What is Palmitoyl Tetrapeptide-7?
Palmitoyl tetrapeptide-7 is a type of synthetic peptide composed of many amino acids to reduce skin inflammation and the skin damage. This peptide is believed to stimulate the regeneration of collagen in the dermis and improve the epidermal barrier.
Benefits of Palmitoyl Tetrapeptide-7:
Peptides found in our skin trigger a signalling cascade that release matricins or collagen stimulators. This causes an increase in proliferation of collagen, elastin, proteoglycan, glycosaminoglycans and fibronectin which are essential for skin integrity and structure. A photo-damaged skin and fine lines and wrinkles reduce the regeneration of the skin cell and synthesis of essential proteins. Synthetic peptides such as Palmitoyl tetrapeptide-7 mimic the natural peptides found in the skin to increase the synthesis of collagen, elastin, proteoglycans and glycosaminoglycans, thus, developing hydrated rejuvenate skin.
Further, Palmitoyl tetrapeptide-7 suppresses the excess production of chemical messengers known as interleukins that can trigger an inflammatory response in the skin. Therefore, application of the peptide will reduce inflammation and damages caused by environmental stresses like UV rays, pollution and stress. A study showed that skin cells exposed to UV radiation and then treated with Palmitoyl Tetrapeptide-7 saw an 86% reduction of interleukin production which help decrease the appearance of wrinkles and improve skin tone and elasticity.
Side Effects & Toxicity:
An extremely safe ingredient, Palmitoyl tetrapeptide-7 has no known toxicity in general use and is shown to be non-irritating and suitable for sensitive skin.
Palmitoyl tetrapeptide-7 is commonly used in anti-aging serums, night creams and anti-wrinkle creams to remove acne scars and other pigmentation problems.
