can blackhead expand skin pore
Pores are a natural part of the skin; blackheads are the superficial plugs that may form within them. Pore dilatation begins with faulty exfoliation of cells lining the interior gland - cells are too sticky leading to microscopic plugs. Sebaceous glands continue to produce sebum that accumulates behind the plug. Protracted pooling of skin oils serves to nourish bacteria (like P. acnes and S. epidermidis). Blackheads and enlarged pores often go hand-in-hand. Blackheads can either expand pores or simply focus attention on them.
