This is a light but rich moisturizer with the potent antioxidant Coenzyme Q10. A must have rejuvenation product for aging skin! Easily tolerated by all skin types, it works well with both anti-aging and oily skin regimens. Gentle for more sensitive skin or for patients who cannot use Glycolic Acid. Contains Vitamins A, C and E for enhanced free radical damage repair after sun exposure. I love the luxurious, lush feel of it on my face so much that I apply it several times a day! Use AM or PM.
