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.

Acne keloidalis nuchae (AKN)
Acne keloidalis nuchae (AKN) is a chronic inflammatory condition that affects hair follicles on the back of the neck. AKN is most commonly seen in men of African-Caribbean background but it is also seen in those of Hispanic, Asian, Middle Eastern and Mediterranean backgrounds. In rare cases, it may also be see in Caucasians. Whilst this condition mostly affects men, women may be affected in some cases (the ratio of affected men to women is 20:1). The term AKN is misleading because the condition does not form true keloid scars and is not associated with acne.More
