30s & 40s Skincare Routine: How to Use Retinol & Acids Like a Dermatologist! | Dr. Idriss
"I'm going to apply this from the top of my head down to my tatas, avoiding the eye area because the skin is more sensitive there and the crevices around my nostrils because it can build up there. And we're going to leave this on for 15 minutes. An advanced move for really not the beginners of the group is to leave this guy on overnight. If I have a big event, if I'm exhausted, if I want my skin to look really good the next day, I usually apply it from here to here, leave it on overnight, go to sleep, wake up, and wash it off. And my skin the next day is as smooth as a baby's butt."
