Dermatology

The skin is the largest human organ. In an adult of average build, its area is about 2 sq. m. It protects the body from the penetration of bacteria, microorganisms, viruses, pollution, and participates in the regulation of heat exchange. Skin diseases can be caused by both external and internal problems. Therefore, for effective treatment, dermatological preparations intended for external use can be combined with systemic drugs (for example, antibiotics).
