Your products aren't working. Have you ever considered that maybe, just maybe, you're using your products incorrectly? I'm a 39 year old board certified dermatologist. You cannot have an exfoliating acid as a toner in a serum, in a wash, in a pad, in every step of your routine. And worse, you guys are using it way too often. I. E. Every single day, if not even twice a day, going to wreck your barrier and inflame your skin in the process. It should be reserved for the nighttime only, maximum three to four times a week.
