less wrinkle depth after 30 days (Argireline cream)
Small 2002 study in healthy women
Cosmetic ingredients used in anti-wrinkle creams and serums. Not medicines.
What is Argireline & Snap-8?
Argireline is a lab-made peptide of six building blocks, designed to copy a small part of the machinery that Botox blocks. Snap-8 is a slightly longer version made for the same purpose.
How does Argireline & Snap-8 work?
Muscles contract when nerves release a chemical messenger. Argireline is designed to interfere gently with that release, so the small facial muscles behind expression lines relax a little. It is far weaker than Botox and isn’t injected.
What does the research show?
- In a 2002 study, healthy women who applied a cream with 10% Argireline saw wrinkle depth fall by up to 30% after 30 days.
- Snap-8 has very little published research of its own.
Known risks and side effects
- Creams are generally well tolerated; some people get skin irritation.
Is Argireline & Snap-8 approved?
Mostly studied in cells and animals, with little or no proper testing in people.
Cosmetic ingredients used in anti-wrinkle creams and serums. Not medicines.
