As its name suggests, (PIH) post-inflammatory hyperpigmentation occurs following skin injury or inflammation when skin is left darkened and discoloured after the wound has healed. This article looks at how post-inflammatory pigmentation affects skin’s appearance and what causes it. We also identify steps you can take to help reduce the appearance of dark marks on your skin.

At Rejuvenus Clinic, our clients often ask how they can revive a lifeless complexion at home and how professional treatments can enhance their results. We offer a number of solutions to address the root causes of PIH and restore a beautiful, healthy glow. Schedule a consultation to determine which treatment, or combination of treatments, is right for you.

Post Inflammatory Hyperpigmentation Rejuvenus



Post-inflammatory hyperpigmentation (or PIH for short) is a type of hyperpigmentation of the skin that is mainly triggered by the way skin regenerates after inflammation. It can affect the face and body, typically especially UV-exposed areas, and appears as flat spots of hypercoloration. These range in color from pink to red, brown or black, depending on skin tone and the depth of hypercoloration. 

Men and women are equally susceptible, and all skin types can get post-inflammatory hyperpigmentation although it is more prevalent in darker tones of skin. In fact PIH is one of the common reasons why people with darker skin tones seek the advise of a medical practitioner.

The root cause of PIH is increased melanin production. Melanin is the pigment that defines the color of a person’s skin and the increase in melanin is triggered by the way skin regenerates after inflammation or injury. The more inflammation there is, the more prominent the area of discoloration will be both in terms of size and color.

Post-inflammatory hyperpigmentation does not cause scarring and, even with no treatment, it will improve over time. Most acne-related PIH will eventually fade over time, but it can take several years or even a decade until it is fully gone. Recovery rates vary from person to person and the duration depends on the difference in skin tone between the natural skin tone and the darkened patches – the more significant the difference, the longer it will take for the tones to rebalance

Depending on the severity of your symptoms, Post-inflammatory hyperpigmentation (PIH) treatment may involve a combination of these non-invasive cosmetic treatments and medical-grade skincare. At Rejuvenus Clinic,  some of our PIH treatment options include:.


CLINICAL PEELS - Chemical peels or clinical peels involve applying a chemical solution (such as an AHA) to exfoliate skin (remove dead skin cells), stimulate the growth of new skin cells and reveal new skin. 


LASER TREATMENTS - Laser has a similar effect but tends to be more precise as the medical professional has more control over the intensity of the treatment. Laser treatments involve ‘zapping’ the affected areas with high-energy light. The mildest treatments work on the skin’s epidermis (surface layer), while more intense treatments can penetrate the deepest layers of the skin.


MEDICAL GRADE SKINCARE - If you have PIH as well as other skin conditions, our clinical specialist will recommend using medical-grade skincare products that offer a special formulation for your specific skin type with prescription-strength hydroquinone to lighten the hyperpigmentation. Hydroquinone is the first treatment option for hormonal melasma and is an active ingredient in medical-grade skincare creams, lotions, and gels. Topical retinol and retinoid treatment may also be prescribed to encourage the skin cells turnover process.

Here is a list of our Frequently Asked Questions. If you have any other questions or concerns, our experts will provide you will all the information you need.

What Is Skin Hyperpigmentation?

Hyperpigmentation is defined by an overproduction of melanin that typically makes the skin appear darker and blotchy in certain places. This skin condition usually falls into one of three categories: actinic lentigines or sun spots, post-inflammatory hyperpigmentation, and Melasma. Although hyperpigmentation is not harmful, it can make people very self-conscious and can be stubborn to treat. Post-inflammatory hyperpigmentation is caused by inflammation (after acne, eczema, or allergic reactions) and from trauma to the skin (surgery, incorrect microdermabrasion use, lasers, chemical peels, etc.). This trauma encourages the release of inflammatory cells that cause pigment cells to produce extra pigment in the skin.

How Can I Prevent Hyperpigmentation by Wearing Sunscreen?

Although sunscreen can be a part of preventing hyperpigmentation from getting worse, it takes a proper skincare regimen, and professional-grade skincare products to achieve long-term prevention. These products can slowly eliminate patches and spots of discolouration. As for Melasma, because it is a hormonal issue, sunscreen and skin products alone may not be enough to treat it. Thankfully, there are other procedures that can be done to treat Melasma and reduce the rate of frequent flare-ups.

What Causes Hyperpigmentation?

Hyperpigmentation is typically caused by sun-related UV exposure. This leads to the overproduction of melanin, which rises to the surface of the epidermis, creating a dark spot or dark patch on the skin. Hyperpigmentation can occur as a result of sunbathing, using tanning beds, and avoiding the use sunscreen. Over time, excessive sun exposure can produce sunspots, age spots, and dark spots. Melasma, however, is caused by an imbalance of hormones, and is more common in pregnant women. Melasma can also be caused by genetic makeup, passing from one generation to the next.

What Treatments Are Effective for Hyperpigmentation?

There are different ways to treat hyperpigmentation, and some are more effective than others. Professional can recommend medical treatments that are more aggressive and invasive. These may include prescription medications or chemical peels. These treatments often have long down times, and in some cases, can cause more damage to the skin. But thanks to modern technology, there have been advancements in hyperpigmentation treatments that are effective and far less damaging on your skin. At Rejuvenus, hyperpigmentation treatment uses heat and light to target the darkened spots, and remove them. Bursts of energy essentially break up the melanin in the area, which is then absorbed into the body and disappears over time.

How Can I Make Hyperpigmentation Marks Fade Faster?

If you want to treat hyperpigmentation at home, there are professional-grade skincare products that have ingredients to treat these disorders, however, product treatments can take a long time to treat and aren’t as effective in lightening the area of discolouration. While treating hyperpigmentation, it is highly recommended to wear high SPF sun protection to avoid further damage from the sun. Professional can help give you advice on an effective daily skin lightening regimen.

Are the Results Permanent?

At Rejuvenus Clinic,  we use the latest clinical methods to provide high-quality anti-aging skin and body care for our clients including a varity of treatments for hyperpigmentations. Treatments are 

permanent in that once the lesions have been removed, they will not return. However, aging, hormone changes and UV exposure can stimulate new hyperpigmentation. The treatments can treat areas that have already been affected, but cannot prevent new hyperpigmentation from occurring. We support and advise our patients to help them make informed and appropriate decisions about their skin, health, and body confidence, and we strive to provide the best skin rejuvenation services in the city.
