Rosehip oil has been very popular the last few years and for good reason. It's a dry or oil, meaning it absorbs quickly and does not leave behind a greasy residue. It's also high in essential fatty acid like alpha Like alpha-linoleic and linoleic acid which are essential to skin structure. The omega 6 fatty acids are integral to epidermal barrier function, regulating the skins elasticity and hydration. It's also rich in all-trans-retinoic acid, the bioactive form of vitamin A, which affects cell turnover and collagen production. I love Luzern's Rosehip oil, and Rehydrate oil, which combines Rosehip oil with hyaluronic acid.
