Purpura following laser hair removal: a case report.

Laser hair removal (LHR) is a reliable and safe technique for the long-term reduction of unwanted hair. Common adverse effects involve momentary discomfort, transient erythema, and perifollicular edema, while the occurrence of purpura is infrequent. A 25-year-old Greek woman with skin type IV developed purpura on her lower extremities 48 hours after her first alexandrite laser session. A positive response to a laser hair removal provocation test was identified, aiding in diagnosis. Treatment with orally administered corticosteroids and antihistamines led to complete resolution within 7 days. Purpura following laser hair removal is a rare side effect, and its underlying cause remains unclear. Physician awareness of such adverse reactions can streamline patient care, reducing the need for unnecessary tests and offering improved management protocols.
