Acne is a common disorder that affects many people. It often starts in puberty and can continue well into adulthood. Symptoms of acne include tender, red spots and pustules that later turn into pimples.
Over production of sebum and oil from the sebaceous glands causes narrowing of the pore, which in turn leads to a blockage. Sebum builds up and causes “whiteheads” or comedones. These can become infected by bacteria, which usually live harmlessly on the skin known as Propionebacterium acnes (P-Acnes), and this is what causes the red, sore infected spots.
