Rosa Canina Fruit Extract, commonly known as Rosehip Seed Oil or Dog Rose Oil, is the oil extracted from the seeds of the rosehips, which are the fruits left behind after a rose has flowered. Rich in antioxidants, anti-inflammatories, essential fatty acids, lycopene and vitamins A, C, E and F, rosehip seed oil increases cell turnover in the skin and helps to fight free radical damage caused by the sun and environmental toxins. The oleic, palmitic, and linoleic acids assist in cell regeneration, while the high vitamin C content helps to stimulate collagen production, resulting in increased elasticity and hair growth. It also absorbs quickly, creating a protective barrier that keeps the hair from becoming dehydrated.
