“Rosehip seed oil contains a blend of bioactive ingredients that can potentially be beneficial to the skin, for example vitamin C, vitamin E, carotenoids, and essential fatty acids,” adds Dr. Julia Tzu, a dermatologist who is also an assistant clinical professor of dermatology at New York University. “It may be potentially beneficial as an anti-aging product because of the antioxidant ingredients it contains. Its high vitamin C content suggests that it may also be useful for treating dark spots, since vitamin C decreases the pigment-producing ability of the skin.”
