OUR RETINOL ROUTINE As retinol is a powerful active ingredient, experts recommend that you integrate it gradually into your routine to accommodate your skin to its effects. To do so, follow the skin cycling routine below. How to use Week 1 - START: Use Rénergie C.R.x. Triple Serum Retinol one night out of three. Week 2 - ACCOMMODATE: Increase use of C.R.x. Triple Serum Retinol to one night out of two. Week 3 - FULL POTENCY: Apply C.R.x. Triple Serum Retinol every night. A minimum SPF30 is the essential partner to retinol: pair with Rénergie H.P.N. UVMUNE SPF50 Cream each morning to ensure you have UV protection following retinol use.
