Never heard of him but I found this and reference to Ziering:
"Dr Camilo Diaz is a Consultant Dermatologist based in Birmingham.
Dr Diaz deals with all aspects of General Dermatology but special interests include Skin Cancer and in particular Dermatologic Surgery, where he routinely undertakes complex reconstructions after removing skin cancers, with great cosmetic results.
Cosmetic Dermatology and non invasive procedures such as Botox and Fillers are also an area of his expertise , where he has accumulated many years of experience, with more than 2500 combined procedures undertaken
After training with two of the best Hair Restoration Surgeons in the world (in Beverly Hills and Minneapolis), Dr Diaz is performing the same procedures in the U.K. with excellent results."
You could contact him and ask for examples of his work.
