Lactobacillus is a genus of lactic-acid-producing bacteria used in cosmetics, often as an inactivated culture or ferment. In skincare and sunscreen formulas it is associated with conditioning and soothing roles and is frequently described as supporting the skin's surface balance. Because it derives from microbial fermentation, it appears in products positioned around skin-friendly or probiotic-inspired care.

In skincare and sunscreen formulas it is used mainly as a skin-conditioning ingredient, contributing fermentation by-products such as peptides, amino acids, and other soy-derived compounds. It is typically added to give the skin a conditioned, soft feel.
