Yeast polysaccharides, also known as yeast-cell-wall polysaccharides, are complex carbohydrates derived from the cell walls of yeast. These polysaccharides are primarily composed of beta-glucans, mannans, and other sugar molecules that are intricately linked together. In the realm of cosmetics, yeast polysaccharides are valued for their multifunctional properties, including film forming, skin conditioning, skin protecting, and viscosity controlling.
The use of yeast and its derivatives in skincare isn’t a new phenomenon. Historically, yeast has been utilized in various cultures for its health benefits, and its application in skincare can be traced back to traditional beauty practices. However, it wasn’t until more recent scientific advancements that the specific benefits of yeast polysaccharides were fully understood and harnessed for cosmetic formulations.
The production of yeast polysaccharides involves a meticulous extraction process. Initially, yeast cells are cultivated under controlled conditions. Once the yeast has grown sufficiently, the cells are harvested and subjected to a series of treatments to break down the cell walls and release the polysaccharides. These polysaccharides are then purified and processed into a form that can be easily incorporated into cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Yeast Polysaccharides:
Yeast Polysaccharides are known for their film-forming properties. This means they can create a thin, protective layer on the surface of your skin. Think of it as a breathable shield that helps to lock in moisture and protect your skin from environmental stressors like pollution and harsh weather. This film can also give your skin a smoother appearance, making it a popular ingredient in various skincare products.
One of the standout benefits of Yeast Polysaccharides is their ability to condition the skin. This involves improving the overall feel and appearance of your skin. When used in cosmetic formulations, these polysaccharides can help to soften and smooth the skin, making it feel more supple and hydrated. This is particularly beneficial for those with dry or rough skin, as it can help to restore a more youthful and healthy appearance.
Yeast Polysaccharides also have skin-protecting properties. This means they can help to shield your skin from potential irritants and harmful substances. By forming a protective barrier, they can reduce the risk of skin damage caused by external factors. This makes them a valuable addition to products aimed at sensitive or compromised skin, providing an extra layer of defense.
In addition to their benefits for the skin, Yeast Polysaccharides play a crucial role in the formulation of cosmetic products by controlling viscosity. This means they help to manage the thickness and texture of creams, lotions, and serums. By ensuring the right consistency, they make products easier to apply and spread evenly on the skin, enhancing the overall user experience.
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).
Yeast polysaccharides are generally considered safe for topical application in cosmetic products. However, as with any ingredient, there are potential side effects to be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of yeast polysaccharides 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.
Adverse reactions to yeast polysaccharides are relatively uncommon, but it is always prudent to conduct a patch test before widespread usage to ensure there is no sensitivity or allergic reaction.
In terms of comedogenicity, yeast polysaccharides have a rating of 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating means that yeast polysaccharides are unlikely to clog pores and are generally suitable for people prone to acne, blemishes, or breakouts.
