An extremely simple, natural molecule (trimethylglycine) found in numerous plant sources. The one we use is taken from beets. It is a substance that is useful in nature in protecting plant cells. Applied to the skin, it has extraordinary hydrating properties similar to glycerin. Thanks to the presence of numerous methylic groups, this active ingredient also increases cell turnover in the stratum corneum, thereby renewing the skin and lending greater freshness to sensitive skin.
