Using Prebiotics and Postbiotics in Creams?

What has been your experience using prebiotics (like oligosaccharides) and/or postbiotics (like bacterial lysates) in lotions and creams?

Do you like using any particular prebiotic and/or postbiotic ingredients in lotions and creams?

Do postbiotics produce an odor?

Any comments and discussion about prebiotic and postbiotic branded and/or generic ingredients would be greatly appreciated.

Thanks!

  • I see these as strictly marketing ingredients that shouldn't be expected to have any noticeable effect on performance. What you use depends on the story that you want to tell.

    The science behind the skin microbiome is not advanced nearly far enough for anyone to have any idea of what ingredients should be used or even what mix of microbes we would want on a person's skin. Marketing is way ahead of the science here.
  •  Agreeing with Perry... but if a client requests something like that in the product at 1% so I have to comply. :D


    I have used lactobacillus lysates before at 1% in a thin emulsion and there is a bit of an odor. Nothing that hits you in the face upon use, but if you stick your head into the bulk and take a sniff you'll get it. Ideally you'd be putting these ingredients in at 0.1% and then you wouldn't have a problem. There is also an issue of solubility, I've had some precipitate in some of the thin formulas containing the lysates. Not in every experiment, but in one or two. Again, this is less of an issue if you stick to "claims" levels.
