Post-inflammatory hyperpigmentation (PIH) happens when a breakout, scratch, or irritation leaves behind a dark mark even after the initial issue has healed. It’s especially common in deeper skin tones—but it can affect anyone.
While PIH isn’t permanent, it’s persistent. And without the right approach, it can linger for months—or even longer.
Common Causes of PIH:
-
Acne lesions
-
Picking or popping pimples
-
Skin irritation from harsh products
-
Burns or rashes
-
Insect bites
SPF: The Foundation of Any PIH Routine
Fading PIH without sun protection is like trying to mop a floor while the faucet is still running. UV rays and visible light trigger melanocytes (the pigment-producing cells), keeping the cycle going.
Why I Recommend Zinc-Based Sunscreens for PIH
Pavise Dynamic Age Defense SPF 30 features 15% zinc oxide, a mineral filter that protects against UVA, UVB, and visible light. Zinc is ideal for reactive skin—it doesn’t trigger inflammation or absorb into the skin.
Busting Myths About PIH and Sun Protection
"It’s winter—I don’t need sunscreen." False. UVA rays are present year-round and penetrate clouds and windows. They’re a top contributor to lingering pigmentation.
"I’ll just use my foundation with SPF." You’d need to apply seven times the amount of foundation you normally wear to get enough protection. SPF should always be its own step.
"Sunscreen makes my skin greasy." Not all sunscreens are created equal. Pavise Dynamic Age Defense SPF 30 has a weightless feel and helps reduce redness and flare-ups thanks to its anti-inflammatory ingredients.
Key Ingredients That Support PIH-Prone Skin
1. Zinc Oxide (15%)
Provides physical protection against UVA, UVB, and visible light—essential for preventing pigment from deepening.
2. Tranexamic Acid + Licorice Root Extract
These help inhibit tyrosinase, the enzyme that drives pigment production. Both also calm inflammation, which is key to preventing new marks.
3. Niacinamide
One of my favorite actives—it supports the skin barrier, reduces redness, and helps even out skin tone over time.
4. Antioxidants
-
Astaxanthin + Pine Bark: Defend against free radical damage.
-
Milk Thistle + Vitamin E: Soothe skin and reduce inflammation.
What I See in My NYC Clinic
Clients with PIH are often doing everything right—acids, retinoids, brightening serums—but not seeing results because they skip or underuse SPF. Once we add a daily mineral sunscreen like Pavise Dynamic Age Defense SPF 30, the difference is noticeable within weeks.
This product doesn’t just block light. It actively supports healthy skin with barrier-repairing squalane, calming bisabolol, and skin-tone-evening peptides.
Best Practices for SPF and PIH
-
Use a full 1/2 teaspoon for face and neck.
-
Apply daily—even indoors or when it’s cloudy.
-
Reapply every 2 hours if you’re outside.
-
Be consistent. Even occasional lapses can delay progress.
