How to Treat Post-Inflammatory Hyperpigmentation (PIH) Without Harsh Peels or Bleaching Agents

If you’ve ever had a breakout, scratch, or rash that left a dark mark behind — that’s post-inflammatory hyperpigmentation, or PIH. And while it’s not permanent, it can feel like it lingers far longer than the original concern.

At Platinum Cosmetics, we treat PIH with gentle, effective strategies that support your skin’s healing and clarity — without causing more inflammation in the process.

What Causes PIH?

PIH is your skin’s response to injury. When inflammation occurs — from acne, friction, burns, or skin conditions — melanocytes (pigment-producing cells) can overreact, leaving behind a flat, discoloured mark once the irritation subsides.

It can appear as:

  • Brown, red, or grey flat spots

  • Often worse after picking or scratching

  • Most common in darker skin tones (but can occur in all)

Unlike melasma, PIH is not hormonal — but it can still be difficult to treat if not approached gently.

How We Treat PIH in Clinic

At our Port Melbourne clinic, we offer safe and gradual treatments for fading PIH over time, including:

Laser therapy using Fotona’s light-based technology

  • Targets pigment and encourages even skin tone

  • Stimulates healthy skin turnover and collagen production

  • Safe for a range of skin tones when customised correctly

Skin rejuvenation treatments

  • Refine texture and reduce uneven tone

  • Improve brightness and clarity without stripping the skin

Custom facials

  • Provide hydration and barrier repair

  • Gently exfoliate with enzymes or acids, depending on your skin’s tolerance

Supporting Your Skin at Home

Your skin care routine plays a critical role in fading PIH and preventing recurrence:

  • SPF daily to prevent dark marks from deepening

  • Niacinamide to regulate pigment production

  • Azelaic acid or gentle exfoliants to support turnover

  • Vitamin C to brighten and defend

  • Avoid picking, harsh scrubs, or DIY peels — these worsen inflammation and can delay healing

How Long Does It Take to Fade?

PIH fades gradually — typically over 1 to 6 months depending on:

  • Your skin tone

  • Depth of the pigment

  • How soon treatment begins

  • Whether the skin remains calm and protected

The earlier we treat it — and the more consistent your skincare — the faster your results.
