A dermatologist is a medical practitioner who focuses on the treatment of conditions affecting for the most part the skin. Some of these conditions take account of, but are not restricted to, acne, eczema, and skin tumors. Dermatologists that graduate from medicinal schools outside of the US are requisite by law to get hold of a foreign graduate certificate earlier than they are allowed to practice dermatology. Just akin to other therapeutic doctors, dermatologists have been qualified and have completed as a minimum one year in a residency program intended for clinical training in internal medicine. Dermatologists are well thought-out medical specialists, seeing that they are fully trained therapeutic doctors who have undergone dedicated training in matters as regards skin conditions.
