Ascorbyl Succinoyl Tetrapeptide-21, also known as 2-O-succinoyl-glycyl-L-glutamyl-L-lysyl-glycyl-L-ascorbic acid, is a synthetic peptide that combines the benefits of ascorbic acid (vitamin C) and a tetrapeptide. This ingredient is primarily sourced from laboratory synthesis rather than natural extraction, ensuring a high level of purity and consistency. It is recognized in the cosmetic industry for its dual role as an antioxidant and skin conditioning agent.
The journey of Ascorbyl Succinoyl Tetrapeptide-21 into the world of cosmetics is relatively recent, driven by the ongoing quest for innovative ingredients that offer multiple skin benefits. The fusion of ascorbic acid with a tetrapeptide was designed to enhance the stability and efficacy of vitamin C, which is notoriously unstable in its pure form. This combination allows for better skin penetration and prolonged activity, making it a valuable addition to skincare formulations.
The manufacturing process of Ascorbyl Succinoyl Tetrapeptide-21 involves a series of chemical reactions that link the ascorbic acid molecule to a specific tetrapeptide sequence. This is achieved through a process called peptide synthesis, where amino acids are sequentially bonded together in a controlled environment. The resulting compound is then subjected to rigorous testing to ensure its safety and effectiveness before being incorporated into cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Ascorbyl Succinoyl Tetrapeptide-21:
One of the standout features of Ascorbyl Succinoyl Tetrapeptide-21 is its antioxidant properties. In simple terms, this means that the ingredient helps to neutralize free radicals—those pesky molecules that can cause damage to your skin cells. By combating these free radicals, Ascorbyl Succinoyl Tetrapeptide-21 helps to protect your skin from environmental stressors like pollution and UV radiation. This can lead to a reduction in visible signs of aging, such as fine lines and wrinkles, making your skin look fresher and more youthful.
Another key benefit of Ascorbyl Succinoyl Tetrapeptide-21 is its skin conditioning ability. This means that the ingredient helps to improve the overall appearance and feel of your skin. It can enhance skin texture, making it smoother and more supple. Additionally, it can help to maintain the skin’s natural moisture balance, ensuring that your skin stays hydrated and healthy-looking. This makes it a great addition to moisturizers, serums, and other skincare products aimed at improving skin quality.
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).
Ascorbyl Succinoyl Tetrapeptide-21 is generally considered safe for topical use in cosmetic products. However, as with any skincare ingredient, there are potential side effects and considerations to keep in mind.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Ascorbyl Succinoyl Tetrapeptide-21 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.
Side effects and adverse reactions from Ascorbyl Succinoyl Tetrapeptide-21 are generally uncommon. However, it is recommended to perform a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
In terms of comedogenicity, Ascorbyl Succinoyl Tetrapeptide-21 has a rating of 0, meaning it is considered non-comedogenic. This makes it suitable for individuals who are prone to acne, blemishes, or breakouts, as it is unlikely to clog pores or exacerbate these conditions.
