What-it-does: skin brightening


A four amino acid peptide (Proline – Lysine – Glutamic Acid – Lysine; PKEK) whose main magic power is to fade hyperpigmentation (aka age spots) and even out the skin tone

According to its German manufacturer, Tetrapeptide-30 has a nice anti-inflammatory function that leads to a dual action in hindering the pigmentation process. It acts as a tyrosinase inhibitor (the famous enzyme needed to create melanin), and it also blocks the transfer of the melanin up into the top layers of the skin. 

The manufacturer has done several clinical studies to back up its claims and examined what Tetrapeptide-30 is doing on Caucasian, Asian as well as on ethnic skin. The results confirmed skin-brightening, reduction of age spots, reduction of skin redness and even some reduction of acne lesions. In the reduction of age spots, the peptide showed some synergistic effects with the nice vitamin-C derivative, called SAP
