In cosmetic and dermatological research it is investigated for competing with SNAP-25 in the SNARE complex, proposed to attenuate neurotransmitter release and thereby reduce expression-line intensity; studied in topical in vitro and in vivo settings for periorbital and forehead expression-wrinkle appearance. Research applications Topical cosmetic-active dermatological research SNAP-25-mimetic / SNARE-complex signaling studies Formulation and stability research for cosmetic peptides Quality & documentation Every lot is tested by an independent third-party laboratory before it enters the catalog.
