Methylsulfonylmethane (MSM) is a naturally-occurring chemical in the body, some green plants and animals, and can also be synthetically produced in a laboratory. It is believed to provide sulfur molecules for the synthesis of other compounds within the body.
MSM is beneficial for all skin types and age groups. It has shown to be very successful in treating conditions such as acne, eczema, psoriasis, as well as sensitive and troublesome skin. It works to keep skin healthy and strong, thus preventing early aging and skin damage.
Dimethyl sulfone (DMSO2) is an organosulfur compound with the formula (CH3)2SO2. It is also known by several other names including methyl sulfone and (especially in alternative medicine) methylsulfonylmethane (MSM). This colorless solid features the sulfonyl functional group and is the simplest of the sulfones. It is relatively inert chemically and is able to resist decomposition at elevated temperatures. It occurs naturally in some primitive plants, is present in small amounts in many foods and beverages, and is marketed (under the MSM name) as a dietary supplement. It is sometimes used as a cutting agent for illicitly manufactured methamphetamine. It is also commonly found in the atmosphere above marine areas, where it is used as a carbon source by the airborne bacteria Afipia. Oxidation of dimethyl sulfoxide produces the sulfone, both under laboratory conditions and metabolically.
