Rosehip oil works to effectively improve the appearance of stretch marks and scars, especially those resulting from acne. Rosehip oil has a similar pH balance to that of the natural oil found in human skin, which means that it does not clog pores. It is extremely effective for use on ageing and dehydrated skin, and works to hydrate, rebuild and replenish the skin. Rosehip is an effective treatment of various skin burns, eczema and dermatitis, as well as having the ability to lessen the visibility of wrinkles and uneven skin tone.
