Anticipated Reactions
Redness, flakiness, dryness, burning, or stinging are all normal, anticipated reactions when starting retinol. With regular product use, skin will acclimate, revealing a smoother, more even-toned and youthful-looking complexion. Pair your retinol with a ZO® functional hydrator to minimize anticipated reactions. Consult a physician for customized retinol protocol. Like prescription retinoic acid, retinol will make your skin more sensitive to the sun. Wear SPF 30 or higher daily.
