Magnesium Carboxymethyl Beta-Glucan description

Magnesium carboxymethyl beta-glucan, also referred to as CM-Glucan Forte, is a soothing skin care ingredient that’s particularly beneficial for skin exhibiting signs of a compromised skin barrier, like dryness and flakiness. Beyond its soothing abilities, it taps into beta-glucan’s humectant properties, allowing it to help skin retain moisture. This soothing agent’s created through the combination of the polysaccharide beta-glucan, extracted from the cell walls of baker’s yeast, and the mineral magnesium, which is used to solidify the stability of beta-glucan’s large molecule size. Beyond skin care, this ingredient is also used in hair care formulas to assist in calming scalp irritation. Magnesium carboxymethyl beta-glucan is recommended for usage in skin care preparations in percentages between .2 and .1%.
