Acne is the common cause of spots. Most people with acne are aged between 12 and 25, but some older and younger people are affected. Boys are more commonly affected than girls. Acne usually affects the face but may also affect the back, neck, and chest. The severity can range from mild to severe. About 9 in 10 teenagers develop some degree of acne. Often it is mild. However, it is estimated that about 3 in 10 teenagers have acne bad enough to need treatment to prevent scarring. Untreated acne usually lasts about 4-5 years before settling. However, it can last for many years in some cases.

Process of Acne

P. acnes is the bacterium responsible for inflamed acne breakouts. P. acnes are regular residents within the hair follicle. Normally, they are harmless. However, in acne prone skin the P. acnes population grows out of control. When a come do (the obstruction of pore is called a come do) blocks the pore opening, it creates an anaerobic environment, or a lack of oxygen within the follicle. This anaerobic environment, along with excess sebum within the pore, creates a favorable environment where P. acnes bacteria can thrive. As the follicle becomes filled with sebum, dead cells, and bacteria, it begins to swell. The follicle wall ruptures and spills into the dermis. White blood cells rush in to fight the bacteria. Redness and swelling occurs, and pus is created.

Types of Acne


Whiteheads and blackheads are created when the openings of hair follicles become clogged and blocked with oil secretions, dead skin cells and sometimes bacteria. When come done are open at the skin surface, they’re called blackheads because of the dark appearance. When come done are closed, they’re called whiteheads — slightly raised, skin-colored bumps.

2. Moderate and Severe Acne

Papules are small raised bumps that signal inflammation or infection in the hair follicles. Papules may be red and tender.

Pustules (pimples) are red, tender bumps with white pus at their tips.

Nodules are large, solid, painful lumps beneath the surface of the skin. They’re formed by the build-up of secretions deep within hair follicles.

Cysts are painful, pus-filled lumps beneath the surface of the skin. These boil-like infections can cause scars.

How to take care of Acne

  1. Do not wash affected areas of skin more than twice a day. Frequent washing can irritate the skin and make symptoms worse.
  2. Wash the affected area with a mild soap or cleanser and lukewarm water. Very hot or cold water can make acne worse.
  3. Don’t try to “clean out” blackheads or squeeze spots. This can make them worse and cause permanent scarring.

Avoid using too much make-up and cosmetics. Use water-based products that are described as non-come do genic (this means the product is less likely to block the pores in your skin).
