Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Locks in moisture
Traditional Use
Naturally present in fermented foods and the human microbiome for centuries. Modern probiotic skincare use emerged in the early 2000s after research showed these beneficial bacteria could support skin barrier function and reduce inflammation.
