Palmitoyl tetrapeptide-10

Basic Description

​​​​​​​​​​Structure and function ​:
Palmitoyl Tetrapeptide-10 is a synthetic lipopeptide composed of a tetrapeptide sequence covalently linked to a palmitoyl group (C16 fatty acid). , which works through the following mechanisms:
1. ​​Barrier repair​ ​：Promote the synthesis of epidermal lipids (ceramide, cholesterol), enhance skin barrier function, and reduce transepidermal water loss (TEWL).
2. ​​Anti-inflammatory and soothing​ ​：Inhibit the release of inflammatory factors (such as IL-6, TNF-α), relieve sensitive skin and erythema.
3. ​​Anti-aging​ ​：Activate fibroblasts and indirectly promote ​Collagen Type I and ​Fibronectin​​ is generated.

​ ​Application Areas​ ​:
• ​​Cosmetics ​: Repair cream, sensitive skin care essence, post-operative repair products.
• ​In vitro studies ​：Skin barrier model and inflammatory signaling pathway regulation research.
