The pristine source for Ancient Minerals magnesium products lies within a deep underground seabed in Northern Europe–nearly two miles beneath the surface—referred to as the Ancient Zechstein Sea. It is extracted from the earth by a process known as solution mining, and it is globally the most coveted source of naturally occurring magnesium chloride in existence.

Rinsing off magnesium oil or magnesium gel after use is a matter of personal preference, and depends on how much you apply and where it is applied on the body. Typically, the more magnesium oil or gel used per application, the higher likelihood you may prefer to rinse it off. In roughly twenty minutes your skin can take full advantage of topically applied magnesium, and it may be safely removed at that point. Keep in mind, also, that Ancient Minerals magnesium gel is designed not to be fully absorbed into the skin, so rinsing off after applying is a fairly common practice.
