Rosehip oil is pressed seed oil, extracted from the seeds of the wild rose bush Rosa rubiginosa found in the southern Andes. Prized since the ancient times for its valuable healing benefits, rosehip oil is loaded with skin-nourishing vitamins and essential fatty acids. It also contains phenols that have been shown to have antiviral, antibacterial, and antifungal properties. Rosehip oil is often used as carrier oil for essential oils which are too intense to put on your skin directly.
