Soluble elastin is a water-soluble derivative of elastin, a protein that is naturally found in the connective tissues of animals, particularly in the skin, lungs, and arteries. In the context of cosmetics, soluble elastin is often referred to by other names such as hydrolyzed elastin or elastin hydrolysate. This ingredient is prized for its skin conditioning properties, making it a popular addition to various skincare products.
The use of elastin in cosmetics has a rich history. Initially, elastin was extracted from animal tissues and used in its insoluble form. However, due to its limited solubility and bioavailability, scientists developed methods to hydrolyze elastin, breaking it down into smaller, water-soluble peptides. This hydrolyzed form, known as soluble elastin, is more easily absorbed by the skin, enhancing its effectiveness in cosmetic formulations.
The process of making soluble elastin involves the hydrolysis of elastin fibers, typically sourced from bovine or porcine tissues. This hydrolysis process breaks down the large, insoluble elastin molecules into smaller peptides that are soluble in water. These peptides retain the beneficial properties of the original elastin, such as promoting skin elasticity and hydration, but are more readily incorporated into cosmetic products.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Soluble Elastin:
Soluble Elastin is primarily known for its skin conditioning properties. This means it helps to maintain the skin in good condition, making it feel smoother and softer. When applied in cosmetic formulations, Soluble Elastin can enhance the skin’s texture, giving it a more supple and youthful appearance. Essentially, it works to improve the overall feel and look of your skin by ensuring it stays hydrated and elastic.
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).
Soluble elastin is generally considered safe for topical application in cosmetic products. However, as with any 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 soluble elastin 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 soluble elastin are relatively uncommon, but it is always prudent to conduct a patch test before widespread usage to ensure personal tolerance.
Soluble elastin has a comedogenic rating of 1, which means it is unlikely to clog pores and is generally suitable for individuals prone to acne, blemishes, or breakouts.
