EGF (sh-Oligopeptide-1)

INCI: sh-Oligopeptide-1 

Category: Growth Factor Peptide / Cell-Renewal Active / Wound-Healing Support 

Used in: Advanced anti-ageing serums, post-procedure recovery formulas, repair treatments.

Typical Usage Level (Topical): 10-100 ppm in formulations (active at very low concentrations)

What This Ingredient Does

EGF (Epidermal Growth Factor) is a naturally occurring signalling protein that binds to the epidermal growth factor receptor (EGFR) on keratinocytes and fibroblasts. This receptor binding activates intracellular signalling cascades that drive cell proliferation, migration, and differentiation. In practical terms, EGF accelerates the replacement of aged or damaged skin cells, speeds wound closure, and stimulates fibroblast activity for collagen and extracellular matrix synthesis. In cosmetics, sh-Oligopeptide-1 is the lab-synthesised version of human EGF, produced via biotechnology to avoid the ethical and safety issues of human-derived growth factors. Its potency at very low concentrations and its role in post-procedure recovery where the skin's barrier is compromised and cell renewal rate is critical making it a clinically significant ingredient in advanced anti-ageing formulation.

Key Benefits

• Binds EGFR to directly stimulate keratinocyte and fibroblast proliferation

• Accelerates skin cell turnover and wound healing clinically relevant in post-procedure skin

• Supports collagen and extracellular matrix synthesis vital for skin elasticity 

• Improves skin texture, density, and the visible appearance of fine lines with consistent use

• Active at very low concentrations, potency does not require high percentage use

Who It's Best For

• Post-procedure skin following laser, microneedling, chemical peels, or dermabrasion

• Mature skin (45+) with significant cell renewal slowdown and reduced fibroblast activity

• Those seeking a growth factor-based approach to anti-ageing as an alternative or complement to retinoids

• Not recommended for those with a personal or family history of hormone-sensitive cancers without oncological guidance growth factor stimulation warrants caution in this context

Clinical Note by Dr. Su

EGF is one of the most potent cell-renewal activities available in cosmetic formulation, but it comes with a clinical caveat: growth factor stimulation should not be used indiscriminately. For healthy ageing skin and post-procedure recovery, the evidence is strong and the benefit is clear. For patients with a history of certain cancers, I recommend medical consultation before use. Stability and delivery method also matter significantly EGF degrades readily; look for products with cold-chain storage or encapsulated delivery systems.
