Post-inflammatory hyperpigmentation (PIH) is a common skin condition characterized by dark spots or patches that appear after an inflammatory event. These spots occur because of the skin's natural healing process after it has been injured or irritated. Although PIH is not harmful, it can cause significant cosmetic concerns for those affected. This short read delves into effective tips for hyperpigmentation skincare.

What Causes Post-Inflammatory Hyperpigmentation?
PIH typically occurs after any form of skin trauma that triggers inflammation. Common causes include:
Acne: Acne lesions, especially those that are picked at or squeezed, can lead to PIH. The inflammatory process that occurs when the skin heals from an acne breakout often results in the production of excess melanin, the pigment responsible for skin colour.
Sunburn: Prolonged sun exposure causes the skin to react by producing more melanin as a defense against ultraviolet radiation. After the skin heals from a sunburn, PIH can develop, leaving dark spots or patches.
Infections And Skin Irritations: Any infection, such as fungal or bacterial infections, can lead to inflammation. Similarly, conditions like eczema, psoriasis, or contact dermatitis can also result in PIH.
Chemical Or Physical Injuries: Cuts, burns, or aggressive cosmetic procedures like chemical peels or laser treatments can all lead to inflammatory reactions that result in PIH.
Medications And Treatments: Certain medications, like oral contraceptives or hormone replacement therapy, can increase the skin's sensitivity, potentially contributing to PIH when combined with skin inflammation.

Symptoms Of Post-Inflammatory Hyperpigmentation
The primary symptom of PIH is the appearance of darkened skin in areas where the skin has previously been inflamed. These dark spots can vary in size, shape, and colour, but they are usually darker than the surrounding skin and may appear brown, red, or purple. The spots typically develop a few days to weeks after the inflammatory event and may persist for several months. PIH tends to be more prominent in individuals with darker skin tones, as the increased melanin production leads to more noticeable discoloration. The spots are often flat but may vary in texture depending on the severity of the original inflammation.
Does PIH Fade On Its Own?
In most cases, PIH fades with time, though it may take several months or longer to completely disappear. Sunscreen is crucial in preventing further darkening of the spots, as UV exposure can exacerbate hyperpigmentation. Understanding the causes and symptoms of post-inflammatory hyperpigmentation is important for its prevention. While PIH can be frustrating, a proper skincare regimen and sun protection can help minimize its appearance over time.
