Overview
A lipidated cosmetic peptide often included in multi-ingredient matrix-support products.
A cosmetic ingredient, not an FDA-approved anti-aging drug. Cosmetic marketing and ingredient safety reviews do not establish injectable safety or therapeutic approval.
A blend's result cannot reveal this ingredient's individual contribution.
Why It's Being Studied
- Skin inflammation research
- Matrix support
Mechanism of Action
It is proposed to modulate inflammatory signalling in skin research.

Background: Skin & Hair Research
Skin and hair research looks at collagen synthesis, wound closure, pigmentation and the hair-follicle cycle.
Topical cosmetic research is often industry-funded and small. Injected use of cosmetic peptides has little human data.
Research Areas & Routes Studied
- Skin inflammation research
- Matrix support
- Topical cosmetic formulations

Evidence limitations
- Most claims concern laboratory findings or combination products rather than independent standalone clinical effects.
Reported Adverse Events in Research
- Local irritation can occur; reviewed cosmetic exposure is not evidence for systemic use.
Limitations of Current Evidence
- A blend's result cannot reveal this ingredient's individual contribution.
- Findings apply to the product, route and population studied; they do not establish benefits or safety for unrelated wellness uses or research-vial products.
How to Read This Research
- Was the product topical or injected?
- Were results measured by instruments or by photos and self-assessment?
- Who funded the study?
- Cosmetic claims face a lower evidence bar than medical claims.
- Pigmentation-affecting compounds carry documented risks, including changes in moles.
- Anagen
- The active growth phase of a hair follicle.
- Dermis
- The skin layer beneath the surface that holds collagen.
- Melanocortin
