If you’ve spent any time in advanced cosmetic formulation circles, you’ve heard the term “topical botox alternative” thrown around. Most of the time it’s marketing. Syn-Ake is the exception — a rigorously studied synthetic peptide with a genuine mechanism of action at the neuromuscular junction that makes the claim legitimate.
This guide covers everything a formulator needs to know about Syn-Ake: what it is, how it works, how to use it, and how to build it into high-performance serums that deliver real results.
What Is Syn-Ake?
Syn-Ake is the trade name for Dipeptide Diaminobutyroyl Benzylamide Diacetate — a synthetic tripeptide developed by Pentapharm (now DSM) that mimics the biological action of Waglerin-1, a neuropeptide found in the venom of the Temple Viper (Tropidolaemus wagleri).
Rather than using actual venom, Syn-Ake reproduces the key molecular mechanism responsible for Waglerin-1’s muscle-relaxing effect in a stable, synthetic, cosmetic-grade form. The result is a peptide that works at the neuromuscular junction to temporarily reduce muscle contraction — the primary driver of dynamic expression lines.
CAS Number: 823202-99-9 INCI Name: Dipeptide Diaminobutyroyl Benzylamide Diacetate Molecular Weight: 467.54 g/mol Solubility: Water-soluble
How Syn-Ake Works
To understand Syn-Ake’s mechanism, you need to understand what causes expression lines in the first place.
Every time you smile, squint, frown, or raise your eyebrows, your facial muscles contract. That contraction is triggered by acetylcholine — a neurotransmitter released at the neuromuscular junction (NMJ) that binds to nicotinic acetylcholine receptors on the muscle cell surface. Over years of repeated contractions, the skin above those muscles loses elasticity and the lines become permanent.
Botulinum toxin prevents acetylcholine from being released at the NMJ. Syn-Ake takes a different approach — it competes with acetylcholine at the receptor itself. By occupying the nicotinic receptor, Syn-Ake reduces how strongly the muscle responds to each contraction signal. The muscle still moves, but with reduced frequency and force. Over time, this translates to measurably shallower expression lines.
In Pentapharm’s clinical studies, Syn-Ake at 4% in a finished formulation demonstrated a 52% reduction in wrinkle depth after 28 days — a result that stands up to independent scrutiny.

How to Formulate With Syn-Ake
Dissolution
Syn-Ake is fully water-soluble. Dissolve in distilled or deionized water before incorporating into your formulation. It does not require a carrier solvent.
Phase Addition
Add Syn-Ake to the water phase, or during the cool-down stage below 40°C if working with an emulsion. Avoid prolonged exposure to high heat to preserve peptide integrity.
Use Level
The clinically studied range is 1%–4%. At 1%, you’ll see meaningful activity in a serum that layers well with other actives. At 4%, you’re at the concentration used in Pentapharm’s wrinkle-depth studies. Most professional formulations sit at 2%–3% as a balance between efficacy and cost.
pH Compatibility
Syn-Ake is stable from pH 4.0 to 8.0 — one of the broadest ranges of any cosmetic peptide. This makes it easy to combine with acidic actives like vitamin C derivatives or AHAs without compatibility concerns.
Building a Syn-Ake Serum: Three Approaches
1. Single-Mechanism Expression Line Serum
The simplest approach — Syn-Ake as the hero active at 2%–4% in a lightweight hyaluronic acid and pentylene glycol base. Clean, easy to market, highly effective for a targeted eye contour or forehead serum.
2. Dual-Mechanism Anti-Wrinkle Serum (with Snap-8)
Syn-Ake and Snap-8 work through complementary pathways — Syn-Ake at the receptor level, Snap-8 inhibiting SNAP-25 upstream in the signal chain. Combining both at 2% each creates a serum with two independent mechanisms of action targeting the same end result. This is the backbone of most professional-grade “botox alternative” serums.
3. Triple-Mechanism Natural Botox Alternative (with Snap-8 + Spilanthes)
Adding Spilanthes Extract (Acmella oleracea) brings a third, botanical neuromodulatory pathway. Syn-Ake at 2% + Snap-8 at 2% + Spilanthes at 0.5%–1% creates a compelling, story-rich formulation suitable for clean beauty positioning — three mechanisms, two synthetic peptides, one botanical active.
Syn-Ake Compatibility
Syn-Ake plays well with virtually every standard cosmetic active:
Excellent pairings:
- Snap-8 — dual NMJ/SNARE mechanism anti-wrinkle
- GHK-Cu — adds collagen synthesis and repair to the expression-line focus
- PDRN — tissue regeneration beneath the surface while Syn-Ake works at the muscle
- Hyaluronic acid (all molecular weights) — plumping base that enhances the smoothing effect
- Niacinamide — tone-evening and barrier support
- Spilanthes Extract — natural neuromodulator for triple-mechanism formulas
Avoid:
- High-concentration EDTA — may interfere with peptide stability
- Strong oxidizing agents at high temperatures
Who Should Be Using Syn-Ake
Indie skincare brands launching a hero anti-wrinkle serum need a clinically backed active with a compelling story. Syn-Ake delivers both — the venom-mimetic narrative resonates with consumers, and the 52% wrinkle-reduction data gives you something real to stand behind.
DIY formulators working on expression-line treatments will find Syn-Ake one of the most rewarding actives to build around — the results are noticeable, the formulation is straightforward, and it combines beautifully with other peptides.
Cosmetic chemists developing multi-peptide complexes should consider Syn-Ake as a standard component of any comprehensive anti-aging stack alongside GHK-Cu, Snap-8, and PDRN.
