Science & Benefits

Tetrapeptide-30 is a skin-brightening peptide composed of Proline, Lysine, Glutamic Acid, and Lysine. It functions by inhibiting the expression of tyrosinase and reducing the transfer of melanin to the surface. As a humectant, it provides weightless moisture that stabilizes the skin barrier. It is entirely non-comedogenic. For those with acne, it is a strategic preventative active that ensures inflammatory breakouts do not transition into long-lasting post-inflammatory hyperpigmentation (PIH), all while providing a non-clogging hydration reservoir.
