Why It Works for Pregnancy
Kate Middleton may be onto something. Those considering using rose hip oil for pregnancy, whether to reduce hyperpigmentation and stretch marks or ease dry skin, should consider the following evidence. In a study of 20 women ages, 25 to 35 conducted by Dr. Bertha Pareja and Dr. Horst Kehl, daily applications of rosehip oil were linked with wrinkle reduction and the fading of sun-damaged skin. In addition, all subjects of the study, conducted at the Faculty of Chemistry and Pharmacology at the University of Chile in the 1980s, reported a “visible improvement” in skin appearance.
During pregnancy, the skin experiences a number of changes. As the baby grows, the skin stretches and can become blotchy (or patchy). That’s where rosehip oil can be helpful, as it increases the skin’s ability to produce new skin cells. As these new cells take the place of old ones, darker pigmentation spots will start to lighten.
Usage Tips
Due to its susceptibility to rancidity, rose hip oil can have pure vitamin E oil added to improve shelf life. Rose hip oil classifies as a dry oil and absorbs quickly into the skin. You can apply the oil directly to the face using gentle, massaging motions or use it skin care recipes. Apply the oil twice a day and allow it to absorb into the skin. Rose hip oil doesn’t protect against sun burn. While it can prevent and reduce acne scars, it shouldn’t be applied directly to active acne.
