About
A toxin-inspired synthetic peptide, not a standard moisturizer or barrier support ingredient. Its pharmacology is the main story here.
S-Mu-conotoxin CnIIIC is a synthetic version of a snail toxin peptide with neuromuscular activity in its source biology. Even if topical absorption is limited, that origin and pharmacology create a level of uncertainty that is far outside the comfort zone for ordinary cosmetic peptides.
Function
Known concerns
- Highly bioactive toxin-derived peptide
- Very limited long-term cosmetic safety data
