Sunday Riley A+ High-Dose Retinoid Serum

Serums USA Approx. $122

A 6.5 percent retinoid blend: five percent retinoid esters, one percent liposomal retinol and half a percent of an algae with retinoid-like activity, softened with honey and bisabolol. The strongest retinoid in this edit, from the Houston brand, and the least expensive thing on the page.
