Leuphasyl Peptide and Wrinkles

by Dr. Usman | Aug 1, 2022 | Research

Leuphasyl is the synthetic equivalent of enkephalins, which are endorphin peptides that regulate nociception. The peptide may also affect mood/behavior, movement, neuroendocrine functions, and pain perception.[2]

The peptide has been suggested to block electrical impulses at the neuromuscular junction, the synaptic space between a motor nerve terminal end and a muscle. Consequently, Leuphasyl may reduce muscular contraction, reducing instances of wrinkle development on the skin structure. Leupahsyl has been reported in research findings to potentially mitigate wrinkle development by 28% to 34.7% in animal models.[1] More specifically, the scientists suggest that “Our results emphasize that only for Leuplasyl 2% there are important ameliorations. The size of the wrinkles trajectory was smaller with the following average: 34.7% for frontal region…; 28.4% for periorbital zone.”

Leuphasyl (Pentapeptide-18) appears to attach enkephalin receptors to nerve cells, releasing acetylcholine into the synaptic gap. Leuphasyl may induce Ach release by modulating synaptic vesicle fusion directly. Following the release of Ach, Leuphasyl may bind to Ach receptors and induce muscle cramps, at which point Pentapeptide-18 enters the picture to inhibit the reaction. It is unclear if or how Pentapeptide-18 accomplishes this, but it has been suggested to function to reduce the prevalence of wrinkles around corrugator supercilii muscle and the preorbital zone while interfering with neuromuscular signaling.

An experiment by Dr. Howard Maibach, a Professor of Dermatology at the University of California, suggested that after 28 days of exposure to the peptide, 5% of Leuphasyl singularly reduced 11% of wrinkles. In addition, 5% Leuphasyl combined with 5% Argireline reduced wrinkles by approximately 25% on average, rounding up to a 45% average.

The mean wrinkle reductions for Leuphasyl, Argireline, and their combination were 11.64%, 16.26%, and 24.62%, respectively.[5] The scientists report that “This study suggested a synergistic effect between Leuphasyl and Argireline.” In this context, Leuphasyl may act to prevent the formation of wrinkles, while the attached molecules—GHK-cu and Argireline—may help reduce the lines that form.

What Does NAD+ Research Suggest?

1. Anti-Aging Potential of NAD+ Mitochondria is the powerhouse of the cells. It controls processes that generate ATP, which is a form of energy currency. In addition, it is considered to help in several intracellular signaling processes and regulates innate immunity. Mitochondria senescence may lead to decreased cellular metabolism, heightened inflammation, and accelerated cell aging. These processes may lead to certain conditions which have been linked to age-related physiological decline, and it may also induce organ dysfunction and altered tissue repair processes in cases of injury or damage. Processes that can modulate or accelerate the actions of mitochondria may reverse the biological clock. Researcher speculate that NAD+ may be a critical component of mitochondrial function. A decline in the levels of NAD+ has been suggested to interrupt signaling pathways to the nucleus by promoting a pseudohypoxic state. These changes may undergo reversal with adequate supplementation of NAD+. NAD+ supplementation has been hypothesized to mitigate or reverse decline in mitochondrial action. NAD+ supplementation may lead to the activation of SIRT1. SIRT1 is a gene that produces an enzyme called Sirtuin-1. It is also known as NAD+-dependent Deacetylase Sirtuin-1. Sirtuin-1 acts as a co-mediator for cellular processes. These may include improved metabolism, cellular longevity, and reduced inflammation. 2. Neurodegenerative Conditions NAD+ released by the nerve endings acts as a signaling molecule. Due to its antioxidant, anti-inflammatory, and regenerative potential, it has been hypothesized to exhibit significant neuroprotective characteristics. NAD+ appears to act on the mitochondrial energy generation pathways and reduces the production of Reactive Oxygen Species (ROS). ROS are toxic molecules that lead to the generation of biologically healthy molecules. ROS increases significantly over time and is considered to be a pathogenic process in the onset of age-related conditions. Findings in animal models of Parkinson’s disease suggest that NAD+ supplementation may potentially reduce ROS. It also may improve the survival of dopamine-producing cells in the brain. Researchers report that it appeared to effectively reduce the motor deficits seen in the animal models of Parkinson’s disease. 3. Muscle Function: Muscle cell proliferation is considered to decline over time as well. This decline appears to be a direct consequence of mitochondrial dysfunction and NAD+ decline. A fall in mitochondrial gene expression may lead to reduced oxidative phosphorylation. A decrease in oxidative phosphorylation may lead to reduced energy production by mitochondria. Animal research suggests that NAD+ supplementation may potentially help improve gene expression and energy generation. NAD+ supplementation appears to help stabilize the activity of Peroxisome Proliferator-activated Receptor Gamma Coactivator 1-alpha (PGC-1-alpha). Stabilization of this gene may effect muscle growth similar to regular physical activity. Also, increased oxidative stress and inflammation may potentially induce a decline in muscle mass. NAD+ supplementation may potentiate an improvement in the survival of muscle fibers. 4. NAD+ and Inflammation Nicotinamide phosphoribosyltransferase (NAMPT) is an enzyme-linked to inflammation. Several cancers are considered to lead to an over-expression of this enzyme. It is also linked to type 2 diabetes, Non-Alcoholic Fatty Liver Disease (NAFLD), and obesity. NAD+ supplementation may potentially cause a dramatic decline in the levels of NAMPT.

Research in Wrinkle Reduction and Vialox

by Dr. Usman | Sep 23, 2022 | Research Vialox peptide has been suggested to interfere with nerve and muscle signal transmission. Signals are transmitted in normal conditions after nerves release acetylcholine from their axons. Contraction may occur after acetylcholine transportation through the neuromuscular junction and binds to a receptor on the muscle. Vialox peptide may halt contraction by binding to the AChR.[2] Acetylcholine is prevented from binding due to this action, which may induce less binding and fewer muscle contractions. At the neuromuscular junction, sodium ion release is constrained due to acetylcholine binding to a muscle receptor. Depolarization occurs, which may cause electrical pulses to develop wrinkling and creasing via the muscle contraction. Vialox may inhibit this process by binding to AChR. Vialox peptide inhibits acetylcholine binding when it binds to AChR. Vialox peptide has been suggested to only affect peripheral AChRs and may not affect central neuronal receptors. Unlike the other nicotinic acetylcholine receptor antagonists. This process suggests that Vialox only acts on the neuromuscular junction. Vialox peptide may potentially reduce skin texture in research cases by up to 11% and relief by 8%, according to one study. Since wrinkle size and ease are considered to be inversely proportional, Vialox may potentially reduce wrinkle development by an average of 8%. Approximately 60% and 47% of the animal subjects were studied. Vialox (Pentapeptide-3V), composed of lysine, threonine, and serine, is considered to stimulate collagen production while tightening the skin by acting directly on the dermis. Vialox may potentially boost melanin production, a considered protectant against UV damage. Disclaimer: The products mentioned are not intended for human or animal consumption.
