What it is
Lactobacillus/Rice Ferment is created by fermenting rice with Lactobacillus bacteria, producing a material rich in fermentation by-products. It is used as a skin-conditioning agent and is popular in ferment-based and microbiome-themed formulations, particularly in Korean skincare. In sunscreens it supports the conditioning and sensory profile rather than providing UV protection.
Safety & warnings
Rice ferment ingredients are generally well tolerated and are often selected for their gentle conditioning character. People with very sensitive skin may patch test as a precaution.
Origin & sourcing
Naturally derived; produced by Lactobacillus fermentation of rice.
