Neurotransmitter inhibitor peptides are small molecule peptides that regulate neuromuscular activity by inhibiting neurotransmitter release or blocking neural signal transmission. These peptides primarily mimic the mechanism of botulinum toxin by inhibiting the synthesis of SNARE receptors, thus preventing the excessive release of catecholamines and acetylcholine in the skin. This local blocking of neural signals responsible for muscle contraction relaxes facial muscles, effectively smoothing fine lines. Therefore, neurotransmitter inhibitor peptides are particularly suitable for areas with concentrated facial expression muscles, such as the corners of the eyes, face, and forehead.

Explore Our Full Range of Neurotransmitter Inhibitor Peptides
The application of cosmetic peptides is mainly in cosmetics and medical beauty. However, unmodified natural cosmetic peptides have poor transdermal delivery, low bioactive stability, and are easily degraded, limiting their application. This is a challenge for formulators. Therefore, our researchers innovate through structural modification, sequence optimization, and carrier encapsulation to overcome the inherent limitations of peptide molecules.

In the fields of medical aesthetics and cosmetics, neurotransmitter inhibitor peptides are gaining popularity due to their excellent anti-wrinkle, firming, and anti-aging effects. By inhibiting neural signal transmission and reducing facial muscle contractions, they achieve effects similar to botulinum toxin but are milder and free of side effects. The common application advantages include:
Effectively reduces expression lines and fine lines, resulting in smoother and more delicate skin.
Delays muscle movements by inhibiting neurotransmitter release, maintaining a youthful appearance.
Small molecular weight facilitates easy absorption by the skin, ensuring good bioactivity.
Compared to traditional botulinum toxin, these peptides are non-toxic, have no side effects, and are milder.
They act precisely on target sites within skin cells.
Even at extremely low concentrations, they deliver significant cosmetic benefits, typically added at a few ppm to a few hundred ppm in skincare products.
Widely used as effective anti-wrinkle and firming agents in skincare products such as serums, creams, and eye treatments.
Applied in the research and development of drugs for neurological regulation and pain relief.
Utilized as inhibitors or modulators in neurotransmitter pathway studies, widely used in neuroscience research.
Incorporated as bioactive peptides in functional foods for anti-aging and health benefits.
Neurotransmitter inhibitor peptides are active ingredients that regulate neural signal transmission and are commonly used in skincare products. They work by inhibiting the release of neurotransmitters such as acetylcholine, reducing muscle contraction, thereby smoothing the skin and diminishing dynamic wrinkles (e.g., expression lines). Common ingredients include Acetyl Hexapeptide-8 (Argireline), which mimics the action of botulinum toxin to help delay signs of aging, resulting in firmer and smoother skin.
Neurotransmitter inhibitors are substances that can block or reduce the release or action of neurotransmitters. By interfering with neural signal transmission, they regulate the function of the nervous system. In medicine, these substances are often used to treat neurological disorders such as depression, anxiety, or epilepsy. In skincare, they reduce muscle contractions to minimize wrinkle formation, achieving anti-aging effects.
Peptides are short-chain molecules composed of amino acids linked by peptide bonds, playing diverse physiological roles in organisms. Neuropeptides are a special type of peptide that primarily act as neurotransmitters or neuromodulators, involved in neural signal transmission. General peptides may have various functions (e.g., anti-inflammatory, repair), while neuropeptides are more focused on regulating neural activity, influencing emotions, pain perception, and more. Despite differences in structure and function, both are classified as bioactive molecules.
