Streptococcus Thermophilus/Milk Ferment Lysate is a fascinating ingredient in the world of cosmetics, derived from the fermentation of milk by the microorganism Streptococcus Thermophilus. This ingredient is also known by other names, such as Milk Ferment Lysate Filtrate or simply Milk Ferment Lysate. Chemically, it is a lysate, which means it is a product that results from the breakdown of cells, in this case, the cells of Streptococcus Thermophilus after they have fermented milk.
The history of Streptococcus Thermophilus/Milk Ferment Lysate in cosmetics is relatively recent but rooted in the long-standing tradition of using fermented products for skin health. Fermentation has been used for centuries in various cultures for its beneficial effects on the skin, primarily due to the presence of probiotics and other bioactive compounds. The cosmetic industry has harnessed this ancient wisdom and applied modern scientific techniques to create this unique ingredient.
The process of making Streptococcus Thermophilus/Milk Ferment Lysate involves fermenting milk with the Streptococcus Thermophilus bacteria. During fermentation, the bacteria break down the milk’s components, producing a variety of beneficial substances, including peptides, amino acids, and enzymes. After fermentation, the mixture is lysed, meaning the bacterial cells are broken down to release their contents. This lysate is then filtered and purified to create the final ingredient used in cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Streptococcus Thermophilus/Milk Ferment Lysate:
Streptococcus Thermophilus/Milk Ferment Lysate is primarily known for its skin conditioning properties. This means that it helps to maintain the skin in good condition. When applied in cosmetic formulations, it can enhance the appearance and feel of the skin, making it softer, smoother, and more supple. This ingredient works by providing essential nutrients and promoting a balanced skin environment, which can be particularly beneficial for those with dry or sensitive skin.
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).
Streptococcus Thermophilus/Milk Ferment Lysate 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 Streptococcus Thermophilus/Milk Ferment Lysate 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 this ingredient are generally uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure there are no adverse reactions.
On a comedogenicity scale of 0 to 5, Streptococcus Thermophilus/Milk Ferment Lysate is rated as 0, meaning it is non-comedogenic. This makes it suitable for individuals prone to acne, blemishes, or breakouts, as it is unlikely to clog pores or exacerbate these conditions.
