How to Identify and Treat Post-Inflammatory Hyperpigmentation

Post-inflammatory hyperpigmentation is a common skin condition that can be categorized with dark spots or patches on the skin. While these are harmless and may affect anyone, regardless of their skin type or ethnicity, the long-term effects of hyperpigmentation may potentially impact self-esteem and cause emotional distress to an individual. With its widespread prevalence in mind, it is integral to understand what constitutes post-inflammatory hyperpigmentation in detail to equip yourself with the knowledge to identify and treat the condition to manage these stubborn marks in the future.

Keynotes:

• Post-inflammatory hyperpigmentation refers to non-textured, flat, discolored patches that manifest after trauma to the skin.
• Inflammatory skin conditions like acne, cuts, eczema or sunburn as well as mechanical trauma such as picking and scratching, may cause PIH.
• Certain effective methods to combat the condition are topical treatments, chemical peels, light and laser therapy.
• Inculcate gentle skincare practices while daily usage of sunscreen and early intervention can help minimize the risk of further aggravating PIH.

Post-inflammatory hyperpigmentation can be seen as the body’s response to an injury or inflammation of the skin with an overproduction or uneven distribution of melanin. The trauma or irritation induced by acne, cuts, eczema or sunburn is met with a flush of pigment (melanin) that supports the deeper layers of the skin from further damage and boosts the wound-healing process.

That said, while the irregular disposition of the pigment may seem similar to that of a scar, inflammatory hyperpigmentation is vastly different from it. A distinct characteristic of PIH is that it typically does not alter the texture of the skin but shows up as flat, discolored patches that are deeper than your natural skin tone. Moreover, unlike scars, the severity and duration of these dark patches are based on a variety of factors, depending on individuals, genetics, depth of inflammation, as well as skin tone.

Understanding the distinction between the two is integral to pinpointing the post-inflammatory hyperpigmentation treatment that is best suited for your needs to mitigate any potential impacts and ensure healthy, even-toned skin.

As we distinguished PIH from scars in the above argument, understanding its characteristics, such as discoloration, can help you plan the best treatment for post-inflammatory hyperpigmentation ahead. Here are some properties to look out for:

1. The Appearance of Dark Spots

   The inflammation induced by aggravators leaves your skin patchy and darker than your usual skin tone. These spots are flat and typically uniform in texture. However, they can manifest in an array of colors from tan to dark brown, red, purple and even bluish-grey in some cases.

2. Location of Dark Spots

   One of the key telltale signs of post-inflammatory hyperpigmentation is the site or location of previous trauma wherein your skin barrier was damaged or inflamed. These could be as simple as the location of your last healed pimple or a faded rash that you contracted a while back. These characteristics can help you distinguish between two types of hyperpigmentation:

   • Epidermal hyperpigmentation: This is categorized by an excess deposit of melanin (light brown to black discoloration) concentrated in the upper layers of the skin, also known as the epidermis. This is more responsive to post-inflammatory hyperpigmentation treatment and may fade over time.
   • Dermal hyperpigmentation: On the other hand, this involves deeper layers of the skin known as the dermis. This is why the dermal type of PIH tends to be more stubborn and may require prolonged treatment. The pigment appears on the skin as bluish-grey to brown patches, depending on the inflammation.

3. Timeline of Development

   However, compared to the other two, this characteristic of PIH can vary based on the condition. Typically, hyperpigmentation appears shortly after the onset of the inflammation and may take weeks at a time to manifest. Whereas, when it comes to fading, epidermal hyperpigmentation may improve if the disorder-causing agent is addressed efficiently.

Before we understand the treatment for PIH, let’s sort through some of the common causes and triggers:

1. Inflammatory Skin Conditions

   At most times, skin inflammation is the root cause of anti-inflammatory hyperpigmentation. These conditions form lesions and disrupt the normal skin process, prompting the release of melanocytes, stimulating cytokines. Some of the most common triggers include acne, eczema, psoriasis, and so on. These skin conditions leave behind itchy, red patches of skin that later turn pigmented after the active inflammation subsides.

2. Excessive Sun Exposure

   One of the most famous culprits that exasperates hyperpigmentation is long periods of sun exposure. UV radiation from the sun stimulates melanin production in the body. This hinders the existing hyperpigmentation's resolution and aggravates it further.

3. Picking or Scratching the Skin

   Just as skin conditions trigger hyperpigmentation, mechanical trauma from picking, scratching, or irritating the skin in any way can also often increase the risk of manifesting PIH. Hence, it is recommended that one resist the urge to pick or scratch at a scab or a burn and leave it undisturbed to support the healing process.

Now, here's some good news: inflammatory hyperpigmentation does fade over time, albeit with effective treatment and care. Patience is always a virtue to have during such times. Here are a few post-inflammatory hyperpigmentation treatment options available to address the concerns:

1. Use Brightening Ingredients

   Topical treatments, such as serums, are often the most commonly employed treatments for fading hyperpigmentation among the masses. Such agents focus on reducing the inhibitory effects of melanin and thereby treating hyperpigmentation in the long term. Certain over-the-counter ingredients that you may come by for PIH are retinoids, licorice extracts, kojic acid, hydroquinone, and azelaic acid.

2. Exfoliate to Promote Cell Turnover

   While topical solutions are important, understanding the nature of your skin and gently exfoliating it can be detrimental in discarding dead skin cells. This step turns out to be integral in your skincare routine as it promotes the growth of new skin cells. Certain chemical exfoliants, for instance, alpha hydroxy acids (AHA) or beta hydroxy acids (BHA) such as glycolic acid, lactic acid or salicylic acid are effectively employed in this process.

3. Hydrate and Protect the Skin Barrier

   Let’s be honest, a lot of PIH treatments can turn out to be a little invasive to the skin. Hence, gentle care and hydration are needed to ensure a resilient skill barrier or fundamental for an effective treatment. A few ways to nurture your skin barrier are to use a gentle sulfate-free cleanser that focuses on balancing your skin's pH without stripping its natural oils. Then follow up with a rich day cream with ingredients such as hyaluronic acid and glycerin to support your skin health and minimize any potential irritation that your skin may incur due to the chemical peels.

4. Consider Professional Treatments

   If continued efforts over your skincare routine do not yield satisfactory results, then try consulting with a board-certified dermatologist to discuss potential professional treatments. They might often recommend procedures such as chemical peels, laser treatments that focus on set pigmented areas, or blue light photodynamic therapy which may further target the underlying pigmentation pathways for an effective result. That said, a professional assessment is vital to determine the length of your condition and its suitable treatment.

Untimely acne cannot be prevented; however, these are some strategies that one can implement to minimize the risk of the scars:

• Opt for Gentle Skincare

  Your skincare routine should be centered around non-irritating products that focus on care with the repair. While exfoliating is integral, one may always look for gentle toners or serums with soothing ingredients like green tea, ceramides or peptides to support strong actives like salicylic acid or retinoids.

• Avoid Picking at Your Skin

  We know this is easier said than done. Picking, scratching or poking and prodding at the scab or dry skin comes naturally. However, if you want to give your skin the rest and the chance to heal, it should be treated and left alone.

• Use Sunscreen Daily

  A high-quality broad-spectrum SPF 50+ is the holy grail for healthier skin. The product not only is crucial to protect the skin from UVA and UVB rays but also lowers the likelihood of hyperpigmentation flare-ups due to the sun.

• Prioritize Early Intervention

  If you have characteristically sensitive skin and are prone to bursts of acne, eczema or any other inflammatory skin conditions, then timely action will help you reduce the effects leading to PIH. Early intervention and consultation with your board-certified dermatologist will help you plan a personalized roadmap for post-inflammatory hyperpigmentation treatment.

1. How do you know if you have post-inflammatory hyperpigmentation?

   If you notice flat, discolored spots or blemishes left behind after inflammatory skin conditions like acne, sun exposure or eczema, then you likely have inflammatory hyperpigmentation. Unlike scabs or scars, these do not change the texture of your skin and only affect the pigment of the impacted area.

2. How do you treat post-inflammatory hyperpigmentation?

   There are several post-inflammatory hyperpigmentation treatment options one can employ to reduce the degree of pigmentation and prevent any further damage to the skin. These include over-the-counter solutions like topical actives or dermatologist-approved professional treatments like chemical peels, laser therapy, or light therapy.

3. How long does it take for post-inflammatory hyperpigmentation to fade?

   The duration at which your post-inflammatory hyperpigmentation begins to fade varies greatly based on the type. Epidermal hyperpigmentation may start to fade after months once the inflammation subsides. While dermal hyperpigmentation needs consistent use of professional targeted treatments to expedite the process.
