Sebium Pain gently cleanses and is the only cleansing bar that limits the formation of blemishes thanks to the Fluidactiv sebo-correcting complex, which biologically regulates sebum quality. Enriched with purifying agents, zinc sulfate and copper sulphate, Sébium Pain purifies the skin and limits sebaceous secretion. Bioderma Sebium Pain Purifying Cleansing Bar Soap perfectly cleanses and respects the skin.
