Ascorbic Acid Polypeptide, also known as L-Ascorbic acid, reaction products with protein hydrolyzates, is a unique cosmetic ingredient that combines the benefits of Vitamin C with the stabilizing properties of polypeptides. This ingredient is derived from the reaction of L-Ascorbic acid (a form of Vitamin C) with protein hydrolyzates, which are proteins broken down into smaller peptides and amino acids. This combination results in a more stable and bioavailable form of Vitamin C, making it an attractive option for skincare formulations.
The use of Vitamin C in skincare dates back several decades, primarily due to its potent antioxidant properties and its role in collagen synthesis. However, pure Vitamin C (L-Ascorbic acid) is notoriously unstable and can degrade quickly when exposed to light, air, and heat. To overcome this challenge, scientists developed Ascorbic Acid Polypeptide, which offers enhanced stability and efficacy. This innovation has allowed cosmetic formulators to harness the full potential of Vitamin C without the common drawbacks associated with its instability.
The production of Ascorbic Acid Polypeptide involves a chemical reaction where L-Ascorbic acid is combined with protein hydrolyzates. This process not only stabilizes the Vitamin C but also enhances its ability to penetrate the skin, ensuring that users can reap the maximum benefits. The resulting compound is a versatile ingredient that can be found in various skincare products, including serums, creams, and lotions, aimed at providing antioxidant protection and improving skin texture and tone.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Ascorbic Acid Polypeptide:
Ascorbic Acid Polypeptide is known for its antioxidant properties. In simple terms, this means it helps to protect your skin from damage caused by free radicals. Free radicals are unstable molecules that can cause oxidative stress, leading to premature aging and other skin issues. By neutralizing these harmful molecules, Ascorbic Acid Polypeptide helps to maintain the skin’s youthful appearance and overall health.
Another key benefit of Ascorbic Acid Polypeptide is its ability to condition the skin. This means it helps to improve the texture and appearance of your skin, making it feel softer, smoother, and more hydrated. It can also help to enhance the skin’s natural barrier, which is essential for maintaining moisture and protecting against environmental aggressors.
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).
Ascorbic Acid Polypeptide is generally considered safe for topical application in cosmetic products. However, like any skincare ingredient, it may cause side effects in some individuals. Here are some potential side effects to be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Ascorbic Acid Polypeptide during pregnancy 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 Ascorbic Acid Polypeptide are relatively uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
Ascorbic Acid Polypeptide has a comedogenic rating of 1, which means it is considered to be very low on the scale of pore-clogging potential. This makes it generally suitable for individuals prone to acne, blemishes, or breakouts, as it is unlikely to contribute to these issues.
