Sunday Riley A+ High-Dose Retinoid Serum combines 5% retinoid ester blend, 1% liposomal-encapsulated retinol blend, and 0.5% 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 rare, Hawaiian white honey, bisabolol, cactus extract, and ginger balance and soothe the skin for the appearance of a calmer, even-toned complexion.
Apply 1-2 pumps in the evening to clean, dry skin. For targeted instructions, see below: 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, like C.E.O. Glow or Juno. Use an AHA serum, like Good Genes Lactic Acid Treatment, on alternate nights to sweep away dead skin cells.
Precautions: They do not recommend using retinoids while pregnant. Please consult your doctor before use if you are pregnant or breastfeeding. We always recommend using sunscreen during the day, if using retinoids in the evening.
