A – Z of Skin
Information for Skin, Hair and Nail Conditions
WHAT IS THE A-Z OF SKIN?
The A to Z of Skin information has been developed to help you understand more about common skin conditions and problems, and how these may be treated.
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 currently under development. Please check back on a regular basis for updates and the addition of new topics.
