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.
Oil-free soaps won't clog your pores or cause blackheads, whiteheads, and acne. Choose products that are labelled 'oil free', 'nonacnegenic', or 'noncomedogenic'. Apply the soap and wash with your fingertips.Flannels, mesh sponges or other products may be too abrasive and can irritate the skin and cause breakouts.cne occurs when pores are blocked by oils, skin cells and normal bacteria, causing inflammation. Some foods may trigger a hormonal reaction that leads to an overgrowth of skin cells or too much oil production. So, if certain foods seem to cause you to break out in spots, try to avoid them.
