In general, research indicates using rosehip oil for acne is not effective. In fact, many reports indicate that rosehip oil may make acne-prone skin worse, increasing the number of breakouts and the size of the individual pimples. Although using rosehip oil to treat acne is generally not recommended, many people have reported positive effects from using the oil for other skin issues, such as acne scars, dry skin, and signs of aging, and some isolated studies show acne-prone people with very dry skin might benefit from using the oil.
In most cases, dermatologists and practitioners of homeopathic medicine will advise people not to use rosehip oil for acne. They believe the oil is too rich and argue that it is much greasier than many other oils, such as almond oil. Typically, experts assert that the oil will increase the instance of clogged pores, leading to an increase in the skin infection that causes acne.
In a few cases, using rosehip oil for acne may be acceptable. For example, people with extremely dry skin may benefit from using the oil. In addition, some people argue that the antimicrobial properties of the oil outweigh the fear of additional breakouts, pointing out that the oil can help to kill the bacterial infection that often leads to acne. It also is important to note that rosehip oil contains retinoic acid, a known form of treatment for some types of acne.
Although it may not be effective for treating acne, rosehip oil is reportedly effective for treating the scars that result from acne. The fatty acids in the oil help reverse the damage to the skin, reducing the size and color of the scar. It is also known to moisturize the skin and fight the signs of aging.
To use rosehip oil for scars, simply clean the hands and the face, and apply a few drops of the oil to clean fingertips. The oil can then be applied directly to the scars. To use it to prevent wrinkles, it can be applied all over clean skin, keeping it away from the eye area. It typically takes about 12 weeks to see results.
If using rosehip oil for acne or for scars, a dermatologist should be consulted. Additionally, the oil should not be used in combination with prescription or over-the-counter acne or scarring medications. It also is important to note that its use may increase sun sensitivity, so using sunblock and wearing protective clothing is recommended.
