SNAP-8- Summary
- Cerebrolysin is a porcine brain-derived neuropeptide complex that mimics the action of endogenous neurotrophic factors (BDNF, NGF, GDNF, NT-3). It promotes neurogenesis, neuroprotection, and synaptic plasticity, and is approved in many countries for stroke, traumatic brain injury, and Alzheimer's disease.
- SNAP-8 is a synthetic octapeptide cosmetic ingredient that reduces the depth of expression lines and wrinkles by competitively inhibiting the SNARE complex involved in acetylcholine release at neuromuscular junctions, providing a topical 'Botox-like' effect.
- Half-Life
- Variable for the complex; individual peptide fractions: minutes to hours
- N/A — topical application; local effect duration depends on formulation
