Hyperpigmentation

Pigmentation means  the colouration of the skin. Our body contains a pigment known as  melanin which determines the colour of our skin, hair and eyes.

Many patients may begin to notice the presence of tan to brown to gray patches on their skin, which are often worsened with sun exposure. This condition is called hyperpigmentation and affects both men and women. It can occur in all skin colors, but is typically more common in patients with darker skin tones.

Hyperpigmentation occurs when the pigment-producing cells of the skin, called melanocytes, begin to produce too much pigment. Hyperpigmentation can appear anywhere on the skin. Common causes include inflammation and/or trauma on the skin, medications, genetics and hormonal changes. Pigmentation that follows trauma to the skin, such as a cut, burn, abrasion or surgical incision, or inflammation in the skin, such as after a rash, acne or severe skin dryness, is known as post-inflammatory hyperpigmentation. The effects can also become more obvious as we age and if left untreated and unprotected can worsen.

As sun exposure worsens hyperpigmentation it is important to protect the skin with sunscreen SPF 50+ on a daily basis. Treatment often begins with a skin care regimen composed of a daily sunscreen, moisturizers, and skin care brighteners. Some of the more common skin brighteners include hydroquinone, vitamin C, azelaic acid, tretinoin and kojic acid.
