Postbiotics, just a trend or more than that?

The use of postbiotics in the skincare industry is, currently, a trend. As is normal with trends, they come and go, but postbiotics have been in use in the skincare industry for more than 4 decades. They were never talked about, though, or part of the story telling around the products they were part of. They were in the formulation to perform a job as an active ingredient. A ‘silent partner’, so to say. As a matter of fact, postbiotic active ingredients might even be considered to be a success story among the hundreds of active ingredients which have been introduced to the cosmetic industry in the last 40-50 years.
