Most teenagers and some adults experience a skin condition called acne. It is caused by changes inside the body which occur naturally as a boy or girl reaches puberty, or matures. At that time the body produces more of chemicals called hormones. Some of those hormones speed up the skin's production of oil. ---- As the oil gland under a blocked pore makes more oil, the pore swells up to form a pimple.
