Fat Facts
Insights in Bio-Fermented Oils
Welcome to our blog for beauty formulators, ingredient innovators, and curious creators. We dive into the science behind microbial oils, explore the future of fermentation, and share expert insights on how bioengineered fats are shaping the next generation of clean, high-performance beauty.
At Xylome, we grow oil — not from plants or animals, but from yeast. Through fermentation and precision metabolic engineering, we create structured lipids with functionality, consistency, and traceability that beauty formulators can count on.
