Retinoids are available over-the-counter (as retinol) or with a prescription (as tretinoin, adapalene, and tazarotene). Because retinoids can cause some irritation at first, Hirsch recommends applying a gentle moisturizer, letting it soak in for at least 30 minutes, then applying your retinoid cream.
