what the actual....?! had to look it up..
Google ai says: Hyaluronic acid (HA) used in cosmetics is primarily sourced through bio-fermentation of bacteria, rather than extraction from animal tissues like rooster combs. This process involves using lactic acid bacteria to produce HA, which is then purified and dehydrated into a powder. While some HA was historically extracted from rooster combs, this method is less common today due to ethical concerns and the availability of more sustainable alternatives
I was gonna throw out a bunch of stuff!
Seriously though..who decided to rub rooster comb slices on themselves to discover this???
