How We Treat Post-Inflammatory Hyperpigmentation (PIH): A Step-by-Step Guide

Posted August 07, 2025 in laser treatments face

Post-inflammatory hyperpigmentation (PIH) is one of the most common skin concerns we treat at Mountcastle Medical Spa & Laser Center. Whether it’s triggered by acne, laser treatments, or minor injuries, PIH can leave stubborn dark spots—especially on deeper skin tones.

The good news? With a medically backed and personalized plan, PIH is highly treatable.

Here’s our step-by-step approach to achieving clearer, more even-toned skin.


Step 1: Comprehensive Skin Assessment

Every treatment begins with a one-on-one consultation at our Ashburn med spa with one of our licensed providers—such as our award-winning aesthetic injectors or expert aestheticians.

We evaluate:

  • Fitzpatrick skin type
  • The source and depth of pigmentation
  • Recent skincare products or treatments
  • Whether inflammation is still present (active acne, eczema, etc.)

Step 2: Prep the Skin with Medical-Grade Skincare

Before in-office treatments, we prime your skin using a customized skincare regimen. This allows the skin barrier to heal and prepares it to respond better to pigment correction.

Step 3: In-Office Treatments to Fade PIH

We tailor your treatment plan based on your skin’s tone, sensitivity, and lifestyle. Some of the best options for PIH include:

Chemical Peels

We offer several options, including:

  • The Perfect Derma™ Peel: A medium-depth peel safe for all skin types
  • Mandelic or lactic acid peels for sensitive or darker skin tones

These peels work by gently exfoliating the top layers of skin and targeting melanocytes (the pigment-producing cells).

Microneedling with PRF or Brightening Serums

Microneedling triggers collagen production and allows for deeper penetration of targeted serums. At Mountcastle, we often enhance this with:

  • PRF (Platelet-Rich Fibrin) to naturally speed up healing
  • Brightening serums rich in tranexamic acid or vitamin C

Laser Treatments (For Select Skin Types)

Laser treatments are selected with extreme care, especially for skin of color. Safety always comes first.


Step 4: Post-Treatment Aftercare & Sun Protection

After any in-office treatment, your skin will be more sensitive to UV exposure. Proper aftercare is essential to prevent rebound pigmentation.

We recommend:

  • Daily use of mineral-based SPF 50, like Colorescience Total Protection
  • No exfoliating or retinoids for at least 5–7 days
  • Avoiding direct sun, including through car windows or overcast days

Pro tip: Wearing a wide-brimmed hat and using a tinted mineral sunscreen (external link) offers added protection for melanated skin.


Step 5: Maintenance & Results

Results begin to appear after 4–6 weeks of treatment and continue to improve with consistent skincare and maintenance. For long-term results, we may recommend:

Most patients see significant improvement in tone, clarity, and confidence.
