We’re not trying to be dramatic here, but magnesium (Mg) is such an essential mineral that, without it, life as we know it would probably not exist. Indeed, a single magnesium atom is at the heart of each chlorophyll molecule, and chlorophyll is what allows photosynthesis – the very basis of plant life!

Magnesium is also known to play an important role in many natural processes in the body. It is often discussed in relation to general wellbeing and normal body function, highlighting how important it is for overall balance.

Applied externally, it is thought that magnesium may support muscle recovery and contribute to a sense of relaxation after physical effort – although some doubts persist about its absorption through the skin, and further studies should be conducted.

People have been bathing in magnesium-rich water for centuries, whether in the Dead Sea or the hot springs of Epsom and Bath, appreciating their use in traditional bathing rituals. Over the past decades, a few studies and trials have attempted to understand why that was. They have suggested that magnesium chloride oil may interact with the skin barrier and be used in topical (applied directly to an area of the skin) or bathing (soaking in a magnesium-rich bath) applications.

In Lush products, you will come across several forms of magnesium. Magnesium carbonate and trisilicate, for example, are usually found in powdered products. They are anti-caking agents with absorbent qualities, ideal in deodorants, among others.

Magnesium chloride and sulphate are often associated with use in bathing and body care routines. Magnesium sulphate (also spelt sulfate) is the scientific name for Epsom salts. These are very often used as bath salts, providing a moment of relaxation in bathing rituals. Magnesium chloride can also be used for soaks but is more commonly mixed with a little water to create an oily solution called magnesium oil. This one is used for massages and topical application and is often described as more concentrated than Epsom salts.
