Sunday Riley A+ High-Dose Retinoid Serum 0.5oz – Advanced-Strength Retinoid Blend

Advanced-Strength Retinoid Serum for Nightly Skincare

Sunday Riley A+ High-Dose Retinoid Serum delivers a potent 6.5% solution of stabilized retinoid blends paired with botanical, retinol-alternative extracts. The formulation combines 5% retinoid ester blend with 1% liposomal-encapsulated retinol blend and 0.5% blue-green algae to support the look of aging signs and surface concerns while staying gentle enough for regular use.

In addition to the retinoid complex, encapsulated CoQ10 is included to help address the appearance of aging- or damage-related texture, while rare Hawaiian white honey, bisabolol, cactus extract, and ginger are present to balance and soothe the skin, aiming for a calmer, more even-looking complexion over time.
