Can synthetic biology offer a more sustainable way to bring "natural" cosmetic ingredients to market? Can a branch of bioscience that includes the word synthetic in its name ever be considered natural? These are questions Formula Botanica CEO and podcast host Lorraine Dallmeier tackles in this opinion episode. Following her interview in the previous episode with Jake Wintermute, developer-evangelist at synthetic bioscience company Ginkgo Bioworks, Lorraine picks up on some valid comments and concerns of Green Beauty Conversations’ listeners. Our recent episode with Dr Barb Paldus on biotech beauty – or lab-grown skincare – proved similarly controversial. Lorraine asks us to think carefully before we dismiss synbio and similar advances in biosciences as the anathema to natural cosmetics. Each of us must make up our own mind on these new frontiers in cosmetic science, and dig deep before deciding on what natural means to us. Listen in for a thought-provoking Green Beauty Opinion which might leave you with even more questions to answer.
