The textbook "Histological Study of Skin Changes in Photoaging" by Noor Publishing offers a comprehensive analysis of the histological changes in the skin caused by photoaging. It highlights the differences between sun-exposed and sun-protected skin, particularly in women, and examines the effects of UV radiation on skin structure. The study, conducted in 2007 in Cairo, Egypt, provides valuable insights into the factors influencing skin appearance, including genetic, health-related, and environmental aspects. The author, Dalia Alaa El Waseef, presents detailed histological findings that illustrate the dangers of photoaging and the increased risk of skin cancer. This book is an important resource for professionals in the fields of medicine and nursing who deal with dermatological changes and their causes.
