Rose hip seed oil is a pressed seed oil, extracted from the seeds of the wild rose bush (Rosa moschata or Rosa rubiginosa) in the southern Andes. Rosehip seed oil can also be extracted from Rosa canina, which grows in many regions of the world including South Africa and Europe.
The oil contains provitamin A (mostly beta-Carotene). It has been wrongly said to contain retinol (vitamin A) which is a vitamin solely made by animals from provitamin A. It does however contain levels (up to .357 ml/L) of tretinoin or all-trans retinoic acid, a vitamin A acid that retinol converts to.
Similarly, while the fruit is rich in vitamin C, the oil does not contain any, as it is a water-soluble vitamin.
It is commonly used in skin care products. Although there is anecdotal evidence which suggests rose hip seed oil assists in the healing of scar tissue, there is little in the way of reputable scientific evidence.
