摘　　要：A 20-year-old man presented with for 6-month history of facial acne. He had erythema and red papules on the face secondary to BPO-induced contact dermatitis. He was administered topical corticosteroid. Contact dermatitis improved with this treatment, and he had red papules, comedones, prominent postinflammatory hyperpigmentation (PIH), postinflammatory erythema (PIE), erosions and erythema associated with acne vulgaris. He was subsequently treated with oral minocycline 100 mg/d and topical adapalene and ozenoxacin lotion once daily for 3 months. The inflammatory lesions and comedo subsided;however, PIH, PIE, atrophic scar and erosion persisted. During 3 months, the patient underwent chemical peeling using 20% glycolic acid (GA) and subsequent vitamin C iontophoresis twice at 1-month intervals. He showed almost disappearance of red papules and comedones but persistent PIH, PIE and erosion after 3 months of treatment. He was thereafter prescribed topical glyceryl-octyl-ascorbic acid/ascorbyl 2-phosphate 6-palmitate/DL-a-tocopherol phosphate complex for local application twice daily for 3 months. After 7 months of treatment, PIH, PIE, erosion and atrophic scar faded significantly with only trace residual erosions, atrophic scar and PIH. Subsequently, he was prescribed local application of 2% isostearyl-L-ascorbic acid gel vitamin C gel twice daily for 3 months. After 15 months, PIH, PIE, erosion and atrophic scar disappeared completely with significant improvement. Comprehensive sequential therapy resulted in significant improvement. It is suggested that medical treatment using systemic and topical antimicrobials and topical adapalene reduces inflammatory lesions and comedones initially. Subsequent chemical peeling using GA and vitamin C iontophoresis could improve PIH. These synergistic effects might have contributed to the significant improvement observed in this case. Comprehensive sequential treatment using chemical peeling, vitamin C iontophoresis and topical vitamin C can be a useful treatment strategy for PIHA 20-year-old man presented with for 6-month history of facial acne.
