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 Leuphasyl
Tetrapeptide that mimics enkephalin to modulate facial muscle contraction; competes with enkephalin for opioid receptor sites in neuromuscular junctions; reduces repetitive muscle micro-contractions
A neuromodulating peptide that reduces expression lines via the enkephalin pathway, distinct from SNARE-inhibiting peptides (Argireline, SNAP-8). Complements those actives through a different mechanism.
