Identity
a synthetic cosmetic dipeptide engineered to mimic Waglerin-1, a neuromuscular-blocking toxin from snake venom — reframed as a needle-free, topical "Botox-like" wrinkle-relaxing active. It's a legitimate, widely-used cosmetic ingredient (not a drug, not an injectable), supplied by dsm-firmenich and formulated into serums/creams at low percentages.
Mechanism (as proposed)
at the neuromuscular junction, nerves release acetylcholine, which binds the muscle nicotinic acetylcholine receptor (mnAChR) to open channels, let Na⁺ in, depolarize the muscle, and trigger contraction. Syn-Ake's active dipeptide is a reversible antagonist of this receptor — modeled on Waglerin-1's selective block of the receptor's ε (epsilon) subunit — so it competes with acetylcholine, reduces Na⁺ influx and depolarization, and thereby dampens the micro-contractions of facial mimic muscles. Fewer repeated contractions → relaxed, smoothed expression lines. It's conceptually the same target logic as Botox (both quiet the nerve-to-muscle signal) but by a different, reversible, receptor-level mechanism, delivered topically rather than injected — which is why it's gentler and more gradual.
