Acne is very common and medically classified as a skin disease. They are caused by excessive secretion of oily substance called the sebum by sebaceous glands. Although sebum is very good in maintaining skin and hair texture, excess secretion of the same gets stuck in hair follicles and leads to formation of acne lesions. Due to the oily nature of sebum and its exposure to dust and dirt causes bacterial growth and results in what is commonly known as the pimple.
