If you've struggled to get along with retinol serums before, due to them drying out your skin, and you don't want to add multiple steps to your night time skin regime then Olay Regenerise Retinol 24 Max (£44) could be for you. This night cream contains retinol, as well as 40 percent moisturising ingredients like hyaluronic acid, to help your skin absorb the potent ingredient without causing to much harm to your skin barrier.
