Why does the white stuff in a pore smell?

The white substance in a pore is often a mix of sebum (oil produced by the skin), dead skin cells, and bacteria. When this mixture becomes trapped in the pore, it can lead to bacterial growth and decomposition, which produces an unpleasant odor. Additionally, the breakdown of organic material in the clogged pore can release volatile compounds that contribute to the smell. Regular cleansing can help prevent this buildup and reduce odor.
