INCI Name: Acetyl Tetrapeptide-3

CAS: 827306-88-7

Molecular Formula: C₂₂H₃₉N₉O₅

A biomimetic peptide that revitalizes hair follicles by boosting cell proliferation and collagen production.

Product Information:

Hair follicles are dynamic mini-organs whose vitality depends on the proliferation of dermal papilla cells and the integrity of surrounding extracellular matrix. ReGrow-AT3 is a biomimetic peptide that stimulates the proliferation of key follicular cells and enhances the synthesis of structural proteins such as collagen types III, IV, and VII, as well as laminin. By reinforcing the anchoring structure and promoting tissue regeneration, ReGrow-AT3 effectively supports healthier, denser, and thicker hair growth. 

Efficacy:

Experiment conditions: Human dermal fibroblasts; 

Blank control: Complete cell culture medium; 

Test group: 200 ppm ReGrow-AT3, 200 ppm Minoxidil

Result: ReGrow-AT3 has a stronger ability to promote the expression of type IV and type VII collagen.

Application Fields:
