What is it?

A cosmetic ‘snake peptide’ for expression-line appearance. It is not venom and not a medicine.

Mechanism of action

Proposed muscle-relaxation-look mechanism at the skin surface.

Topical cosmetic only.

What is it being studied for?

  • Appearance of expression lines

Investigational findings are not proven clinical benefits unless an authority has labelled that indication.

Evidence level

Overall human evidence grade: C · Limited or early human evidence

Human research

Evidence is mainly cosmetic or ingredient-supplier studies, not pharmaceutical Phase 3 programmes.

Preclinical research

Animal, cell and in-vitro findings are listed separately from human effects.

In-vitro and small dermal models are commonly cited by manufacturers.

Doses reported in published research

This section does not provide personalised medical dosing. Values are those reported in papers or protocols. Animal mg/kg doses are not converted to human doses.

Doses reported in human studies

Insufficient reliable evidence identified.

Preclinical / animal study dosing

Insufficient reliable evidence identified.

Pharmacokinetics

Reliable human pharmacokinetic data were not identified for this encyclopaedia entry, or are limited to product information for approved presentations.

Safety

Topical irritation is possible. Do not inject cosmetic ingredients.

Unknowns. Absence of a published harm signal is not evidence of safety.

Contraindications. Hypersensitivity to the ingredient or formulation. Not for broken skin unless a clinician directs.

Regulatory status

Cosmetic ingredient / branded cosmetic active. Not an approved systemic medicine.

Permitted in cosmetics when formulated and advertised within cosmetic rules. Cellular Sequence does not sell research-chemical injectables of these actives.
