Treatments for post-inflammatory hyperpigmentation (PIH) focus on fading brown, gray-brown, or darker marks that remain after acne, irritation, or other skin inflammation has healed. Gangnam WOOA Skin Clinic in Seoul provides personalized PIH treatment including selected pigmentation lasers, skin-brightening treatments, exfoliation-based care, skin-quality treatments, and combination therapy for international patients.

What Is Post-Inflammatory Hyperpigmentation?

Post-inflammatory hyperpigmentation, commonly called PIH, is discoloration that develops after inflammation or injury to the skin.

It may appear as:

• Brown acne marks
• Dark spots after pimples
• Gray-brown marks
• Uneven pigmentation
• Dark patches
• Post-acne discoloration
• Uneven skin tone

PIH is usually a change in skin color rather than a permanent textural scar.

What Causes Post-Inflammatory Hyperpigmentation?

Inflammation can stimulate excess melanin production, leaving darker pigmentation after the original skin problem resolves.

Common triggers include:

• Acne
• Picking or squeezing pimples
• Skin irritation
• Inflammatory skin conditions
• Scratches or minor injuries
• Burns
• Aggressive cosmetic treatments
• Insect bites

Sun exposure can make existing pigmentation appear more noticeable and contribute to prolonged discoloration.

Post-Acne Hyperpigmentation

Acne is one of the most common causes of PIH.

After an inflamed pimple heals, a flat brown or darker mark may remain.

Patients with recurring acne can develop multiple marks across the:

• Cheeks
• Forehead
• Chin
• Jawline
• Temples

Controlling active acne is important for preventing new pigmentation.

Best Treatments for Post-Inflammatory Hyperpigmentation

Depending on pigmentation depth, skin type, and cause, treatment may include:

Pigmentation Laser Treatments – for selected brown or dark marks
Laser Toning – for appropriate pigmentation patterns
Exfoliation-Based Treatments – for selected superficial pigmentation
Topical Skin Care – for pigment control and skin renewal
Skin-Quality Treatments – to support overall skin condition
Combination Treatments – when pigmentation occurs with acne, redness, or texture concerns

Not every dark spot should be treated with the same laser.

Laser Treatment for PIH

Selected laser treatments may help improve persistent post-inflammatory pigmentation.

Treatment planning should consider:

• Skin tone
• Pigmentation depth
• Cause of inflammation
• Active acne
• Skin sensitivity
• Previous treatment history

Overly aggressive treatment can sometimes worsen pigmentation, making appropriate device selection and settings important.

Laser Toning for Post-Acne Pigmentation

Laser toning may be considered for selected pigmentation concerns depending on skin type and diagnosis.

The goal is gradual improvement rather than excessively aggressive pigment removal.

Multiple sessions may be recommended depending on the extent and depth of pigmentation.

Exfoliation for PIH

Professionally selected exfoliation-based treatments may help improve superficial pigmentation and skin turnover.

Depending on skin condition, they may also help with:

• Clogged pores
• Acne
• Rough texture
• Dullness
• Uneven tone

Treatment strength should be customized to avoid unnecessary irritation.

PIH vs Post-Acne Redness

These conditions are commonly confused.

Post-Inflammatory Hyperpigmentation (PIH) usually appears brown, gray-brown, or darker than the surrounding skin.

Post-Inflammatory Erythema (PIE) usually appears red, pink, or reddish-purple.

Because one is primarily pigment-related and the other is more vascular, they may require different treatment approaches.

PIH vs Acne Scars

Post-inflammatory hyperpigmentation is not the same as an acne scar.

PIH is generally a flat change in skin color.

Acne Scars involve changes in skin texture, such as depressions or raised tissue.

A patient may have pigmentation and acne scars at the same time.

PIH in Darker Skin Tones

PIH can be particularly noticeable and persistent in skin types with greater melanin activity.

Treatment should be carefully customized because overly aggressive lasers, peels, or irritation can potentially cause additional pigmentation.

A gradual approach may be preferable for selected patients.

Can PIH Fade Naturally?

Yes. Some post-inflammatory pigmentation gradually fades as the skin naturally renews.

However, the process may take months, and deeper or repeatedly triggered pigmentation may persist longer.

Professional treatment may help accelerate improvement in appropriate patients.

How Long Does Post-Inflammatory Hyperpigmentation Last?

There is no single timeline.

How quickly PIH fades depends on:

• Pigmentation depth
• Skin tone
• Severity of inflammation
• Sun exposure
• Recurrent acne
• Skin irritation
• Individual healing response

Deeper pigmentation generally takes longer to improve.

Does Sunscreen Help PIH?

Sun protection is an important part of PIH management.

UV exposure can stimulate additional pigment production and make existing dark marks more noticeable.

Daily broad-spectrum sunscreen can help protect treatment results and reduce further darkening.

Can Acne PIH Come Back?

Treated pigmentation may improve, but new marks can develop if acne continues.

Long-term management should therefore focus on both:

Treating Existing Pigmentation

and

Preventing New Inflammatory Acne

This approach can provide better overall improvement in skin tone.

Treating PIH, PIE and Acne Scars Together

Many patients have several post-acne concerns simultaneously.

A personalized plan may need to address:

Brown Marks / PIH – pigmentation-focused treatment
Red Marks / PIE – vascular-focused treatment
Acne Scars – texture and collagen-remodeling treatment
Active Acne – acne control to prevent new marks

These treatments may be performed in stages.

Korean PIH Treatment

Korean pigmentation treatment often combines accurate diagnosis with gradual, skin-type-appropriate treatment.

A personalized program may include:

Pigmentation Lasers for selected dark marks
Laser Toning for appropriate pigmentation
Exfoliation Treatments for superficial pigment and congestion
Acne Treatment to prevent new PIH
Skin-Quality Care to support healthy-looking skin

The goal is clearer, more even-looking skin without unnecessarily irritating the skin.

Combination Treatment for Post-Inflammatory Hyperpigmentation

A personalized treatment plan may consider:

Pigmentation Laser Treatments for selected PIH
Laser Toning for appropriate pigmentation patterns
Exfoliation Treatments for superficial discoloration
Acne Treatment for ongoing breakouts
Skin-Quality Treatments for overall rejuvenation

Not every patient requires every procedure.
