Acne scars

What are acne scars

Acne scars form when acne spots penetrate the skin at a level that’s deep enough to reach and damage the tissues  underneath them.

Acne scars can be distinguished between:

  • Hyperpigmented scars
  • Atrophic scars
  • Hypertrophic and keloid scars

Prognosis of the disease

The development of scars and type of scars varies from person to person and are influenced by several factors like the size and depth of the scars. There are various treatments available to lessen the severity of acne scarring and to prevent future breakouts of acne.

What causes acne scars?

  • Hyperpigmented scars are caused by a concentration of pigmentation the spot during its healing process. This leaves behind a pink or brown mark once the spot has disappeared.
  • Atrophic scars caused by acne are characterised by flat and shallow indents in the skin due to a lack of collagen. In this case, not enough tissue was produced during healing to cover the entire area of the spot.
  • Hypertrophic and keloid scars are raised lumps of scar tissue. These are caused when scar tissue builds up. While hypertrophic scars tend to be the same size as acne spots, keloid scars can grow larger than the original blemish.

Can acne scars be prevented?

Resist the urge to pick or squeeze blackheads, pimples and other imperfections with your fingers or any other object. Excessive pressure on spots (especially those that are not yet fully formed) can damage the fine veins, glands, and surrounding tissues. This can make acne symptoms worse and increase the risk of scarring.

Treatments for acne scars

Acne scars or acne scars can be removed with different methods. The best one will depend on your skin type and the type of scar:

The application of a laser is not painful. It consists of aiming the laser light (emitted from a specialised device) at the scar to reduce the lesions of the first layers of the epidermis and to smooth the skin irregularities. This will eliminate the scars gradually as it causes the renewal of the surface layers of the skin.

In the case of hypertrophic and keloid scars, techniques such as surgical removal, cryotherapy and 5-fluorouracil infiltrations can be used.

What type of specialist treats acne scars?

Dermatologists specialise in diagnosis and treatment of skin conditions. They can assist in diagnosing, treating and preventing acne scars.
