Patients may attend with rashes, itching, acne, pigment changes, hair loss, nail problems, infections or a new or changing skin lesion. A dermatologist evaluates the pattern, duration, triggers and medical history through detailed skin examination, supported when necessary by laboratory tests, dermoscopy or biopsy. Treatment can include topical or oral medicines, procedural care, preventive advice and referral to cosmetology for selected concerns. The aim is to identify the condition accurately, relieve symptoms and protect the long-term health and integrity of the skin.
