What does rosehip oil contain?
Its seeds contain 8% oil and more than 70% fiber, so its yield is very low, compared to the extraction of oil that is carried out in other seeds or nuts (50% or more of oil) .
However, rosehip oil is very interesting for its active components in dermatology, such as linoleic and linolenic acids, retinol and tretinoin.
Rosehip oil is obtained from sweetbriar rose ( Rosa rubiginosa) or other related wild rose species or varieties , such as musk rose (Rosa moschata) or dog rose (Rosa canina)
Rosehip oil fatty acid composition table
All wild rose oils have a similar composition, in which polyunsaturated fatty acids predominate (70-80%):
|Composition or rosehip oil in %|
|Saturated fatty acids|
|Eicosanoic acid (Arachidic acid)||0,72|
|Monounsaturaturated fatty acids|
|Oleic acid omega 9||14,12|
|Polyunsaturated fatty acids|
|Linoleic acid (omega 6)||44,13|
|Linolenic acid (omega 3)||32,21|

Non-fatty components of rosehip oil
In addition to its fat content, rosehip oil may contain:
– Retinol (provitamin A). The oils obtained by cold pressure contain 700% more tretinoin or trans-retinoic acid (active regenerating ingredient of the skin) than those extracted with solvents and other methods.
