What is KPV Peptide?
Xi'an Faithful BioTech Co., Ltd. is situated in Xi'an, the birthplace of the ancient Silk Road. Leveraging the city's mature logistics network and abundant fine chemical industrial resources, our enterprise has grown into an integrated fine chemical provider that delivers products to global partners. KPV Peptide (CAS No. 67727-97-3) features the amino acid sequence L-Lysyl-L-prolyl-L-valine (Lys-Pro-Val), a molecular weight of 342.43, and appears as a white powder with excellent water solubility. Derived from the C-terminal fragment (residues 11–13) of α-MSH, this bioactive peptide retains superior bioregulatory properties while avoiding pigmentation-related effects, offering distinct application advantages. Its small-molecule structure enables excellent skin penetration, allowing it to modulate epidermal signaling pathways, soothe signs of skin discomfort, reduce redness and reactivity, and help maintain skin homeostasis.
Application of KPV Peptide
As a popular active tripeptide ingredient, KPV peptide is primarily used in the development of topical skincare products. Leveraging its signal-modulating properties, it soothes skin redness and discomfort, maintains internal skin balance, aids in repairing the skin barrier, and addresses issues such as skin fragility and intolerance, making it ideal for formulations focused on sensitive skin repair, soothing, and maintenance. Additionally, it is widely used in cell-related scientific research-including studies on skin physiological mechanisms-and can be combined with various other active skincare ingredients to enable diverse formulation systems.

Mechanism of action of KPV Peptide
Modulates cellular signaling pathways and the expression of relevant transcription factors, balances the release of various signaling molecules, and alleviates abnormal stress responses in the skin.
Reduces imbalance signals triggered by external stimuli, improves visible discomfort such as redness and a burning sensation, and soothes reactive skin.
Helps maintain the normal physiological state of epidermal cells, protects the skin barrier structure, and enhances the skin's tolerance to external irritants.
Leverages a small-molecule peptide structure to easily penetrate and act upon the epidermis, gently regulating the skin's microenvironment and promoting long-term stability.
