Ground rose hips added to soap offer a natural exfoliate. Essential oils extracted from the seeds within the hips and added to soap bestow numerous restorative benefits.
A rose hip is the bulbous fruit of the rose plant. Allowing the hips to mature provides the essential ingredient for rose hip soap; the seeds create essential oil; the hip adds color and acts as an exfoliant.
Seeds inside the rose hips are high in vitamin A, or retinoic acid. Extracting oil from the hip seed and infusing it in soap allows vitamin A to bind to cell receptors in the skin, thus increasing regeneration of skin cells.
Oil extracted from hip seeds not only infuses the soap with vitamin A, it adds moisturizing properties to the soap.
A scientific paper compiled by Dr. Bertha Pareja of the University of San Marcos, Lima, Peru and Dr. Horst Kehl, University of Missouri, Kansas City, details a two-year study of the benefits of the oil extracted from rose hips. Results indicated that after four months use, wrinkles and age spots created by sun damage showed remarkable improvement.
