Obagi Retinol 1.0 28g

Full strength 1.0% retinol for experienced retinol users. It is not a starting point: move to it once you use the 0.5 several nights a week without irritation.

Apply a pea-sized amount to clean, dry skin at night, and use it less often than the 0.5 at first. Wear sunscreen every morning. If you get stinging, redness or flaking that does not settle, go back to the 0.5. Do not use retinol if you are pregnant, planning a pregnancy or breastfeeding.
