Rosehip is a fairly new ingredient in modern cosmetic skincare products but has gained a great following by people in the know, as it contains lots of vitamin C, which is not only healing but is also a wonderful ingredient in anti-aging products.
This form of vitamin C in the oil medium is non-irritating to the skin and prevents the "Fenton reaction", which is a normal reaction that water-soluble vitamin C has when interacting with the iron in the skin. A hydroxyl-free radical forms in this action - which does not happen when the vitamin C in rosehip oil interacts with the skin.
It acts as a fixative and is refrigerant, while also having astringent and diuretic properties. It has exceptional emollient properties, while also acting as an antioxidant.
It is high in GLA, which helps reduce the signs of aging, especially the fine lines around the eyes (crow's feet) and lines around the mouth, as well as combating the drying effects of the sun, environment, and climate.
Effectiveness of rosehip oil
In the research done by Dr. Bertha Pareja and Dr. Horst Kehl, it was found that daily applications of rosehip oil helped with wrinkle reduction, as well as fading sun-damaged areas of the skin. Twenty women aged between 25 and 35 years were used as test subjects, over a four-month period, and all reported a visible improvement to the skin.
Due to the high levels of the fatty acids - linoleic (47.4%) and linolenic (33%) - it helps the skin to heal and speeds up regeneration while preventing the formation of thick keloid scar tissue (the over thickening and formation of fibrous tissue of the skin when forming scar tissue) and is helpful in healing burns, scars and stretch marks.
The success rate of treating and reducing the formation of keloid scar tissue and loosening up fibrous cords is successful for accidental and surgical scars.
Fatty acids are essential building blocks of cellular membranes, to allow efficient transportation of nutrients from the extracellular space into the intracellular environment where metabolism takes place.
Besides the non-saturated fatty acids, the presence of carotenoids, flavonoids, and trans-retinoic acid has also been detected in this oil and these could be responsible for some of the pharmacological and therapeutic properties of rosehip oil.
In a further study, it was found that it was useful when used on surgical scars (applied twice daily). The scars were less apparent, the skin more elastic and the color also improved significantly compared to patients not using them. The same success is reported on burns when the oil was used to reduce scarring and returning the tissue to its normal and natural coloring.
It penetrates the skin very quickly, making it a good moisturizer, and with all the other positive properties, and its tissue regeneration action, it is easy to understand why it is also described as the "oil of youth".
