Magnesium has been recognized scientifically as a cofactor for many enzymatic reactions in bodymetabolism, it is required for DNA synthesis, reproduction, and protein synthesis. Moreover, magnesium is essential for the regulation of muscular contraction, blood pressure, cardiac excitability, vasomotor tone, nerve transmission and neuromuscular conduction.

There are articles that the propagation of transdermal magnesium is scientifically unsupported.

The primary function of the skin is to provide a barrier between the body and the external environment. This barrier protects against the permeation of ultraviolet (UV) radiation, chemicals, allergens and microorganisms, in addition to the loss of moisture and body nutrient. This means that the absorptive capacity of healthy skin for substances from the outside is very limited. This becomes evident particularly in the limited application for topical drugs. To get through the skin, a substance must penetrate the epidermis or has to be absorbed by sweat glands or hair follicles.

By helping regulate neuromuscular signals, muscle contractions and balancing calcium levels within the body, magnesium can help muscles relax and contract, easing pain and reducing cramps as well as pain in overworked muscles.

I used Mgoil, 31% Mg Cl aqua solution.

Magnesium chloride, MgCl2, is a soluble compound that dissociates in aqueous solution to form magnesium cations, Mg2+, and chloride anions, Cl−

 And DMSO, Dimethyl sulfoxide (DMSO) is an organosulfur compound with  the formula (CH3)2SO. This colorless liquid is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water. It has a relatively high boiling point. DMSO has the unusual property that many individuals perceive a garlic-like taste in the mouth after contact with the skin

DMSO is frequently used as a solvent for chemical reactions involving salts, most notably Finkelstein reactions and other nucleophilic substitutions. It is also extensively used as an extractant in biochemistry and cell biology. Because DMSO is only weakly acidic, it tolerates relatively strong bases . Because of its high boiling point, 189 °C (372 °F), DMSO evaporates slowly at normal atmospheric pressure.  It also used in biopreservation, especially stem cell banking. DMSO is an effective paint stripper, being safer than many of the others such as nitromethane and dichloromethane

Use of DMSO in medicine dates from around 1963, when an Oregon Health & Science University Medical School team,  discovered it could penetrate the skin and other membranes without damaging them and could carry other compounds into a biological system. In medicine, DMSO is predominantly used as a topical analgesic, a vehicle for topical application of pharmaceuticals, as an anti-inflammatory, and an antioxidant. Because DMSO increases the rate of absorption of some compounds through biological tissues, including skin, it is used in some transdermal drug delivery systems. Its effect may be enhanced with the addition of EDTA. It is frequently compounded with antifungal medications, enabling them to penetrate not just skin but also toenails and fingernails.
