title: 13-cis retinoic acid and acne.
abstract: Patients with very severe acne which had not responded to conventional treatment were given 13-cis retinoic acid (0.1 mg-1.0 mg/kg body-weight) in a double-blind dose response study. Sebum excretion rate was reduced by 75% at 4 weeks, and all patients had an 80% improvement in their acne severity after 4 months treatment. There were dose-related side-effects, particularly dryness of the skin and mucous membranes. No patient wished to stop treatment.
