I’ve been using all the products since October, and now the super c. I can say with complete confidence, these products are next level! I’m 45 my skin is plump, tone is even, no more breakouts. And the fact I can layer with no balling is perfection. I have recommended this brand to all my family and friends. And my teens now have their own kit, because I got sick of sharing.
Thanks st saj for taking the guess work out of skincare.
