pigmentationA very worrying concern particularly in this region, pigmentation is a problem that once acquired, is extremely difficult to get rid of. As health investigates.

Types

According to Dr. Muhsen Kalaji, a Dubai based dermatologist, pigmentation or hyperpigmentation is the darkening of an area of skin caused by increased melanin. “Hyperpigmentation can be diffuse or focal, deep or superficial, inherited or acquired,” he tells. “Melasma is the most common one, which is patchy hyperpigmentation–  often found in pregnant women-and PIH (Post Inflammatory Hyperpigmentation) which is common in Arab and Asian skin types.” These are dark and discolored spots that appear on the skin following acne that has healed.


The Areas

Most people get pigmentation on their cheeks, the bridge of their nose, forehead, chin, and above their upper lip, explains Dr. Kalaji. “It also can appear on other parts of the body that get lots of sun, such as the back of the hands, forearms and neck,” he notes, while thin skin areas like eyelids and neck, are the hardest to treat.

Reasons

Many forms of hyperpigmentation are caused by an excess production of melanin, explains Dr. Kalaji. “Melanin is produced by melanocytes (pigmented cells) at the lower layer of the epidermis,” he says and is both hereditary and
acquired especially because of excess sun exposure.

Treatment

Topical agents are still the safest and effective treatment for pigmentation, suggests Dr. Kalaji. “Good products like
hydroquinone and tretinoin can lighten the spots, also procedures such as chemical peels are very helpful in many cases,” he elaborates, while some machines like lasers and radio frequency can be applied carefully in resistant cases and specific areas
