Can I use Tazorac at night and retinol in the morning?
You’d be wasting your money since light tends to inactivate the retinoids (Renova, Tazorac, tretinoin, Retin A, retinol, etc.). You’d be far better off adding a good antioxidant Vitamin C based serum like the SkinCeuticals C&E Phoretin which has a new gel form and travel friendly packaging. It’s expensive but worth it. Or, add the TNS Recovery (growth factors). Use either one in the morning under your sunscreen. I haven’t added the gel yet to our products but will soon. Dr. I
