Six types of cosmetic peptide and their anti-aging effects

Among the many anti-aging ingredients, peptides stand out for their versatility and adaptability. As a stable, low-irritating ingredient that does not cause cumulative harm, peptides are suitable for almost all skin types, without the need to protect from light, without gradual acclimatization, and can be used with confidence even during pregnancy and breastfeeding.   

Here are six common peptide types and their anti-aging effects:
Acetylhexapeptide-8 (achylelin) is an oligopeptide that mimics the N-terminus of the SNAP-25 protein with 6 amino acids, often referred to as botulinoid. It is one of the commonly used ingredients in high-end cosmetics, and its main function is to reduce wrinkles caused by facial expression muscle contraction, especially on the forehead and eye area. In addition, achyrelin can also promote collagen synthesis and help rebuild skin tissue.

Tetrapeptide-1: It has antioxidant properties, can slow down skin aging, improve skin elasticity and firmness, and make the skin more moisturized and smooth.

Palmitoyl tetrapeptide-7 is a synthetic peptide composed of four amino acids. It can promote the synthesis of laminin type IV and V and type II collagen, thereby enhancing the support of collagen and elastin on the skin, improving skin elasticity, and preventing wrinkles and sagging.

Tripeptide-10 citrulline, also known as seritin, is a novel tetrapeptide protein that compensates for the decline in fibroblast function caused by aging. It acts like a core proteoglycan by ensuring the consistency of fibril diameter and spatial structure, affecting collagen regulation, and promoting the formation of collagen microfibers, thereby improving the stability of glial fibers. Tripeptide-10 citrulline is obtained by modifying tripeptide-10, which helps restore and maintain the integrity and softness of the skin after being added to cosmetics, and maintains the skin's high moisture retention, making the skin more tender and elastic, while improving the skin's firmness.

Hexapeptide-11: It acts on fibroblasts in the dermis to promote the synthesis of collagen, elastin and extracellular matrix components, thereby helping the skin achieve its ideal structure, while activating the skin's natural repair cycle, reducing fine lines and wrinkles, resisting skin sagging, and making the skin firmer and more elastic.

Tripeptide-1 is a matrikine signal peptide that mainly acts on the dermis and can promote the synthesis of extracellular matrix, including type I and II collagen, elastin, laminin, and fibronectin, thereby strengthening the structure of the dermis and making the skin thicker and firmer.

Additionally, these peptide serums combine anti-aging ingredients such as bosein, adenosine, and ginseng root extract to combat wrinkles and sagging skin through various mechanisms. It is truly a must-have essence for anti-aging at home!
