Adapalene Gel for Acute Radiation-Induced Skin Injury

his study aims to evaluate whether adapalene gel is effective and safe for treating acute radiation-induced skin injury in adults receiving radiotherapy. Researchers will compare adapalene gel with Biafine to determine whether adapalene gel reduces radiation-induced skin injury and improves symptoms. The main questions are: Does adapalene gel reduce the severity of acute radiation-induced skin injury compared with Biafine, and what medical problems or adverse events occur in participants using adapalene gel? Participants will apply adapalene gel or Biafine topically every day throughout the course of radiotherapy, visit the clinic every 5 days for examinations and tests, and record their symptoms and any adverse reactions during use.
