Acne

Introduction

Acne is a dermatological condition that causes pimples and includes whiteheads, blackheads, red, inflamed patches as well as pus filled vesicles on the skin. Acne occurs when tiny holes also called as pores on the surface of the skin become blocked. Each pore on the skin as connected to a hair follicle and an oil secreting gland. This gland releases oil which causes removal of dead skin cells. When a gland produces excess oil, then the pore is blocked. Dead cells, bacteria and dirt accumulate on it. This block is called as plug or come done. Depending on the color of surface of the plug, it can be whitehead or blackhead. When the plug erupts, redness and swelling appears. Pus may form in this plug. When the plug is deep inside the skin, it forms hard, painful cysts and this is called cystic acne.

Causes and incidence:

Acne is most common in teenagers because the hormonal changes cause skin to release more oil. They can occur rarely in babies also. Sometimes, acne tends to run in families.
