There is no known way to 100% prevent stretch marks during pregnancy, but a few things are said to help, and one of them is to keep the skin on the stomach well lubricated both inside and out. This means that the mother-to-be should drink lots and lots of water, and should use a chemical free form of intense lubrication on the skin. This massage bar comes in a handy stick for ease of use. It contains the organic, unrefined base ingredients of Beeswax, Cocoa Butter, Shea Butter, and Avocado Oil. All of these have been shown to have wonderful lubricating properties. The sticks also contain a 1% organic essential oil formulation of Lavender, Helichrysum, Frankincense and Geranium. These are all skin nourishing oils that are deemed safe for pregnant women by Robert Tisserand, current guru of essential oil safety. Shea Butter comes from a nut, so if you are allergic you should not use this stick. Please contact us and we can specially formulate a massage stick for you that does not contain Shea Butter. 2.8 oz. net wt.
