Rosehip oil is packed with antioxidants, such as vitamin C, vitamin E, and beta-carotene, which can help combat free radicals and oxidative stress. These antioxidants may help reduce the signs of aging, such as fine lines, wrinkles, and uneven skin tone, and promote a more youthful appearance. Rosehip oil contains natural retinoids, which are derivatives of vitamin A. Retinoids can aid in the regeneration of skin cells and promote a smoother and more even skin texture. They may also help improve the appearance of scars, stretch marks, and hyperpigmentation.
