Can I use PROVEN with active treatments (retinol, acids, Vitamin C)?Updated 5 hours ago

Yes — with care. PROVEN formulas already include the actives your quiz recommends, so layering additional retinols, AHAs/BHAs, or high-strength Vitamin C may overlap or amplify ingredients already in your formula. The safest path: indicate what you're using during the quiz so your formula adjusts. If you start a new active treatment after PROVEN, contact our Customer Care team — they'll confirm whether to layer, alternate, or pause to avoid irritation.
