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. How to use: Apply 1 to 2 pumps in the evening to clean to dry skin. New retinoid users should use two days on, two days off. Work your way up to every other day, then to daily evening use. Advanced retinoid users should use daily in the evenings. Follow with a hydrating oil or moisturizer. Use an AHA serum on alternate nights to sweep away dead skin cells. For sensitive skin, apply a few drops of a gentle, hydrating oil to your skin before applying the serum. 1 oz.
