Pentapeptide-18
A neuro-relaxing peptide that inhibits enkephalin degradation, in turn inhibiting acetylcholine release. Synergistic with Argireline — combined at 3–5% each, studies show enhanced wrinkle reduction versus either alone.
Topical 3–5% in serums or eye creams, AM and/or PM. Highly compatible with other peptides and most actives.
