Science
Mechanism of Action
Trehalose functions primarily as a humectant, drawing and retaining moisture to significantly elevate skin hydration and fortify the skin's natural barrier against dehydration. It stabilizes vital proteins and cellular membranes by forming hydrogen bonds, effectively substituting water molecules during cellular stress, thereby preserving cell structure and function. Additionally, trehalose exhibits powerful antioxidant properties, safeguarding the skin from oxidative stress induced by external aggressors like UV radiation and pollution. It can also modulate autophagy, a cellular process vital for clearing damaged proteins and promoting cell survival and repair, and possesses anti-irritant qualities contributing to overall skin barrier restoration.
