Dark Marks That Remain After Acne or Irritation? That’s PIH
Post-Inflammatory Hyperpigmentation (PIH) is one of the most common pigmentation concerns we treat at Mollie Elise Aesthetics.
Clients often describe dark marks left behind after breakouts, ingrown hairs, eczema flare-ups, waxing irritation or picking.
PIH is not scarring — it’s pigment left behind from inflammation. And with the right treatments, it can fade significantly.
What Is PIH?
PIH occurs when inflammation triggers excess melanin production, leaving behind:
- Dark marks on the skin
- Brown or purple marks after acne
- Flat dark patches
- Pigmented areas after irritation
- Marks that linger for months
- Areas that darken with sun exposure
It is especially common on medium to deeper skin tones.
What Causes PIH?
Common triggers include:
- Acne (most common)
- Picking or squeezing spots
- Rashes or dermatitis
- Eczema
- Ingrown hairs
- Waxing or friction
- Harsh products
- Burns or irritation
- Inflamed skincare reactions
PIH is worsened by UV exposure and inflammation.
Consultation: Understanding Your PIH Pattern
We assess:
- Pigment depth
- the amount of dark marks or darkened areas on the skin
- Your skin tone
- Acne history
- Whether the skin is still inflamed
- Sensitivity levels
- Skincare triggers
- Lifestyle factors (sun exposure, picking habits)
This ensures treatment is appropriate, safe and targeted.
Chemical Peels for PIH
Chemical peels are one of the fastest and safest ways to fade PIH.
They help to:
- Lift pigmented cells
- Brighten uneven tone
- Reduce acne marks
- Improve skin texture
- Stimulate new, clearer skin
A course typically gives the best results.
Microneedling for PIH & Textural Improvement
Microneedling is ideal once active inflammation has settled. It:
- Speeds up pigment fade
- Stimulates fresh collagen
- Smooths texture from old breakouts
- Improves overall clarity
- Reduces residual redness
Not suitable during active acne.
PureDerma (RF Microneedling) for Stubborn PIH
For deeper, long-standing or textured PIH, PureDerma helps by:
- Stimulating stronger collagen production
- Im proving texture + tone
- Supporting faster pigment cell turnover
It is particularly useful for PIH combined with indented acne scarring.
HydroFacial (Brightening Protocol)
A HydroFacial can help:
- Remove dull dead skin
- Brighten pigmentation
- Improve hydration
- Smooth texture
- Enhance penetration of brightening serums
Perfect for early-stage PIH or maintenance.
Polynucleotides for Inflammation Reduction
Polynucleotides help reduce the inflammation that causes PIH, making them ideal when PIH is linked to:
- Acne
- Picking
- Sensitivity
- Barrier damage
- Eczema
They also support deeper skin repair and long-term clarity.
Medical-Grade Skincare for PIH
Homecare is essential for fading PIH.
We prioritise:
- Pigment inhibitors
- Retinol (when appropriate)
- Vitamin C
- Gentle exfoliation
- Barrier support
- Daily SPF
AlumierMD formulas help prevent PIH from re-darkening and minimise new marks.
