Meijo University and Chulalongkorn University researchers identified a natural UV-filtering molecule called β-glucose-bound hydroxy mycosporine-sarcosine (GlcHMS326), featuring both UV-absorbing and antioxidant activity. The compound was discovered in thermophilic cyanobacteria from Thailand’s Bo Khlueng hot spring and is produced only when the microbes experience combined UV and salt stress. Classified as a mycosporine-like amino acid, it offers water solubility and biocompatibility that align with demand for gentler sun care ingredients.
GlcHMS326 stands out for its trio of rare chemical modifications—glycosylation, hydroxylation, and methylation—observed together for the first time in cyanobacterial MAAs. These tweaks enhance molecular stability and strengthen free-radical scavenging compared with more common MAAs. Genetic analysis also revealed a distinct biosynthetic pathway, highlighting specialized stress-response genes that control the compound’s production.
For consumers, GlcHMS326 points toward future sunscreens and skincare lines that balance effective UV defense with reduced irritation and environmental impact. Its performance under intense UV and saline conditions makes it a strong candidate for eco-conscious “biofactory” production, supporting cleaner formulations and reef-safer SPF systems. By expanding the palette of natural UV filters, this discovery reinforces a broader shift toward bio-derived, function-first cosmetic ingredients.
