Second-Degree Burns Following Intense Pulsed Light Therapy in a Patient With Fitzpatrick Skin Type IV: A Case Report

Intense pulsed light (IPL) therapy is widely used in cosmetic dermatology for the treatment of unwanted hair, vascular lesions, pigmentary disorders, and acne-related sequelae. We present a case of a male in his late 20s with Fitzpatrick skin type IV who sustained second-degree burns following IPL therapy for post-acne erythema performed by a non-medical operator. The patient developed erythema, blisters, and desquamation. He was treated with oral medications (acyclovir and cephalexin), corticosteroid ointment, and medicated powder dressings. Subsequent treatment included light-emitting diode (LED) therapy, picosecond laser sessions, and topical depigmenting agents. Significant improvement was noted after four months with minimal residual hyperpigmentation. This case highlights the risks associated with IPL treatment administered by untrained personnel and underscores the importance of professional oversight and patient-specific parameter adjustments.
