Our blackhead & whitehead-banishing and pore-refining formulas feature ingredients that address the root of blackheads & whiteheads and clear out pores—all without irritating skin. If you want to target blackheads & whiteheads make sure you follow the correct daily routine. Blackheads & whiteheads are caused by an overproduction of sebum that accumulates in your pores. Dead skin cells that clog the opening of the pore also contribute to this. The pore then gets clogged, which may result in a blackhead or whitehead.
