A clinical study involving 50 human subjects using 4% Syn-AKE topically twice daily for 28 days demonstrated[5]: Wrinkle depth reduction of up to 52% on forehead expression lines Smoothing effect measurable in 80% of participants Wrinkle reduction evident in 73% of subjects Superior efficacy compared to acetyl hexapeptide-8 (Argireline) in head-to-head comparison Skin surface measurement studies using profilometry showed improvements in skin roughness parameters (Ra, Rz, and Rt measurements), with effects visible as early as 1-2 hours post-application continuing through 28 days of use[5]
The primary pharmacokinetic difference between the routes is therefore kinetic rather than total exposure: IM produces sharper, faster peaks while SubQ produces slower, more sustained plasma profiles
The pigmentation research profile established for injectable MT-II provides a reference baseline against which sublingual delivery outcomes can be compared in research settings
