The antioxidants found in rosehip oil combat free radicals that cause sun damage. The vitamin A, combined with the oil's essential fatty acids, can help improve skintone, texture and pigmentation. While too much sun exposure can decrease collagen, vitamin C can help counteract this damage.
Rose hips contain the seeds of the rose plant. Dried rose hips and the seeds are used together to make medicine. Fresh rose hips contain a lot of vitamin C, so they share many uses with vitamin C including preventing and treating colds, flu, and vitamin C deficiencies.
