Why experts disagree with claim that rubbing magnesium oil on feet balances insulin and cortisol levels, reduces cravings and supports hair growth

Magnesium is an essential mineral that supports many bodily functions. There are many rich sources of magnesium that can be had in one's diet including almonds, bananas and soy (Photo: Getty Images/Thinkstock)

As such, when social media claimed that magnesium is involved in over "300 biochemical reactions in your body, and most people are deficient without even knowing it" and as such spraying it over your feet can control insulin and cortisol levels, aids faster metabolism, along with thick and healthy hair and no more sugar cravings, we decided to verify from experts.

From a skincare perspective, the claims about magnesium absorption through the skin are not scientifically proven, asserted Dr Vishalakshi Viswanath, consultant dermatology, KIMS Hospitals, Thane. (Photo: Getty Images/Thinkstock)

The skin primarily acts as a protective barrier. "While it can absorb certain substances under specific conditions, there is limited evidence that magnesium applied in oil or spray form can deeply penetrate the skin and affect internal processes," said Dr Viswanath.

Who should be careful? Dr Viswanath said that people with sensitive skin should be careful, as magnesium oil can sometimes cause itching, redness, or irritation, especially on areas like the feet or scalp. "There is no strong dermatological research backing the claims that it can directly improve hair thickness or treat hair loss," said Dr Viswanath. (Photo: Getty Images/Thinkstock)

That said, applying magnesium oil especially with a light massage may promote relaxation, which can help with sleep. However, it should not replace proven skin care methods, a balanced diet, or medical treatment, said Dr Viswanath. (Photo: Pexels)
