A natural history

Yeast is one of humanity's oldest and most quietly magical partners. The same microbe that has leavened bread and fermented wine and beer for thousands of years is a treasure chest of skin loving nutrients, rich in vitamins, amino acids, and a soothing fiber called beta glucan. From the brewery and the bakery comes an unlikely beauty ingredient.

That ancient craft of fermentation has been reborn in modern skin care, where cultured yeast extracts are prized for a conditioned, radiant look. It is a fitting second life for so humble a helper, the quiet worker behind our daily bread now lending its richness to the skin.

What it does for your skin

Yeast extract is valued for its beta glucan, a soothing, conditioning fiber. In cosmetic study, a yeast derived beta glucan helped protect skin cells against ultraviolet stress and supported the renewal of the skin's surface.^[1] In preclinical work, beta glucan supported the skin's natural repair in a dose dependent way.^[2] In a formula yeast extract is a soothing, fermented ingredient that helps stressed, dull skin look calm, conditioned, and healthy. Cosmetic and preclinical studies both point to that soothing, conditioning support.
