From Dr. Starkey - "Magnesium is one of the most important minerals for human health. It's the fourth most abundant mineral in the body and participates in over 300 biochemical reactions! What about the skin? Magnesium is not only great for the body, it's also great for the skin. In studies involving the uses and benefits of topical magnesium oil, magnesium has been shown to break apart different fats and oils which helps aid in reducing skin oiliness. Though magnesium has stress-relieving benefits internally, it can also help to reduce stress-related skin irregularities and blemishes. I believe that everyone can benefit from using magnesium oil."
