Pimples or acne are a combined result of several bodily changes that occur around puberty. During puberty, secretion of the hormone called androgen increases in both boys and girls. Androgen can also increase because of hormonal changes related to pregnancy or starting or stopping birth control pills. It normally happens around teenage and makes the sebaceous (oil) glands become more active. Sebaceous glands are on the hair follicles under the skin. In humans sebaceous glands exist throughout the body except the palms and soles. There is abundance of sebaceous glands on the face. These glands produce sebum, an oily substance which carries dead skin cells through the follicles to the surface of the skin. In normal circumstances sebum is produced in small amount and is discharged through a narrow pore on the skin. But if the quantity of sebum produced is high, it is not discharged as easily. It accumulates under the skin and the part near the pore turns black because of oxidation with the air. This part is generally referred to as blackhead. Blackheads spoil the looks, and it doesn't stop there. After a while bacteria develop in the sebum and that causes inflammation of the skin, worsening the pimple. After the sebum is removed, there remains a permanent dent on that part of the skin.
