What is hyperpigmentation?

Hyperpigmentation (dark spots) is a common skin problem where patches of skin become darker than the surrounding skin, due to an excess deposit of melanin. Melanin is the substance that gives our skin its color. Hyperpigmentation affects people of all skin colors.

Dark spots include brown spots, birthmarks, age spots, liver spots, freckles, sunspots, and melasma. Melasma is hyperpigmentation due to hormonal changes. Post-inflammatory hyperpigmentation results from an inflammatory skin condition.

Hyperpigmentation can affect any area, but is commonly found on the face, ears, back of the hands, arms, neck, chest, shoulders and back. Hyperpigmentation is not dangerous but is cosmetically unappealing.

What causes hyperpigmentation?

Hyperpigmentation can result from sun damage, acne scarring, heredity, some prescription medications, and hormonal imbalances.

Melasma

Melasma is a common problem that affects women. It is caused by hormone changes. Intense UV radiation exposure and a genetic predisposition play a role in the development of melasma. In pregnancy it is called the “mask of pregnancy”. Melasma can also be caused by birth control pills and hormone replacement therapy.

Melasma appears as brownish-gray patches on the face, bridge of the nose, forehead, chin and upper lip. Sun exposure can trigger the return of melasma after it has faded. Melasma is difficult to treat and may require maintenance therapy after it clears. Common treatments include topical treatments include Hydroquinone, Retin A, and Azelaic acid. However, Dr. Farhang is an expert who trained in Miami where there are many cases of melasma. Dr. Farhang works with a local pharmacy to help create/compound a topical product with several ingredients. In addition, she is one of few in the country who knows how to prescribe a new cutting-edge oral treatment with much success.

Sun spots (Solar Lentigines)

Sun spots are flat pigmented spots on sun exposed skin. Sun spots are caused by sun damage that occurred in the past. 90% of light-skinned people over the age of 60 have age spots. Age spots typically appear on the face, hands, forearms, chest, back and shins.

Common treatments include:

  • Chemical peels
  • Photofacial
  • Laser skin resurfacing
  • Topical creamsย 

Combination treatment has been found to be the best approach, in addition to the daily use of a sunscreen.

Post-inflammatory hyperpigmentation (PIH)

PIH is hyperpigmentation caused by an inflammatory skin condition like acne; skin infections from bacteria, viruses, and fungus; skin eruptions due to certain medications; eczema and psoriasis or another skin inflammation.

Acne breakouts often result in PIH. PIH is the discoloration left after acne or other inflammation heals. PIH can be pink, red, purple, brown or black flat discolored areas. Acne scars may also be discolored. Overexposure to the sun, and drugs that cause hypersensitivity to the sun, such as some antibiotics, can cause PIH.

PIH discolorations may fade with time but take a long time to fade. It can take several months or longer superficial spots to fade, and longer to treat deeper discolorations that may not fade on their own. People with medium to dark complexions are more prone to PIH especially in areas with intense sun exposure such as Arizona

To control your risk for PIH from acne, the first step is to get your acne under control. If you already have PIH there are effective treatments.

Common treatments may include:

  • Alpha hydroxy acids like glycolic acid speed exfoliation and can improve PIH.
  • Hydroquinone
  • Retin A
  • Azelaic acid
  • Chemical peels
  • Microdermabrasion
  • Laser skin resurfacing
