Rosehip oil is a dry oil that penetrates to the deepest layers of the skin where it regenerates cells, increasing collagen production. (Note that rosehip oil and rosehip seed oil are the same thing; you’ll see it marketed under either name). It is rich in vitamin C, Omega-3 and Omega-6 fatty acids, all of which are known to help heal scar tissue. It is also high in retinoic acid, which studies show reduces the appearance of wrinkles and brightens skin. Essentially, it’s anti-aging, healing, and brightening.
