Argireline

Acetyl hexapeptide-3, the topical anti-wrinkle peptide shown in laboratory work to interfere with SNARE complex formation.

Last updated: August 2026

What is Argireline?

Argireline (acetyl hexapeptide-3, also sold as Argireline by Lipotec) is a synthetic hexapeptide that was designed as a cosmetic stand-in for botulinum toxin. In laboratory work it interferes with the formation of the SNARE complex, the protein assembly a nerve ending needs in order to release its signal, and that is the same assembly botulinum toxin disables. In plain language: the mechanism measured in the lab is a partial block of the nerve to muscle signal, applied to the skin rather than injected. Whether that mechanism reaches facial muscle after topical use is a separate question, and the skin penetration study cited at the end of this page is why it stays open. It is one of the most studied cosmetic peptides and appears in hundreds of anti-aging skincare products worldwide. Browse the full peptide library for related compounds.

The honest framing: Argireline has measured effects, but it is not Botox. The 2002 paper from the team that designed the peptide reported wrinkle depth reduced by up to 30 percent over 30 days, using a 10 percent oil-in-water emulsion on healthy women volunteers. "Up to" is the ceiling in that study rather than a typical result, and the group reporting it is the group that developed the ingredient. The same paper found the peptide inhibited neurotransmitter release with a potency similar to botulinum toxin A but with much lower efficacy than the toxin, which is the honest shape of the comparison. A later randomised trial in 60 Chinese subjects reported 48.9 percent total anti-wrinkle efficacy against 0 percent for placebo, though that was a subjective global assessment rather than a depth measurement. Treat it as a mild cosmetic effect, not a needle-free Botox.

Commonly combined with GHK-Cu (collagen stimulation) and SNAP-8 (same mechanism, an octapeptide version marketed as penetrating deeper, which has not been shown). The idea behind pairing them is SNARE inhibition plus collagen stimulation, one aimed at the muscle contraction side and one at the skin structure side, and the muscle side carries the same open question about how far the peptide travels.

In Vietnam, Argireline is available research-grade from regional suppliers. Also found in some imported skincare products at Vietnamese cosmetics shops in District 1 and District 7. Not a pharmacy or hospital product. For verified suppliers, see the supply index. Verify purity via the COA guide. For legal context, see the peptide legality guide.

How It Works

SNARE Complex Inhibition: In laboratory work the peptide blocks formation of the SNARE protein complex that a nerve ending needs in order to release acetylcholine, which lowers the intensity of muscle contraction. That is what was measured in the lab, not on treated facial skin.

Wrinkle Depth Reduction: The proposed chain is that fewer muscle micro-contractions leave expression lines (forehead, crow's feet, frown lines) less pronounced over time. Reduced wrinkle depth has been measured in trials. The muscle step in between is the part that has not been shown in treated skin.

Topical Delivery: Unlike Botox which requires injection, Argireline is applied to the skin surface, and how far it travels from there is limited. In an FDA laboratory study on human skin, 0.22 percent of the applied dose stayed in the stratum corneum, about 0.01 percent reached the epidermis, and none was detected in the dermis below or in the fluid collected beneath the skin. Muscle sits below the dermis, so reaching facial muscle is not established.

Side Effects

Common

⚠Mild skin irritation in sensitive individuals

Rare

•Contact dermatitis (discontinue if rash develops)

Who Should NOT Use Argireline

✕Active skin infections or open wounds on application area
✕Known allergy to peptide ingredients
✕Pregnancy or breastfeeding (insufficient data)

What to Expect

Week 1-2

No visible change yet. The trials that measured an effect ran over weeks rather than days.

Week 3-4

Subtle softening of fine lines. Most noticeable on forehead and around eyes.

Month 2-3

Past the point where the published trials measured their results, which was 30 to 60 days on a 10 percent formulation. Any change tends to be subtle.

Long-term

Effects are maintained with continued use. They reverse within 2 to 4 weeks of stopping.

Notes from Ho Chi Minh City

Argireline is a topical that gets used in HCMC as a between-Botox bridge. The injectable itself, onabotulinumtoxinA, is a clinic procedure: District 1 dermatology practices are where people go for a forehead session, and the constraint there is appointment cadence rather than access. As a peptide cosmetic Argireline is described as maintaining part of the smoothing effect as Botox fades around month three. Retail access to it is easy by comparison: An Phu and District 7 cosmetics shops stock The Ordinary's Argireline Solution in 30ml bottles, and DIY formulations are mixed from research-grade powder brought in by cold-chain importers. Concentration and routine are personal-care choices best confirmed with a dermatologist.

Sourcing in Vietnam

Argireline (acetyl hexapeptide-3) is sold over-the-counter as cosmetic products in Vietnam, including The Ordinary Argireline Solution in 30ml bottles at imported cosmetic retailers in District 1 and District 7. Research-grade powder for DIY formulations is sourced through cold-chain importers. Not a pharmaceutical product and not stocked at Long Châu, Pharmacity, FV Hospital, or Vinmec pharmacies. See the supplier list and COA guide before purchasing.

FAQ

Q: Is Argireline as good as Botox?

A: No. The original 2002 study reported wrinkle depth reduced by up to 30 percent over 30 days at 10 percent concentration, and a randomised trial in 60 subjects reported improvement over 4 weeks on a subjective global assessment. Botox is an injected neurotoxin, and the 2002 paper itself found the peptide had much lower efficacy than the toxin at blocking neurotransmitter release. The two are described as acting on the same SNARE pathway, but an FDA study detected almost none of the peptide below the stratum corneum in human skin and none at all in the dermis, so the needle-free Botox comparison overstates what it does.

Q: Can I use Argireline with retinol?

A: Yes. Argireline is compatible with retinol, vitamin C, hyaluronic acid, and most active skincare ingredients. Apply Argireline first (water-based), then oil-based actives.

A synthetic hexapeptide (Argireline) with antiwrinkle activity · Blanes-Mira C, Clemente J, Jodas G, et al. · International Journal of Cosmetic Science (2002) (PMID: 18498523)
Original mechanistic paper describing SNARE complex inhibition, and the actual source of the wrinkle-depth figure: a 10 percent oil-in-water emulsion reduced wrinkle depth up to 30 percent over 30 days in healthy women volunteers. The same paper reports the peptide inhibited neurotransmitter release with a potency similar to botulinum toxin A but much lower efficacy than the toxin. Reported by the group that designed the peptide.
In vitro skin penetration of acetyl hexapeptide-8 from a cosmetic formulation · Kraeling ME, Zhou W, Wang P, Ogunsola OA · Cutaneous and Ocular Toxicology (2015) (PMID: 24754410)
US FDA CFSAN. A 10 percent emulsion applied to human cadaver skin in diffusion cells for 24 hours left 0.22 percent of the applied dose in the stratum corneum and 0.01 percent in the epidermis, with none detected in the dermis or in the buffer collected beneath the skin, and no metabolite anywhere. Acetyl hexapeptide-3 and acetyl hexapeptide-8 are the same molecule, the Ac-EEMQRR sequence named in the 2002 paper above, listed under PubChem CID 71587772, so this applies directly to the ingredient on this page.

It does not report a percentage reduction in wrinkle depth.
Cosmeceutical peptides · Lupo MP, Cole AL · Dermatologic Therapy (2007) (PMID: 18045359)
Review sorting cosmeceutical peptides into three categories: signal peptides, neurotransmitter-affecting peptides and carrier peptides. Argireline sits in the neurotransmitter-affecting category, by the SNARE mechanism the 2002 paper describes. The authors write that the benefits of this class may not be as rigorously tested as most FDA-regulated drugs, while adding that the evidence supporting their use is growing.

Randomised controlled study, 24 healthy volunteers across four arms over 60 days, one of them on acetyl hexapeptide-3 alone. Measured skin microtopography and transepidermal water loss. The authors conclude the results confirm antiwrinkle activity for acetyl hexapeptide-3, and state that how the two peptides might act together was not clear in this study.
