Rosehip Seed Oil
Rosehip Seed Oil is renowned for its outstanding skin regeneration properties and for toning
down scar tissue.
The rosehip (Rosa aff. rubiginosa) is found in South America,
in particular in Peru, Chile and Argentina. It belongs to the Rosaceae family,
subfamily Rosoideae genus Rosa. The oil obtained from the seeds has a high
content of non-saturated fatty acids, like oleic, linoleic and linolenic acid. Due
to its physical and chemical characteristics, as well as its behaviour, it is
considered a siccative oil. It is commercially obtained by extraction with organic
solvents and purified by winterization, in order to eliminate the triglycerides of
higher saturation. Stabilizers are added for avoiding rancidness.
Besides non-saturated fatty acids, the presence of carotenoids, flavonoids, vitamin C,
o ketonic compound (namely 3-penten-propyl-ketone) and, recently, trans-retinoic acid has
been detected. The latter could be responsible for some of the pharmacological and
therapeutic properties of Rosehip Seed Oil.
Among dermatological studies:
- Application on aged skin
On some skin troubles like superficial wrinkles, chestnut spots and ephelides, good results
have been obtained. After 16 weeks of treatment, wrinkles disappeared and spots become imperceptible.
- Application effect study
After three months of two applications a day, scars were less marked, they had no crests, skin
elasticity was increased and the zone colour looked better.
- Depigmentor effect study
A certain depigmentor effect of pure Rosehip Seed Oil has been observed. After 120 hours of
application under normal atmosphere and absence of light, a diminution of 18% of the
Dopamelamine concentration was detected.
