What Is MSM?

MSM (Methylsulfonylmethane) is a naturally occurring organic sulfur compound essential for the production of collagen, keratin, and elastin. It provides the sulfur needed for these critical structural proteins.

Beyond structural support, MSM offers anti-inflammatory benefits and helps improve skin permeability for better absorption of other ingredients. It is a fundamental building block for healthy skin.
