I've been using glycolic and salicylic acid for a while, and I want to include retinol in my routine. I've thought of applying each once a week (glycolic on Mondays, salicylic on Wednesdays and retinol on Fridays), but I don't know if that's enough for retinol to work. However, I'm afraid to overexfoliate if I use retinol more often without removing the acids. Does anyone have suggestions?
