The peppermint plan grows primarily in North American and Europe, and the oils that can be extracted from its leaves have many uses in food, medicine and cosmetics.  In beauty, peppermint oil has been shown to promote healthy and clear skin.  The menthol that’s in peppermint oil cools, refreshes and brightens dull, tired skin. When used in lip products, it provides a cooling and nourishing effect while it smooths and softens dry skin.
