lysine HCI

An amino acid salt that may be animal-derived or made in a lab (Paula’s Choice uses the latter type). Like all amino acids and derivatives, lysine HCI plays a role in keeping skin hydrated by aiding the balanced transport of water through skin’s layers.

Lysine also plays a role in helping skin produce supportive substances that keep it looking smooth and youthful.
