PALMITOYL TETRAPEPTIDE-50.

Valuable / SKIN CONDITIONING

Palmitoyl Tetrapeptide-50 is a sophisticated synthetic lipopeptide engineered to enhance skin regeneration and hydration. By stimulating dermal fibroblasts, it promotes vital skin repair processes, visibly improving elasticity, density, and overall texture while reducing the appearance of fine lines and wrinkles for a revitalized complexion.

Summary

Cell-communicating Skin conditioning Hydrating Elasticity-boosting Anti-aging Skin regeneration support

Science

Mechanism of Action

This advanced lipopeptide contains biologically active Pro-Hyp (Prolyl Hydroxyproline) motifs, which are integral to collagen structure. Its primary mechanism involves stimulating dermal fibroblasts, crucial for promoting their proliferation and migration, thereby supporting wound healing and skin regeneration. It significantly boosts the production of glycosaminoglycans (GAGs), especially hyaluronic acid, by upregulating the Hyaluronan Synthase 2 (HAS2) enzyme. This action collectively leads to enhanced skin hydration, improved elasticity, reduced transdermal moisture loss, and a decrease in the visibility of fine lines, ultimately improving skin density.

Dusting Analysis

Not commonly dusted

While specific efficacy thresholds are not universally published, its common incorporation into advanced, targeted delivery systems, such as the X50® Hyalufiller complex, suggests that it is typically utilized in formulations designed for effective delivery rather than merely 'dusting' at negligible concentrations.
