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.
