Nearly all of Sunday Riley’s offerings have their own cult followings, but Good Genes is on another level. With over 1,500 five-star reviews, the lactic acid treatment remains one of the most universally lauded serums in the skincare world. And it now has a rare discount thanks to Dermstore’s current anniversary sale, running through August 19. All you have to do is use the code “BIRTHDAY” at checkout.
Sunday Riley goods are all 25 percent off in the sale, which means Good Genes’ usual price tag of $158 has been cut down to $119 (or if you get the smaller 1 oz size, now $79 from $108). You might as well buy in bulk.
