Post-Inflammatory Hyperpigmentation (PIH) is one of the most common skin concerns, especially among individuals with darker skin tones. While it’s not dangerous, it can be distressing for those affected, considering it often appears after an already frustrating skin issue like acne, eczema, psoriasis, or an injury.
Disclaimer: This is to be used only as an educational piece. Individuals should not use it to self-diagnose a skin condition or problem.
Let’s explore what PIH is, what causes it, how to treat it, and most importantly, how to prevent it.
What is Post-Inflammatory Hyperpigmentation?
Post-Inflammatory Hyperpigmentation refers to darkened patches or spots that appear on the skin after an inflammation or injury. It’s actually the skin’s natural response to trauma, a way of overcompensating in the healing process by producing excess melanin (the pigment that gives skin its color).
These spots can range from light brown to deep black, depending on the individual’s natural skin tone and the severity of the inflammation. PIH can affect the face, chest, back, arms, or any part of the body that has experienced a wound, rash, burn, or irritation.
What Causes PIH?
PIH is triggered by any skin condition that causes inflammation, including:
- Acne (especially inflamed or picked pimples)
- Eczema or psoriasis flare-ups
- Insect bites or allergic reactions
- Cuts, scrapes, or surgical wounds
- Burns (including sunburn)
- Aggressive cosmetic treatments (like chemical peels or lasers)
- Harsh skincare products that irritate the skin
- Skin bleaching products, which mostly, up to 90% always irritate the skin
When the skin tries to heal itself, melanocytes (the pigment-producing cells) are activated, leading to an overproduction of melanin in the affected area.
Who Is Most Affected?
While anyone can experience PIH, people with medium to dark skin tones are more prone to it. This is because their melanocytes are more reactive, producing more pigment in response to trauma.
Is PIH Permanent?
No, PIH is not permanent, but it can take time to fade, roughly from a few months to over a year, depending on:
- The depth of pigmentation (surface vs. deeper layers)
- Skin type
- How well the skin is cared for after the inflammation
Treatment Options for PIH
Treating Post-Inflammatory Hyperpigmentation focuses on supporting the skin’s natural healing process and gradually restoring an even skin tone. The approach usually involves personalized consistent skincare, patience, and protection to ensure that the pigmentation fades over time without being worsened by external factors.
Treatment begins with identifying and addressing the root cause of the inflammation. This can be acne, eczema, injury, or other skin conditions. This is why it is advisable to always visit your dermatologist before starting any treatment process to be sure of what you’re treating.
Once the skin is calm and healed, the next step is to encourage the fading of dark spots by improving skin renewal and helping the skin function at its healthiest.
Because PIH tends to darken more with sun exposure, protecting the skin from UV rays is critical during the healing process. Additionally, the skin must be treated gently and consistently to avoid further irritation or damage, which could delay recovery.
In many cases, with the right care and commitment, the skin naturally improves over time, and the dark spots gradually lighten.
How to Prevent Post-Inflammatory Hyperpigmentation
Here are some ways to prevent post-inflammatory hyperpigmentation:
- Don’t pick or squeeze pimples or rashes, as this increases inflammation and the risk of pigmentation
- Use gentle skincare products to avoid irritation
- Treat acne, eczema, or injuries early to reduce inflammation quickly
- Protect healing skin from sun exposure with sunscreen and hats
- See a dermatologist before trying aggressive treatments like peels or lasers
When to See a Dermatologist
If PIH is widespread, deeply pigmented, or resistant to over-the-counter treatments, it’s best to consult a board-certified dermatologist. They can provide a personalized treatment plan based on your skin type and the depth of pigmentation.
In Conclusion;
Post-Inflammatory Hyperpigmentation is common, but it’s also treatable and preventable with the right approach. The key is early intervention, gentle care, and consistent sun protection. With patience and proper guidance, your skin will definitely regain an even, healthy tone.
