A dermatologist is the medical expert you should consult if you have any significant problem with your skin. Dermatology is the science that is concerned with the diagnosis and treatment of diseases of the skin, hair and nails.

Dermatologists perform skin surgery in many situations:

• To prevent or provide early control of disease, eg remove skin cancer.

• To improve the skin's appearance by removing growths, discolourations, or damage caused by ageing, sunlight or disease.

• To establish a definite diagnosis (biopsy).
