A+ High-Dose Retinoid Serum combines a five percent retinoid ester blend, one percent liposomal-encapsulated retinol blend, and a half percent blue green algae with natural retinoid-alternative activity. This serum fights the signs of aging and improves the look of congested and UV-damaged skin. Encapsulated CoQ10 helps to improve the appearance of aging or damaged skin, while Hawaiian white honey, bisabolol, cactus extract, and ginger balance and soothe the skin for a calmer, more even-toned complexion. 

New to retinoids? Start using A+ two nights a week, and then take two nights off. Gradually work your way up to every other night, and then every night.
