A synthetic peptide that inhibits neurotransmitter release at the neuromuscular junction, reducing muscle contraction and the appearance of expression lines. Often called 'topical Botox' in marketing, though the mechanism and potency differ significantly. One of the most commercially successful cosmetic peptides.
A cosmetic peptide that mimics the N-terminal end of SNAP-25, a protein involved in neuromuscular signaling. By competing with SNAP-25 for a position in the SNARE complex, it reduces the intensity of muscle contractions that cause expression lines. Often called 'topical Botox' in the skincare industry, though its effects are much milder than injectable neurotoxins.
Mimics the N-terminal end of SNAP-25, a protein essential for SNARE complex formation and neurotransmitter vesicle fusion. By competing with native SNAP-25, it partially inhibits acetylcholine release at the neuromuscular junction, reducing the intensity of muscle contractions that cause expression wrinkles.
Competes with natural SNAP-25 for binding in the SNARE complex, which is required for neurotransmitter release at the neuromuscular junction. By partially inhibiting SNARE complex formation, it reduces acetylcholine release and softens muscle contractions that create wrinkles. Works topically — no injection required.
