Top 3 Black or Brown Butt Bump Causes

  1. 1.Blackhead

    Blackheads are caused by hair follicles becoming clogged with oil & dead skin cells. When the clogged pore is open to the air, the air turns the outermost layer black through oxidation.

    Though large blackheads can be removed by a dermatologist, most cases can be treated with proper hygiene and over-the-counter medications/treatments. Look for products containing benzoyl peroxide or salicylic acid.

    Moles are growths on the skin. They happen when pigment cells in the skin, called melanocytes, grow in clusters.

  3. 3.Dermatofibroma

    Dermatofibroma (superficial benign fibrous histiocytoma) is a common cutaneous nodule of unknown etiology that occurs more often in women. Dermatofibroma frequently develops on the extremities (mostly the lower legs) and is usually asymptomatic, although pruritus and tenderness can be present

    You do not need treatment for this condition because it is completely benign; however, if the lesion changes at all, a doctor should be consulted. If you would like it removed, a doctor can cut, freeze, or burn it off.
