Melasma vs PIH: How to Tell the Difference (and Fix It)- Gluta One
Share
Skin discoloration can be frustrating and often confusing. Two of the most common conditions people mix up are melasma and post-inflammatory hyperpigmentation (PIH). While both cause dark spots and uneven skin tone, their causes, appearance, and treatment options are quite different. Knowing how to tell them apart is the first step to achieving clearer, brighter skin.
In this guide, we’ll break down melasma vs post inflammatory hyperpigmentation, why they occur, and the most effective ways to treat and prevent them.

What is Melasma?
Melasma is a chronic skin condition that causes brown or gray-brown patches, usually on areas of the face exposed to the sun. It is often called the “mask of pregnancy” because it commonly appears in pregnant women due to hormonal changes.
Causes of Melasma:
-
Hormonal fluctuations (pregnancy, birth control pills, hormone therapy)
-
UV radiation exposure
-
Genetic predisposition
-
Heat and infrared light
Appearance of Melasma:
-
Symmetrical patches on the cheeks, forehead, nose bridge, or upper lip
-
Larger, diffused patches rather than sharp dark spots
-
Worsens with sun exposure

What is Post-Inflammatory Hyperpigmentation (PIH)?
PIH occurs when the skin overproduces melanin as a response to injury or inflammation. Unlike melasma, it’s not primarily driven by hormones.
c of PIH:
-
Acne breakouts
-
Eczema or dermatitis
-
Cuts, burns, or bug bites
-
Aggressive cosmetic treatments (chemical peels, laser, waxing, etc.)
Appearance of PIH:
-
Dark spots or patches at the site of injury
-
Can be red, brown, or even purple, depending on skin tone and depth
-
Irregular and spotty, unlike melasma’s symmetrical patches

Melasma vs PIH: Key Differences

👉 When comparing melasma vs post inflammatory hyperpigmentation, the key difference is that melasma is hormonally and sun-driven, while PIH is linked to trauma or irritation of the skin.
How to Treat Melasma
Since melasma is more complex and stubborn, it requires consistent and careful management:
-
Sun Protection – Broad-spectrum sunscreen (SPF 50+) is a must every single day.
-
Topical Ingredients:
-
Hydroquinone (skin-lightening agent)
-
Azelaic Acid (safe for pregnancy)
-
Tranexamic Acid
-
Niacinamide
-
Retinoids (not safe during pregnancy)
-
Hydroquinone (skin-lightening agent)
-
Oral Supplements: Glutathione and Vitamin C may help even out skin tone.
-
Professional Treatments:
-
-
Chemical peels
-
Microneedling with brightening serums
-
Laser therapies (only under dermatologist supervision)
-
Chemical peels
⚠️ Melasma is chronic—management is about controlling it, not permanently “curing” it.
How to Treat PIH
The good news about PIH is that it usually fades with time. However, the process can be sped up with the right treatments:
-
Topical Ingredients:
-
Alpha Arbutin
-
Vitamin C
-
Glycolic Acid (gentle exfoliation)
-
Kojic Acid
-
Retinoids
-
Alpha Arbutin
-
Daily Sunscreen: Prevents spots from becoming darker.
-
Lifestyle Care: Avoid picking acne or scratching skin to reduce further pigmentation.
-
Professional Options: Chemical peels, microdermabrasion, and lasers can accelerate fading.
Can You Have Both Melasma and PIH?
Yes! Some people have melasma patches and PIH from acne scars or other skin damage. This makes treatment more challenging and requires a combination approach, often guided by a dermatologist.
Preventing Future Pigmentation
-
Apply sunscreen daily, even indoors.
-
Use protective hats or umbrellas in the sun.
-
Maintain a gentle skincare routine to avoid irritation.
-
Treat acne early to reduce the risk of PIH.
- For melasma-prone individuals, be cautious with heat, sun, and hormonal triggers.

Final Thoughts
Melasma and PIH may look similar, but understanding their differences is crucial for the right treatment. Melasma is hormonally and sun-triggered, usually in symmetrical patches, while PIH is caused by skin trauma and appears as irregular spots.
With the right skincare ingredients, sun protection, and professional guidance, both conditions can be managed effectively. If pigmentation is impacting your confidence, consulting a dermatologist is the best step toward clearer skin.
✅ Takeaway: When it comes to melasma vs post inflammatory hyperpigmentation, melasma is harder to control but manageable with consistent care, while PIH usually fades faster with targeted treatments. Both need sun protection as the first line of defense.
FAQ’s
What is the main difference between melasma and post-inflammatory hyperpigmentation (PIH)?
A: Melasma is mainly caused by hormonal changes and sun exposure, appearing as symmetrical patches on the face. PIH happens after skin trauma (like acne or cuts) and appears as irregular dark spots where the skin was injured.
Q2. Can melasma and PIH occur at the same time?
A: Yes. Some people develop melasma patches along with PIH marks from acne or other skin issues. In such cases, treatment requires a combined approach with dermatologist guidance.
Q3. Which condition is harder to treat: melasma or PIH?
A: Melasma is usually more stubborn and chronic, requiring long-term management with sunscreen, serums, and professional treatments. PIH often fades with time and responds well to brightening ingredients like glycolic acid, alpha arbutin, and vitamin C.
Q4. How do Gluta One products help with melasma and PIH?
A: Gluta One serums and creams contain glutathione, azelaic acid, alpha arbutin, kojic acid, and vitamin C—all proven ingredients for fading pigmentation. For melasma, the Anti-Pigmentation Serum and Melasma Treatment Serum work best, while for PIH, the Face Serum with Alpha Arbutin + Kojic Acid helps lighten dark spots effectively.
Q5. Do I need sunscreen if I’m already using Gluta One products?
A: Absolutely. Sunscreen is essential for both melasma and PIH. Without sun protection, even the best treatments may fail or pigmentation may worsen.
Q6. How long does it take to see results with Gluta One serums for pigmentation?
A: Visible improvements usually appear within 4–6 weeks of consistent use, depending on skin type and severity. However, melasma requires longer management compared to PIH.
Q7. Are Gluta One products safe for all skin types?
A: Yes, Gluta One formulations are dermatologically tested, safe for most skin types, and enriched with antioxidants. Sensitive skin users should always start with a patch test before full application.
