About

A potent neurotoxin, not a normal skincare active, and completely out of line with a high safety rating.

Neosaxitoxin is a potent marine neurotoxin related to the saxitoxin family and carries an H300 fatal-if-swallowed classification in the supplied hazard data. A substance with that level of acute toxicity does not fit the safety profile expected of routine cosmetic ingredients, so it merits an extremely low score.
