What it is
Zwitterionic betaine compound originally identified as an osmoprotectant in marine invertebrates including sea urchins and molluscs; in marine organisms it protects cells from osmotic stress and UV-induced oxidative load; proposed skin benefits include similar osmoregulatory stabilisation of keratinocytes under environmental stress, and antioxidant activity via free radical scavenging; water-soluble across all pH ranges; used in formulations targeting UV-stressed and sensitised skin; limited independent human trial data but promising in vitro antioxidant profiling.
