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.
