FAQ
Q1: Does probiotic skincare work?
A: Yes, but not through live probiotics — preservation kills them. Effective products use ferments, postbiotics, and prebiotics to support the microbiome.
Q2: What do ferments do for skin?
A: Fermentation breaks actives into smaller, more bioavailable molecules and produces postbiotics that signal the skin.
Q3: Are live-probiotic claims real?
A: Live probiotics are impractical to preserve in cosmetics, so credible brands frame claims around barrier support instead.
