Oligopeptide-2

Also known as: Oligopeptide-2, EGF-like Peptide, Epidermal Growth Factor Peptide

All skin types

What It Is

A short synthetic peptide that mimics the activity of Epidermal Growth Factor (EGF). Used in skincare and hair care for its potential to support cell renewal and follicle activity.

What It Does

May stimulate cell renewal and growth factor signaling pathways. In lash/brow serums, targeted toward supporting the hair follicle growth environment.

Best For

Lash and brow follicle supportCell renewal signaling

Benefits

  • EGF-receptor targeting approach for follicle stimulation
  • Short peptide chain — good stability and penetration

When to Be Careful

  • EGF-like activity from topical peptides is debated — receptor binding in intact skin is not straightforward
  • Often used as a supporting ingredient rather than the primary active

Why This Gets Hype

EGF has strong clinical data in wound healing contexts. Cosmetic peptides that mimic EGF activity attract attention for anti-aging and hair growth applications.

What People Often Misunderstand

Topical EGF peptides do not behave identically to growth factor injections or wound-healing applications. The skin barrier limits penetration, and cosmetic concentrations are lower than research contexts.

Best Routine Slot

As part of a lash/brow serum applied twice daily, or as part of an anti-aging serum in PM routine.

Good Match For

Myristoyl Pentapeptide-17, Biotinoyl Tripeptide-1 in lash/brow context; collagen peptides in anti-aging context

Proceed Carefully If…

Very rare — generally well tolerated.

Signs You May Be Overdoing It

Not a known irritant at cosmetic concentrations.

FAQs About Oligopeptide-2

What does oligopeptide-2 do in lash serums?
It mimics EGF (epidermal growth factor) activity, targeting cell renewal signaling in the hair follicle environment. It works as a supporting peptide alongside more targeted lash-specific peptides like Myristoyl Pentapeptide-17.
