Every talk about acne includes terms such as whiteheads and black heads. What are they and why are they called so? Let us find out. Acne develops on the hair follicles that have sebaceous glands attached to them. These glands produce an oil called sebum. Because of certain reasons the sebum changes in quality and quantity giving rise to scales on the hair follicle. This blocks the skin pore causing acne. This blockage is the beginning of acne. The first stage of this blockage shows as blackheads and whiteheads. These are also called as comedones. A comedone is a sebaceous follicle that is plugged and filled with sebum, dead cells etc. An open comedone is called a blackhead because of its blackish appearance. A blocked comedone is referred as white head, which is a small bump in the skin with skin like color. A whitehead has closed mouth and the blackhead has an open mouth. What to do if you have blackheads or whiteheads- do not squeeze them yourself. That may leave permanent scars and also infection. Best is to approach a dermatologist who will pick them open if required under sterile conditions. Please note that acne scars can permanently disfigure you. As far as basic care is concerned, wash your face gently with slightly warm water and mild soap to remove excess sebum and dead skin. Do not be harsh on the skin. Please note that acne takes time to clear. Apply any topical cream that may be prescribed by your dermatologist. Acne treatment requires patience.
