Post inflammatory hyperpigmentation is a condition that manifests as dark lesions on the skin that appear after a disease, infection or injury has healed. These lesions range on color from slightly darker than the surrounding skin to almost black, and they tend to be more common in non-Caucasians due to their darker skin tone. The lesions are often mistaken for scars, but they aren’t permanent, although they can take months or even years to fully heal. Like most hyperpigmentation conditions, they are rarely a serious problem.
What are the causes?
Post inflammatory hyperpigmentation develops when damage to the epidermal layer of the skin causes the release and oxidation of arachidonic acid to products such as prostaglandins and leukotrienes. This in turn affects the activity of immune cells and melanocytes. Melanocytes produce melanin, the pigment that gives the skin its natural color. An excess of melanin in a part of the body creates darker spots in the skin.
Practically any injury or infection that affects the skin can result in post inflammatory hyperpigmentation. Some of the most common causes include acne, burns and allergic reactions. Many believe that the lesions are often caused by acne medication, although this is rarely the case. More often than not it is the acne and not the medication that results in any skin discoloration.
What are the treatment options
Post inflammatory hyperpigmentation treatment is usually similar to other hyperpigmentation treatments. Since other forms of hyperpigmentation are often caused by sun damage, many doctors recommend the use of sunscreen to prevent further darkening of any lesions that may form. More specific treatment options include the use of skin lightening creams containing hydroquinone or Retin-A as well as corticosteroid creams that may be prescribed by a doctor. More extreme treatments such as chemical peels, laser surgery and intense pulsed light therapy can be effective, but they also tend to be more expensive and may aggravate other pigmentation problems.
