S-Lactoylglutathione, also known by its chemical name Glycine, N-[S-(2-hydroxy-1-oxopropyl)-N-L-gamma-glutamyl]-L-cysteinyl-, is a compound that has found its niche in the world of cosmetics primarily for its skin conditioning properties. This ingredient is a derivative of glutathione, a powerful antioxidant naturally found in the body. Glutathione itself has been widely studied for its role in reducing oxidative stress and promoting overall skin health.
The history of S-Lactoylglutathione in cosmetic products is relatively recent. It emerged as a promising ingredient due to its enhanced stability and efficacy compared to regular glutathione. Researchers discovered that by modifying glutathione to create S-Lactoylglutathione, they could improve its ability to penetrate the skin and deliver more consistent results. This innovation has led to its inclusion in various skincare formulations aimed at improving skin texture and appearance.
The production of S-Lactoylglutathione involves a biochemical process where glutathione is combined with lactic acid. This reaction results in the formation of a more stable compound that retains the beneficial properties of glutathione while being more suitable for topical application. The synthesis process ensures that the ingredient is both effective and safe for use in cosmetic products, making it a valuable addition to the skincare industry.
In this section, we will delve into the officially recognized cosmetic benefits and uses of S-Lactoylglutathione:
S-Lactoylglutathione is primarily known for its skin conditioning properties. This means it helps to maintain the skin in good condition, making it feel smoother, softer, and more hydrated. When included in cosmetic formulations, it can enhance the overall texture and appearance of the skin, giving it a healthier and more youthful look. Essentially, it acts as a moisturizer and a skin-soothing agent, making it a valuable ingredient in skincare products aimed at improving skin feel and appearance.
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).
S-Lactoylglutathione 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 S-Lactoylglutathione during pregnancy and breastfeeding are lacking. Therefore, it is advisable to consult a healthcare professional for further advice before using products containing this ingredient.
Side effects and adverse reactions from S-Lactoylglutathione are generally uncommon. However, it is recommended to perform a patch test before widespread usage to ensure there are no adverse reactions.
In terms of comedogenicity, S-Lactoylglutathione has 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 it is unlikely to clog pores and is generally suitable for people prone to acne, blemishes, or breakouts.
