When should I use the Retinol Serum?Updated a year ago

The best time to use the Enzyme-Active Retinol Serum is in the evening, but you can use it in the daytime if that suits your routine better. It makes the most sense to apply our retinol serum in the evening to help your skin self-repair as you sleep without being exposed to oxidative damage. Plus, this gives you room in the daytime to use our protective Vitamin C Superserum.
