Hexapeptide-3, also known as Acetyl Hexapeptide-3 or Argireline, is a synthetic peptide primarily used in skincare products for its anti-aging properties. It is known for its ability to reduce the appearance of wrinkles and fine lines by mimicking the effects of Botox, inhibiting muscle contraction. Hexapeptide-3 is commonly found in serums, creams, and anti-aging treatments designed to improve skin elasticity and diminish visible signs of aging.

Chemical Composition and Structure

Hexapeptide-3 is a sequence of six amino acids (hexapeptide) that works by interfering with the neurotransmitters that send signals to muscles, thus reducing facial muscle contractions that cause wrinkles. This peptide structure is designed to be easily absorbed by the skin, making it effective in combating visible signs of aging.

Physical Properties

Hexapeptide-3 typically appears as a white, water-soluble powder that can be easily incorporated into aqueous formulations like serums and lotions. It is stable and compatible with a wide range of ingredients, making it ideal for use in combination with other active anti-aging ingredients.

Production Process

Hexapeptide-3 is synthetically produced through peptide synthesis techniques, where amino acids are assembled to form the hexapeptide chain. The production process is carefully controlled to ensure the purity and effectiveness of the peptide, making it suitable for use in cosmetic formulations.

Applications

Anti-Aging Treatments: Hexapeptide-3 is mainly used in anti-aging treatments for its ability to reduce the appearance of wrinkles and fine lines, especially around the eyes and mouth. It is often referred to as a non-invasive alternative to Botox.
Serums and Creams: This ingredient is commonly incorporated into serums and skincare creams, where it is absorbed to improve skin elasticity and reduce the appearance of wrinkles.
Eye Contour Products: Due to its ability to reduce fine lines, Hexapeptide-3 is frequently used in eye contour products to treat expression lines and signs of aging.
Lifting Creams: It is included in lifting creams and lotions to improve skin firmness and provide a younger, smoother appearance.

Cosmetics - INCI Functions

Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.

Environmental and Safety Considerations

Hexapeptide-3 is considered safe for use in cosmetic products. It is generally well-tolerated by the skin, though some individuals with particularly sensitive skin may experience irritation. There are no significant environmental concerns associated with the use of this peptide, and it is used in safe concentrations in cosmetic formulations.

Abstract. Antimicrobial peptides (AMPs) are distributed across all kingdoms of life and are an indispensable component of host defenses. They consist of predominantly short cationic peptides with a wide variety of structures and targets. Given the ever-emerging resistance of various pathogens to existing antimicrobial therapies, AMPs have recently attracted extensive interest as potential therapeutic agents. As the discovery of new AMPs has increased, many databases specializing in AMPs have been developed to collect both fundamental and pharmacological information. In this review, we summarize the sources, structures, modes of action, and classifications of AMPs. Additionally, we examine current AMP databases, compare valuable computational tools used to predict antimicrobial activity and mechanisms of action, and highlight new machine learning approaches that can be employed to improve AMP activity to combat global antimicrobial resistance.

Abstract. Peptides, as a large group of molecules, are composed of amino acid residues and can be divided into linear or cyclic peptides according to the structure. Over 13,000 molecules of natural peptides have been found and many of them have been well studied. In artificial peptide libraries, the number of peptide diversity could be up to 1 × 1013. Peptides have more complex structures and higher affinity to target proteins comparing with small molecular compounds. Recently, the development of targeting cancer immune checkpoint (CIP) inhibitors is having a very important role in tumor therapy. Peptides targeting ligands or receptors in CIP have been designed based on three-dimensional structures of target proteins or directly selected by random peptide libraries in biological display systems. Most of these targeting peptides work as inhibitors of protein-protein interaction and improve CD8+ cytotoxic T-lymphocyte (CTL) activation in the tumor microenvironment, for example, PKHB1, Ar5Y4 and TPP1. Peptides could be designed to regulate CIP protein degradation in vivo, such as PD-LYSO and PD-PALM. Besides its use in developing therapeutic drugs for targeting CIP, targeting peptides could be used in drug's targeted delivery and diagnosis in tumor immune therapy.
