What Is Lactobacillus Ferment Lysate?
Lactobacillus ferment lysate is extolled for delivering a pronounced soothing effect on skin. Studies also suggest that it plays a role in helping reinforce skin’s microbiome and thereby may reduce the severity of common skin conditions. The Personal Care Products Council classifies it as a skin-conditioning agent.\n\nLactobacillus ferment lysate is a lab-created byproduct of the probiotic Lactobacillus. As it is converted into the lysate form, the outer membrane is broken down and it is no longer a living microorganism. This allows it to function more like a postbiotic, which can be safely and effectively incorporated into cosmetic formulations to replenish skin via microbiome support.\n\nLactobacillus ferment lysate may also be used to ferment other skin care ingredients, such as plant extracts, to enhance their benefits (the fermentation process releases skin-friendly compounds and helps make them more bioavailable).\n\nIn raw material form, Lactobacillus ferment lysate appears as a cloudy, yellowish-white liquid.\n\nIt is important to note that further independent studies are needed to draw more definitive conclusions Lactobacillus ferment lysate’s benefits for skin, but at the time of this writing, what exists looks promising. Of note, emerging studies (funded by ingredient suppliers) show potential for Lactobacillus ferment lysate’s ability to prevent and treat visible signs of skin photoageing.\n\nLactobacillus ferment lysate is also marketed by a few suppliers. Because the Lactobacillus genus is non-pathogenic, the INCI names do not include the species of Lactobacillus that is being used for the fermentation product. Some of the species used are bulgaricus, helveticus, plantarum, casei, rhamnosus and acidophillus. Therefore, the different Lactobacillus ferment lysates may have very different effects on the skin.
