Bicycloheptane Carbonitrile
INCI: 1,3-DIMETHYL-BICYCLOHEPTANE-2-CARBONITRILE
A synthetic scent ingredient that adds a fresh note but offers no skincare benefit and may be unnecessary for sensitive skin.

This is a man-made chemical added to products to give them a fresh, clean smell. It doesn't moisturize, treat, or improve your skin in any way—it's purely for fragrance. If you have sensitive skin or prefer unscented products, you might want to avoid it.
