Sunday Riley A+ High-Dose Retinoid Serum

One of the most bio-available non-prescription forms of vitamin A products on the market, A+ High-Dose Retinoid Serum is a pro-strength formula for those who want serious results without the unwanted side effects of traditional retinol formulations (reduced appearance of side effects like flaking, redness, and irritation compared to high-strength retinol and retinoid products is visible after one use). Combining 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. Still on the fence? In addition to reducing signs of ageing like fine lines and wrinkles, A+ features encapsulated CoQ10 to help improve the appearance of ageing or damaged skin, while Hawaiian white honey, bisabolol, cactus extract and ginger balance and soothe the skin for the appearance of a calmer, more even-toned complexion.
