A-Z OF SKIN
Search our A to Z of Skin to find out more about common skin conditions and problems, their symptoms, causes and how they are diagnosed and treated. You can search by both common and medical names, or by medicine or treatment name.
Both common and medical names have been included to help your search, as well as the names of medications and treatments. There are also a number of cosmetic topics which explain the latest treatments for cosmetic concerns related to the skin. Many College dermatologists have contributed to the information on this site.
The process has been overseen by a committee of dermatologists to ensure that the final versions are both accurate and user friendly. Particular thanks go to Dr Pam Brown, Dr Peter Berger, Dr Davin Lim, Dr Michelle Rodrigues, Dr Yin Vun, Conjoint Associate Prof Orli Wargon and Dr Eleni Yiasemides (Chair). The A to Z information is regularly updated. Please check back on a regular basis for updates and the addition of new topics.
