Applying magnesium gel on the skin may allow the magnesium to become effectively absorbed into the body and encourage cell rejuvenation. Magnesium gel massages may help to reduce inflammation, lower muscle pain and stiffness, soothe skin rashes and nourish sun-damaged skin. Scalp massages with magnesium gel may improve blood circulation, which stimulates hair follicles to grow rapidly and bring a natural luster to hair. A small amount of gel can be added into bathwater or foot soak for a relaxing experience.
