Even though the systemic absorption of topically applied over-the-counter retinoids is low, we recommend that you avoid prescription retinoids (Renova, Retin-A, Differin, Tazorac and generic tretinoin) and over-the-counter products with retinol and its derivatives due to their relation to prescription retinoids. Consider switching to an anti-ageing product that does not contain retinol or its derivatives (retinyl retinoate, retinaldehyde, retinyl linoleate, retinyl propionate or hydroxypinacolone retinoate). For additional ingredient questions during pregnancy, be sure to consult with your doctor and follow their recommendations and read our Expert Advice Article to learn more about skin care products that are safe to use during pregnancy.
