While there is scientific research to support the use of magnesium in general for treating some health conditions, this evidence is not for magnesium oil specifically, suggests Berkeley Wellness. Dr. Dendy Engelman of the Manhattan Dermatology and Cosmetic Surgery notes that the magnesium from the oil does get absorbed through the skin, and some benefits of its use can include hydrated skin, bowel regulation and stress reduction, states Huffington Post.
Magnesium in general has been researched to help with managing diabetes, helping reduce migraines and helping with blood pressure management, but the scientific studies have not been conclusive, mentions Berkeley Wellness. It's suggested that individuals get their magnesium through foods rather than supplements like tablets and oils.
While there are additional claims that magnesium oil can help with skin irritation, there is not any scientific evidence supporting this, says the Huffington Post.
