Targeting Post-Inflammatory Hyperpigmentation: A Gentle Retinol + Peptide Strategy

Post-inflammatory hyperpigmentation (PIH) shows up as dark spots left behind after breakouts, bug bites, or irritation. It’s especially common in medium to deep skin tones, and it tends to stick around longer than most people expect.

In my clinical work, the most common triggers I see for PIH include:

• Acne, especially when picked or popped

• Over-exfoliating or using harsh skincare

• Sun exposure while skin is healing

• Heat and inflammation from treatments or environmental stress

Unlike melasma, PIH isn’t hormone-driven—but it still requires a thoughtful and steady approach to fade effectively.

Non-Product Tips for Minimizing PIH

Before we talk about products, let’s get the basics right. Here’s what I advise clients to do to reduce and prevent PIH:

• Absolutely no picking—this is the #1 cause of long-lasting spots

• Avoid over-exfoliation, especially with physical scrubs or harsh acids

• Wear SPF daily, even indoors or during cloudy weather

• Use calming, non-irritating skincare to reduce inflammation

Building habits that reduce inflammation and support healing is the foundation. Then we add in targeted products to fade existing pigment.

Why I Recommend Face Reality Retinol Peptide Serum for PIH

When treating PIH, I’m always thinking about how to gently nudge the skin to renew itself without causing more irritation. That’s where this serum comes in.

1. Retinol for Resurfacing Without the Drama

At 0.55%, the retinol in this formula is strong enough to increase cell turnover—helping pigmented cells rise to the surface and shed—but gentle enough for most acne-prone or sensitive skin.

Retinol helps with:

• Fading dark spots over time

• Smoothing uneven texture

• Preventing future breakouts that cause new PIH

It’s time-released and paired with calming hydrators to avoid the peeling or redness that usually comes with stronger retinoids.

2. Peptides to Rebuild and Calm

Fading pigment isn’t just about exfoliation—it’s also about creating an environment where the skin can heal. That’s where peptides shine:

• Palmitoyl Tripeptide-38 supports collagen production, helping reduce texture and shadowing

• N-Prolyl Palmitoyl Tripeptide-56 Acetate promotes regeneration, making the skin more resilient

These ingredients help fortify the skin’s structure, so it holds onto less pigment when irritated.

3. Barrier-Friendly Moisturizers and Soothers

If a PIH treatment dries out or stings the skin, we’re back to square one. This formula includes:

• Glycerin + Caprylic/Capric Triglyceride to hydrate without clogging pores

• Cyclodextrin + Pentylene Glycol to deliver retinol slowly and gently

These ingredients help maintain a healthy moisture balance and reduce the risk of flaking or irritation.

My Step-by-Step Protocol for PIH Clients

Here’s how I typically introduce Face Reality Retinol Peptide Serum in a routine:

1. Start 2–3 nights per week, after cleansing and applying a calming mist or serum

2. Use a pea-sized amount over the face (don’t spot treat—PIH is best handled globally)

3. Follow with moisturizer to lock in hydration

4. Always use sunscreen during the day, no exceptions

5. After 2–3 weeks, we can gradually increase to nightly use if the skin tolerates it

What Results Can You Expect?

PIH takes time to fade, but with consistent use and smart sun protection, you can absolutely see results.

In my clinic, I’ve seen:

• Noticeable fading within 6–8 weeks

• Smoother texture and reduced shadowing in 8–12 weeks

• Fewer new dark marks with consistent use and breakout prevention

Clients who are patient, consistent, and sun-safe always see the best results.

Tips for Preventing Future PIH

• Treat breakouts early—don’t wait until they scar

• Don’t touch healing spots, even if they scab

• Be cautious with in-office treatments if you’re prone to pigment

• Look for calming ingredients like panthenol, allantoin, or beta-glucan in your routine
