Best Serum for Post-Acne Marks: Stop Relapse Pigmentation Caused by Sun Exposure

Many acne marks fade and then return darker after sun exposure—this relapse pigmentation is extremely common in India. Learn how CLARIV Anti-Acne & Anti-Pigmentation serums are Best Serum for Post-Acne Marks and help break this cycle for clear, even skin.

Most people think post-acne marks fade permanently.
But in India, this is rarely the case.

Here’s the REALITY:

👉 Acne marks often return darker after even mild sun exposure.
👉 Even if marks have faded 60–80%, stepping outside can darken them again.
👉 UV + heat + pollution trigger a relapse of pigmentation.

This phenomenon is known as:

**“Relapse Pigmentation”

(or “Re-Tanning of Acne Marks”)**

And it’s one of the biggest reasons acne marks in India seem “never-ending.”

Today, we break down why this happens and how to treat it effectively using:

Both formulations include clinically backed ingredients, as seen in product labels.
The Anti-Acne Serum contains 2% Salicylic Acid, 5% Niacinamide & 5% Azelaic Acid

and

The Anti-Pigmentation Serum contains 2% Kojic Acid, 2% Alpha Arbutin, 3% Tranexamic Acid & 5% Niacinamide .

Why Acne Marks Come Back After Sun Exposure

Here’s what actually happens:

1. Indian Skin Produces More Melanin

Melanin is activated aggressively in hot climates → even small UV exposure darkens old marks.

2. Heat Alone Can Darken Faded Marks

You don’t need direct sunlight — even stepping outside in heat triggers pigmentation.

3. Acne Marks Are “Weak Spots”

These areas are already inflamed → they pigment 3–5x faster.

4. Pollution Traps Heat in the Skin

This worsens relapse pigmentation.

5. UVA Exposure Through Windows

Office, home, car windows = tanning without realizing it.

This is why acne marks fade…
and then suddenly look DARKER again.
To break this cycle, you need a two-serum strategy.

The Only Effective Solution: Treat Redness + Pigmentation Separately

Post-acne marks come in two types:

🔴 Red Marks (PIE)

Inflammation + irritation
Best treated with anti-acne ingredients.

🟤 Brown Marks (PIH)

Melanin overproduction
Best treated with anti-pigmentation ingredients.

To prevent relapse pigmentation, both issues must be targeted.

CLARIV offers the perfect pair.

1️⃣ CLARIV Anti-Acne Serum – Stops Red Marks From Turning Brown

According to the label, this serum contains:

  • 2% Salicylic Acid for deep pore cleaning

This serum is ideal for:

  • Fresh acne

  • Red marks

Why it matters for relapse pigmentation:

These ingredients:

✔ Reduce melanin

This makes it one of the most powerful formulas for acne mark correction.
