The Peter Thomas Roth Camu Camu Power Cx30 Vitamin C Brightening Moisturizer contains the Amazonian Camu Camu Berry, which is full of Vitamin C. Vitamin C is used to help stimulate the production on collagen and help reduce the effects of free radical damage to the skin. This product is for anyone who is just starting to see the first signs of aging or is in the advanced stages of aging. It will help brighten your complexion and even your skin tone. It contains Vitamin E, a powerful antioxidant that helps reduce transepidermal water loss from the skin and strengthens the skin’s barrier function. When it’s combined with Vitamin C, it’s a great protector against sun damage. For best results, apply twice daily to face and neck. Be sure to follow with SPF during the day.
