About EGF
Binds EGFR (EGF receptor / ErbB1), activating RAS/MAPK and PI3K/Akt signaling cascades. Promotes keratinocyte and fibroblast proliferation, accelerates wound re-epithelialization, and stimulates collagen and hyaluronic acid production.
A 53-amino acid protein that potently stimulates cell proliferation and differentiation in epithelial and fibroblast cells. Widely used in aesthetic medicine for wound healing, skin regeneration, and post-procedure recovery. One of the most established growth factors in cosmetic dermatology.

About PTD-DBM
Contains a protein transduction domain enabling intracellular delivery. Disrupts Dishevelled-Axin protein interaction, preventing β-catenin degradation and activating Wnt target genes essential for hair follicle cycling and new follicle neogenesis.
A cell-penetrating peptide that activates Wnt/β-catenin signaling in hair follicle dermal papilla cells. Studied as a potential hair regeneration therapy acting through a mechanism distinct from minoxidil and finasteride.
