Their biome balancing serum has both SAVED and TRANSFORMED my skin!!!! The serums that I used to buy from Sephora RUINED my skin barrier and I now have perioral dermatitis which can be inflamed and hard to deal with! I got a dermatologist and she recommended this for me to try ...and I will NEVER live without it again - the tiniest bit goes a long way and it has fixed my entire skin barrier. Cannot talk better about a skincare product!
