Sunday Riley A+ High-Dose Retinoid Serum is formulated with retinol and an algae extract, honey extract, bisabolol, and ginger extract.

How do I use it: Apply two to three pumps in the evening to clean, dry skin. For new retinoid users, use two days on, two days off. Work your way up to every other day, then to daily, evening use. Follow with a hydrating oil or moisturizer (not included).
