Post-Inflammatory Hyperpigmentation Treatment in Gangnam
Post-Inflammatory Hyperpigmentation Treatment in Gangnam
Post-inflammatory hyperpigmentation, or PIH, refers to flat brown, gray, or dark marks that remain after acne, irritation, eczema, or other skin inflammation has healed.
It is especially common in medium to darker skin tones and can last much longer than the original breakout. Unlike a true acne scar, PIH is a change in skin color rather than permanent damage to the skin’s structure.
What Causes PIH?
PIH develops when inflammation stimulates excess melanin production.
Common triggers include:
- Acne
- Picking or squeezing pimples
- Skin irritation
- Eczema
- Burns or injuries
- Aggressive cosmetic treatments
Sunlight and visible light can also make existing pigmentation more noticeable or persistent.
Treat Active Acne First
If acne is still appearing, treating only the dark marks may lead to disappointing results because new pigmentation will continue to form.
For acne-related PIH, treatment often focuses on controlling breakouts while gradually fading existing marks.
Topical retinoids, benzoyl peroxide, and other acne treatments may therefore be part of the overall plan.
Topical Treatments for PIH
Not every patient needs laser treatment.
Depending on the skin condition, dermatologists may recommend ingredients such as:
- Azelaic acid
- Retinoids
- Hydroquinone
- Other pigment-reducing skincare
Azelaic acid can be particularly useful because it may help both acne and the dark marks that remain afterward.
Laser Treatment in Gangnam
Gangnam clinics offer several laser options for persistent pigmentation, including pico lasers and pigment-focused laser toning.
Laser treatment may help selected patients, but PIH requires careful settings.
A systematic review of PIH treatment in darker skin tones found improvement with laser therapy in many patients, while also reporting cases where pigmentation became worse after treatment.
For this reason, stronger laser settings are not automatically better.
Chemical Peels
Gentle chemical peels may also be considered for superficial PIH.
They can help with:
- Mild post-acne pigmentation
- Uneven tone
- Rough texture
- Congested skin
However, aggressive peeling can create additional inflammation and potentially cause more pigmentation, particularly in sensitive or darker skin.
PIH Treatment for Darker Skin Tones
People with darker skin tones are generally more likely to develop persistent PIH after inflammation.
Before treatment, tell the clinic if you:
- Develop dark marks easily
- Have previously experienced pigmentation after lasers
- Have sensitive skin
- Recently tanned
- Have active acne or eczema
A gradual treatment approach is often safer than aggressively trying to remove pigmentation in one session.
How Long Does PIH Take to Fade?
PIH usually improves gradually.
Some superficial marks may fade over several months, while deeper or more persistent pigmentation can take considerably longer.
Treatment can help accelerate improvement, but patients should not expect every dark mark to disappear after a single laser session.
How Can You Prevent New Dark Marks?
Preventing new inflammation is an important part of PIH treatment.
Helpful habits include:
- Treating acne early
- Avoiding picking or squeezing pimples
- Using gentle skincare
- Avoiding unnecessary irritation
- Wearing sunscreen consistently
- Following prescribed acne treatment
Early acne treatment can reduce the likelihood of additional dark marks developing.
What Should International Patients Ask?
Before booking PIH treatment in Gangnam, ask:
- Is this PIH or another type of pigmentation?
- Do I still have active acne?
- Do I actually need laser treatment?
- Which treatment is safest for my skin tone?
- How many sessions may be required?
- Could treatment temporarily worsen pigmentation?
- What skincare should I use afterward?
- What downtime should I expect?
A proper diagnosis is more important than choosing a pigmentation package based only on price.
Final Thoughts
Post-inflammatory hyperpigmentation is common after acne and other forms of skin inflammation, particularly in pigmentation-prone skin.
Treatment in Gangnam may include topical medication, acne control, gentle chemical peels, or carefully selected laser procedures.
For international patients, the safest approach is usually to control the underlying inflammation first and improve pigmentation gradually.
With appropriate treatment, consistent sun protection, and patience, PIH can become noticeably lighter and the overall skin tone more even.
