I just found out that my favourite shower gel contains the products of yeast fermentation. Sounds gross! It is specifically Zink/Saccharomyces ferment and also Magnesium/Saccharomyces ferment. I reckon it is the fermentation products of the yeast Saccharomyces in the presence of those compounds.
I have never seen them in any products that I used before. But surprisingly Google says it is widely-used in cosmetic products. And furthermore it says they absorb into the skin. Probably helping with the moisturising and retaining skin moisture (?). But I noticed that the shower gel also produces more lather (bubbles) than others.
No side effects so far to me, but I would like to know more of which species of Saccharomyces that they used for that purpose. Hopefully not the cerevisiae one...
