Combining a powerful blend of stabilized retinoids and retinoid-like botanical extracts, this serum is designed to minimize the appearance of fine lines and encourage clearer, smoother skin. Encapsulated CoQ10 helps improve the appearance of UV-damaged skin, while soothing Hawaiian white honey, cactus extract, and ginger calm irritation to promote a more even-toned complexion. **How to use**: Apply 2-3 pumps in the evening to clean, dry skin. For new retinoid users, start with using two days on and two days off, then work your way up to using every other day, then to daily evening use. Follow with a hydrating oil or moisturizer, like C.E.O. Glow Oil. On alternate nights or mornings, use an AHA serum like Good Genes Lactic Acid Treatment to sweep away dead skin cells. For sensitive skin, apply a hydrating oil or moisturizer before applying A+ Retinoid Serum. **Key Ingredients** * Vitamin A: Unlike many other nutrients, vitamin A consists of a group of compounds - retinal, retinol, and beta-carotene. While beta-carotene is found in the dark, leafy greens we eat, retinal and retinol are often incorporated into topical skincare, helping improve your skin’s overall appearance. Stimulating collagen production, vitamin A is prized for its ability to reduce the appearance of fine lines and wrinkles over time. However, it is also used as an exfoliant, helping to shed dead skin cells and healing acne scars for a more even complexion. **About Sunday Riley** Sunday Riley is a line of layer-able formulas that unite the most advanced breakthroughs in cosmetic science with pure, potent botanicals.
