How to Treat Post-Inflammatory Hyperpigmentation: Effective Solutions for Even-Toned Skin

Post-inflammatory hyperpigmentation (PIH) is a common skin concern that occurs after inflammation or injury to the skin. Whether from acne, eczema, cuts, or burns, PIH appears as flat, discolored patches ranging from pink to dark brown, depending on your skin tone. While not harmful, PIH can be frustrating and persistent—but with the right treatments and care, it is highly treatable.

What Is Post-Inflammatory Hyperpigmentation?

PIH happens when the skin produces excess melanin (the pigment responsible for skin color) in response to inflammation. This discoloration can remain long after the original blemish or injury has healed.

• On lighter skin tones, PIH may appear red or pink.

• On medium to dark skin tones, PIH often presents as brown or black spots.

PIH is different from other forms of hyperpigmentation like melasma or sun spots because it's caused by trauma or irritation, not UV exposure or hormonal changes.

What Causes PIH?

Common triggers include:

• Acne breakouts

• Over-exfoliation or chemical burns

• Insect bites or cuts

• Skin conditions like eczema or psoriasis

• Picking, scratching, or squeezing pimples

How to Treat PIH: Top Treatments That Work

1. Topical Ingredients

Several over-the-counter and prescription ingredients can help fade PIH over time:

• Niacinamide – Reduces pigmentation and soothes inflammation.

• Vitamin C – Brightens skin and reduces melanin production.

• Retinoids (Retinol, Tretinoin) – Speed up cell turnover to fade dark spots faster.

• Azelaic Acid – Anti-inflammatory and effective at reducing pigmentation, especially for acne-prone skin.

• Kojic Acid and Arbutin – Naturally derived skin lighteners that help reduce dark spots safely.

• Hydroquinone – A dermatologist-prescribed skin-lightening agent used in short-term treatments.

Tip: Always patch-test new ingredients to avoid irritation, especially if you have sensitive skin.

2. Sun Protection is Non-Negotiable

Sunscreen is essential. UV exposure can worsen PIH and slow down healing. Use a broad-spectrum SPF 30 or higher daily—even indoors. Look for formulas with zinc oxide or titanium dioxide for sensitive skin.

3. Professional Treatments

For more stubborn or deep pigmentation, dermatologists may recommend:

• Chemical Peels – Use acids like glycolic or salicylic acid to exfoliate and lighten dark patches.

• Laser Therapy – Targets pigmentation with controlled light energy. Best performed by a qualified professional.

• Microneedling – Stimulates collagen and helps reduce discoloration with consistent sessions.

What to Avoid

• Picking at your skin – This worsens inflammation and creates more PIH.

• Harsh scrubs and exfoliants – Can cause irritation and slow healing.

• DIY bleach or lemon juice remedies – These can damage the skin and worsen pigmentation.

Final Thoughts

Post-inflammatory hyperpigmentation can take time to fade, but with a consistent routine focused on skin barrier support, brightening agents, and sun protection, visible improvement is absolutely possible. If home treatments don’t show results after a few months, consult a dermatologist for stronger interventions tailored to your skin type.
