KPV is a naturally occurring tripeptide composed of the amino acids lysine (K), proline (P), and valine (V). It is derived from the alpha-melanocyte-stimulating hormone (α-MSH) and is recognized for its anti-inflammatory and antimicrobial properties. KPV has been studied for its potential applications in treating inflammatory skin conditions, such as psoriasis and atopic dermatitis, due to its ability to modulate immune responses and reduce inflammation. Additionally, KPV may help in promoting wound healing and could have protective effects on the skin barrier. Research is ongoing to fully understand its therapeutic potential and mechanisms of action.
