Description

KPV is a three-amino-acid peptide studied for inflammation, gut health, immune response, and skin conditions. It forms part of alpha-MSH, a hormone involved in inflammatory signaling.

KPV is a tripeptide made of three amino acids: lysine (K), proline (P), and valine (V). It is the C-terminal fragment of alpha-MSH (alpha-melanocyte-stimulating hormone), a naturally occurring hormone with anti-inflammatory activity.

KPV keeps the short amino-acid sequence associated with alpha-MSH’s anti-inflammatory activity without its pigment-producing action. Oral, topical, injectable, and nasal products use that small size in different ways.

Benefits and uses

KPV research and reported use center on inflammation in three areas:

• Gut healing and inflammatory bowel conditions. In a cell and mouse colitis study, KPV entered intestinal cells through the PepT1 transporter and reduced inflammatory signaling. Oral KPV also reduced inflammation in two mouse models.
• Immune modulation. It downregulates inflammatory signaling broadly, which is why it is studied as a general anti-inflammatory rather than for one tissue alone.
• Skin inflammation. Laboratory work includes human keratinocytes and three-dimensional skin models. A 2025 study examined oxidative stress, inflammatory signaling, and cell survival after particulate exposure.

People using KPV report changes in digestive comfort, skin redness, irritation, and recovery-related inflammation. Those experiences explain why different oral and topical products exist. Human treatment trials have not yet defined how reliably those outcomes occur.
