Abstract

The beneficial effects of probiotics on human health are widely recognized. Recent findings demonstrate the excellent opportunity also for topical applications, highlighted by the growing demand from worldwide end-users.
This work aims at presenting the evidence of effectiveness towards a new cosmetic ingredient, based on Lactobacillus rhamnosus LRH020. Specially designed for promoting the skin ecosystem’s well-being, the result is the novel ability to strengthen the skin barrier and its natural defenses by rebalancing skin microbiota. In addition, the study will describe a series of in-vitro and in-vivo tests supporting the scientific efficacy background of the ingredient.

INTRODUCTION
The cosmetic market is experiencing an incredible revolution regarding microorganisms, considering both a target and potential topical applications. More and more products containing pre-, pro- and post-biotics have been launched with claims referring to the rebalance of skin’s microbiota. Along with the products growing quantity, confusion about the ingredients used for the treatment of the microbiota and their classification also grows. The safest way to insert microorganisms as real ingredients is to make them inactivated and more stable within a cosmetic formula.
Probiotic-derived is currently classified as ‘postbiotic’ and maintains structural integrity by preserving cells membrane. This process allows to have an interaction comparable to probiotics and to guarantees some benefits associated with live microorganisms such as strengthening skin barrier and its natural defenses (1).
