Can you please talk about fermented ingredients? How are they made? I work in non-cosmetic biotech, and the ingredient names don't mean anything to me: fermentation and filtration are very broad terms, they don't even specify the species. I would assume that two products with the same ingredients can have very different compositions depending on the production parameters. So without industry insider knowlede or clinical testing we can't know if the product is doing anything, can we? Or are there regulations in place to make sure these ingredients are comparable? And does our skin really need dead bacteria and yeasts? What about fermenting plants? Does fermentation bring any additional benefits? (Are "rotten" plants better for the skin than fresh plants?😉) Out of curiosity, can genetically modified microorganisms or products of those be used in cosmetics?
Great episode, as always. A practical "slugging" question that I've never heard addressed: what do you do the next morning? Ostensibly, you're slugging because you have dry, damaged, or dehydrated skin. So you probably don't want to use a surfactant on your face in the morning (at least I don't and not doing so is often suggested as a best practice for dehydrated skin like mine). But whenever I use something with petrolatum in it, it's still there in the morning. I can't put my AM skincare over that. And obviously a straight water rinse isn't going to get rid of the residual layer. Is there a hack for this dilemma?
Very Helpfullll
