Dermatologists are trained to treat patients of all ages, from newborns to the elderly. This includes the diagnosis, treatment and prevention of problems of the skin, hair and nails. Conditions common among children are moles and birthmarks, dermatitis, acne, warts, vitiligo, insect bites and birth defects. In adults we treat a range of conditions such as cancers and pre-cancers, rosacea, psoriasis and shingles. We also treat eczema, allergies and other disorders that occur in all age groups, and carefully examine moles or other growths to determine whether they are or may become cancerous.
