A+ High-Dose Retinoid Serum

This serum pairs actual retinol with hydroxypinacolone retinoate, a gentler retinoid ester, so you get a strong dose of vitamin A without as much of the irritation straight retinol can cause. CoQ10 and honey extract are added for antioxidant support and to help offset dryness. Sunday Riley markets it as an option for people building up retinoid tolerance as well as more experienced users.
