Rosehip seed oil has been used by the people of Chile for hundreds of years as a cosmetic treatment for the skin, but it has only recently gained visibility in other parts of the world. A 1983 study performed at the University of Santiago, which involved 180 participants with moderate to severe skin damage from the sun, age, radiation, or dermatitis, showed that "rosehip seed oil regenerated the skin, reduced scars and wrinkles, prevented the advancement of wrinkles and aging, and helped skin to regain its natural color and tone," according to herbalremediesinfo.com.
Cleanse the skin and pat dry with a towel.
Apply undiluted rosehip seed oil twice daily to the face and body to treat wrinkles, scars, sun damage, dermatitis, stretch marks and discoloration. Use rosehip seed oil as a daily moisturizer for very dry skin.
Massage the oil into the skin until fully absorbed. Do not rinse.
Apply rosehip seed oil twice a day for as long as desired to increase moisture in dry skin. Continue use for at least three months in the treatment of scars, photo-aging, wrinkles, dermatitis or other skin conditions.
