WHERE DOES IT 
COME FROM?

Two building blocks of proteins (called amino acids), naturally found in the human body, have been assembled to create neurosensine: arginine and tyrosine. Consequently, it looks like a naturally-occurring molecule that is involved in pain regulation.

WHAT IS IT 
USED FOR?

Indeed, sensitive skin could be due to the hyperexcitability of nerve endings.
By lowering skin reactivity threshold, neurosensine helps soothing discomfort signs, such as redness, itching, tingling and heating sensations.
