Benefits of Rosehip Oil
The benefits of rosehip oil come from the seedpods left over once the rose petals have fallen off of Rosa rubiginosa, Rosa mosqueta, and Rosa canina. It is very versatile for a number of uses due to its extremely high fatty acids content (80%), vitamin E, vitamin C, and B carotene (a form of vitamin A). It has a wonderful reputation as being skin regenerating and healing. Vitamin A, C and E work synergistically together for your cutanous health. http://www.ncbi.nlm.nih.gov/pubmed/9777769
The essential fatty acids (EFA) in rosehip oil are oleic, linolenic, and linoleic acid which provide a good balance of both omega 3, 6, and omega 9 fatty acids. Oleic acid (15-20%), an omega 9 FA, helps to create supple and moist skin. Linolenic acid (30-35%), an omega 3, helps to improve the skin's softness and moisturizers the skin as well. Linoleic (44-50%) acid, an omega 6 FA, helps to preserve the cell's barrier to the environment and necessary for the structure of cell membranes.
The fact that this oil absorbs very quickly add to the benefits of rosehip oil. You may often hear it referred to as a "dry oil" and this is due to the rapid absorption leaving less of an oily/greasy feel. Since rosehip oil is easily absorbed it is more readily able to penetrate the deeper skin layers for a more therapeutic effect.
Rosehips is also high in vitamin C. It contains about 1700-2000 milligrams vitamin C per 100 grams . And more surprisely, vitamin C is more readily absorbed through the skin than if taken orally. If vitamin C is taken orally, only 16% of it is absorbed.
Benefits of rosehip oil also come from vitamin A, contained in the form of trans-retinoic acid or also known as retinol. As this moelcule is smaller it can penetrate your skin more deeply, allowing it to improve your skin's moisture content and reduce wrinkles and appearance of fine lines. Rosehip oil contains a natural form of tretinoin, an agent that has been used successfully in pharmaceutical products to treat acne and wrinkles. Since the tretinoin in rosehip is in a natural state and part of a complex system of unsaturated fatty acids, it is released slowly and poses no risk of overdose.
Another benefit of rosehip oil's vitamin A is that it acts on our skin's fibroblasts. These cells are what stimulate collagen production to add firmness and elasticity to your complexion. The production of collagen is assisted by rosehip oil's vitamin C, which goes through a process known as hydroxylation to create hydroxyproline, an essential component of collagen production. http://www.ncbi.nlm.nih.gov/pubmed/8313238
Studies have shown the positive effects of rosehip oil when treating skin ulcers. A 26% oil concentration was significantly more effective than the placebo group. http://www.ncbi.nlm.nih.gov/pubmed/2214931
The following review articles lists a number of studies done demonstrating the benefits of rosehip oil for radiations burns, surgical scars as well of UV induced photo-aging. Again, the Tretinoin component may be rosehip's strongest asset to facilitate skin rejuvenation. http://mettamassagetherapy.com/reprints/rosehip_oil.pdf
Another ingredient in rosehip oil is lycopene, a powerful anti-oxidant. This acts as a free-radical scavenger to protect your skin from environmental damage including UV light. Photo-aging and hyperpigmented spots can be dimished with rosehip oil.
When used in concentrations over 10% rosehip oil may aggravate acne.
