microbiome skincare

I've seen a lot of brands that launch products with the claim of "balancing skin microbiome" and "microbiome friendly" with ingredients such as: -Prebiotics: fiber / the source of food for the bacteria (Oats, Inulin) -Probiotics: the live bacteria itself (Lactococcus) -Postbiotics: the end product of bacterial fermentation (Lactobacillus ferment, Bifida ferment lysate) Have you guys tried any product which contains that sort of thing? What's your comment on that?
