Area of Science:

• Dermatology
• Pharmacology

Background:

• Severe acne often resists conventional therapies.
• Exploring novel treatments for recalcitrant acne is crucial.

Purpose of the Study:

• To evaluate the efficacy and safety of 13-cis retinoic acid in severe acne.
• To determine the optimal dosage for treating acne vulgaris.

Main Methods:

• A double-blind, dose-response study was conducted.
• Patients received 13-cis retinoic acid (0.1–1.0 mg/kg/day).
• Acne severity and sebum excretion were monitored.

Main Results:

• Sebum excretion decreased by 75% within 4 weeks.
• 80% acne severity improvement observed after 4 months.
• Side effects included skin and mucous membrane dryness.

Conclusions:

• 13-cis retinoic acid is a potent treatment for severe, treatment-resistant acne.
• The drug demonstrates significant efficacy with dose-related, tolerable side effects.
• No participants discontinued treatment due to adverse events.
