Dermatologist Shereene Idriss recommends a one-step nighttime routine: glycolic acid applied an hour before bed, several times a week from forehead to chest. Skip it if you have sensitive skin.
This could be your one step nighttime routine that you put on an hour before you go to bed and then you just sleep through the night, waking up to the softest skin of your dreams. Exfoliating acids are key to looking smooth and fresh and having skin like a baby's butt. Glycolic acid specifically is great not only to buff your skin, but also to hydrate it. And yes, I do use this much when I am going from my forehead down to my chest several times a week. I do this. If you can tolerate exfoliating acids and you do not have sensitive skin.
