Tetrapeptide-73 is a synthetic peptide that has garnered attention in the cosmetic industry for its skin conditioning properties. Composed of a sequence of four amino acids—specifically asparagine, serine, threonine, and tryptophan—this peptide is designed to mimic natural peptides found in the skin.
The journey of Tetrapeptide-73 into the world of cosmetics is relatively recent, driven by advancements in peptide synthesis and a growing understanding of how peptides can benefit the skin. Initially studied for its potential in medical applications, researchers soon discovered its efficacy in skin conditioning, leading to its adoption in various skincare formulations. The peptide is synthesized through a controlled chemical process that links the four amino acids in a specific sequence, ensuring consistency and purity in the final product.
Tetrapeptide-73 is manufactured using solid-phase peptide synthesis (SPPS), a method that allows for precise control over the peptide’s structure. This process involves anchoring the first amino acid to a solid resin, then sequentially adding the remaining amino acids. Each addition is followed by a series of washing and deprotection steps to ensure the correct sequence and structure. Once the peptide chain is complete, it is cleaved from the resin and purified, resulting in a high-quality ingredient ready for use in cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Tetrapeptide-73:
Tetrapeptide-73 is primarily known for its skin conditioning properties. This means that it helps to maintain the skin in good condition. In practical terms, this can translate to improved skin texture, enhanced softness, and a more even skin tone. By incorporating Tetrapeptide-73 into your skincare routine, you can expect your skin to feel smoother and look healthier over time. It works by supporting the skin’s natural functions, ensuring that it remains hydrated and resilient against environmental stressors.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Tetrapeptide-73 is generally considered safe for topical application in cosmetic products. However, as with any ingredient, there are potential side effects that users should be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Tetrapeptide-73 during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Tetrapeptide-73 are relatively uncommon, but they can occur. To minimize the risk of an adverse reaction, it is recommended to perform a patch test before widespread usage of any product containing this ingredient.
In terms of comedogenicity, Tetrapeptide-73 has a rating of 0, meaning it is considered non-comedogenic. This is beneficial for individuals who are prone to acne, blemishes, or breakouts, as it is unlikely to clog pores or exacerbate these conditions.
