What Is Post-Inflammatory Hyperpigmentation?
Post-inflammatory hyperpigmentation (PIH) treatment in Seoul helps improve dark spots, acne marks, skin discoloration, uneven skin tone, and pigmentation left behind after inflammation or skin injury. At Dami Clinic Yeouido, PIH treatment plans are customized according to skin type, pigmentation severity, underlying causes, and long-term skin rejuvenation goals.
Post-inflammatory hyperpigmentation is particularly common in Asian skin and often develops after acne, eczema, dermatitis, skin irritation, burns, or cosmetic procedures. Modern dermatology offers advanced treatment options including Pico Laser, chemical peels, medical skincare, RF Microneedling, skin boosters, and pigment-targeting therapies to improve skin clarity and restore a more even complexion.
International patients benefit from English-speaking consultations, comprehensive skin analysis, and treatment protocols specifically designed for Asian and international skin types.
Post-inflammatory hyperpigmentation (PIH) is one of the most common pigmentation concerns seen in dermatology clinics. Although the original inflammation may have resolved, the discoloration that remains can persist for months and significantly affect overall skin appearance.
Post-inflammatory hyperpigmentation is a form of skin discoloration that develops after inflammation stimulates excess pigment production.
PIH may appear as:
The condition is caused by excess melanin production rather than permanent skin damage.
- Brown spots
- Dark acne marks
- Grayish discoloration
- Uneven skin tone
- Localized pigmentation patches
