Is Post-inflammatory Hyperpigmentation Permanent?

Post-inflammatory hyperpigmentation -

Post-inflammatory hyperpigmentation or PIH is caused as a direct result of an injury or inflammation to the skin. It can be triggered by conditions such as acne or something as simple as waxing.

a) What are the symptoms of post-inflammatory hyperpigmentation?

Post-inflammatory hyperpigmentation appears as dark patches or spots on the skin. The condition may appear after suffering an inflammatory skin condition such as acne. It’s more prevalent in deeper skinned individuals due to larger melanosomes which create a greater quantity of melanin.

Post-Inflammatory hyperpigmentation or PIH as it’s abbreviated is also known as acquired melanosis and is usually temporary. Patches can fade or become lighter over time. PIH can also be persistent and remain long after a wound has healed. PIH can further darken through skin aggravation, certain medications and prolonged sun exposure without protection.

The good news is, PIH is relatively superficial. Hyperpigmentation acquired at birth or last several years can be difficult to treat. Such blemishes usually extend deep within the skin. They will in many cases require invasive treatments such as laser resurfacing. PIH on the hand can successfully be treated with low to moderate skin regenerative treatments such as chemicals peels and micro-needling.

b) What can I do to prevent post-inflammatory hyperpigmentation?

Inflammation is the first stage of the natural healing process. Unless we are permanently free of skin inflammation PIH will exist. It is our bodies way of healing itself. So whilst we can’t prevent PIH there are steps we can take to lessen its occurrence.

  • Identify skin type – By using the correct skincare products our skin we will be less prone to irritation with less chance of PIH caused by stress.
  • Avoid picking – Picking at spots or wounds whilst they are still healing will, sure enough, leave a mark.
  • Use sun protection – Given the fact a large portion of a deeper skin aesthetic complaints will be pigmentary in nature, many deeper skins do not use sun protection. PIH will worsen unprotected in the sun.
  • Be proactive – Always assume PIH will not fade on its own. Once we’ve suffered an injury or a few spots have healed, we should embark on a skincare routine that encompasses exfoliation and lightening. Regenerative skin treatments expedite cell turnover and skin renewal. The quicker PIH is treated, the greater chance of positive results.

c) What skin treatments are good for post-inflammatory hyperpigmentation?

Two aesthetic treatments work particularly well for PIH. Chemical peels and micro-needling. Both are a form of control wound healing. We damage or break down the old blemished skin and encourage new brighter skin to the surface.

Chemical peels, although as the name suggests are not chemicals. They are natural substances derived from milk, sugar cane, willow bark and citrus fruit amongst others. Chemical peels work by breaking down the keratin protein in dead skin cells destroying them and subsequently they flake away. The effect is fairly subtle and so we describe superficial to medium depth chemical peels as progressive. The greatest results will be achieved over 3-6 treatments.

The complete removal of the epidermis or outer layer of skin is known as an ablative treatment. This method is risky for deep skinned individuals. If we think back to what causes PIH, it’s the injury and healing of wounds. An aggressive treatment could trigger irreversible burns and hyperpigmentation.

Darker skin with PIH benefits a gradual controlled wound healing that encourages newer, fresher and brighter skin to appear. If the wound is too great or too fast, there is a significant risk of worsening the problem. Mandelic acid is one of the best agents to use on post-inflammatory hyperpigmentation.

Micro-needling is a skin regenerative treatment which triggers healing mechanisms of the skin. The healing process stimulates new collagen, elastin and water-retaining hyaluronic acid deep within the skin. skin regeneration produces a finer, smoother complexion and as a result, post-inflammatory hyperpigmentation and scarring are significantly improved.

As with chemical peels, micro-needling is progressive. Greater results are achieved over time. Micro-needling is especially good for PIH when it is accompanied by acne scars such as box scars.

Microdermabrasion is a mechanical exfoliation procedure for superficial skin resurfacing which utilises a refined abrasive element, such as a diamond-tipped pad aerosolised crystals, to gently remove the outermost skin layers. This controlled wounding process stimulates cell renewal with the regeneration of a healthier and even skin tone.
