand. It’s also compatible with all skin types — you only have to apply 1 to 2 pumps to clean skin in the morning or evening and leave it on. For sensitive skin types, the brand recommends only leaving it on for 15 minutes before rinsing.
