What does a dermatologist do?

A dermatologist is a medical doctor who examines the skin, hair, and nails to diagnose disease and recommend treatment. Day-to-day work can include patient history-taking, visual and tactile examination of lesions, ordering diagnostic tests, and creating evidence-based treatment plans. Dermatology practice spans general medical care, cosmetic procedures, and preventive guidance. Professionals often counsel patients on safety, medication use, and when referral to another specialist is appropriate to manage systemic disease with dermatologic manifestations.

Clinical and diagnostic responsibilities

Diagnostic skills are central to dermatology: careful examination, dermoscopy, skin biopsies, and laboratory tests inform accurate diagnosis. Dermatologists interpret clinical and histological data to distinguish benign conditions from malignant disease and to direct appropriate medical or surgical treatment. Use of digital imaging and teledermatology can support diagnostic workflows in clinics and hospitals, while maintaining standards for patient privacy and clinical safety. Clear documentation of diagnostic reasoning supports continuity of care and collaborative management with other healthcare professionals.

Work environments: hospital, clinic, and healthcare settings

Dermatology roles exist across hospitals, outpatient clinics, private practice, and academic healthcare centers. Hospital-based dermatologists frequently consult on inpatient cases, aid oncology and transplant teams, and manage acute or complex skin disease. Clinic-based practice emphasizes outpatient examinations, routine follow-ups, and elective procedures. Each setting imposes different administrative, safety, and professional expectations—ranging from infection control in surgical suites to scheduling and documentation practices in community clinics. Local regulations and institutional policies shape scope of practice in your area.

Common skin diseases and treatment approaches

Dermatology professionals treat conditions such as eczema, acne, psoriasis, fungal infections, and precancerous or cancerous lesions. Treatments include topical and systemic medicines, phototherapy, minor surgical procedures, and procedural cosmetic care. Clinical decisions factor in disease severity, coexisting medical conditions, and patient preferences. Cosmetic dermatology may overlap medical care when skin health is affected, requiring diagnostic confirmation before elective treatments. Patient education on skin safety, sun protection, and medication adherence is a routine component of effective management.

Professional training, clinical safety, and patient examination

Typical training pathways require medical school followed by dermatology residency and, optionally, fellowship subspecialization. Competence involves mastery of clinical examination, procedural techniques, diagnostic interpretation, and patient communication. Clinical safety practices include appropriate use of local anesthesia, sterile technique for minor procedures, and risk assessment before systemic therapies. Informed consent and documentation of clinical findings and treatment plans are essential. Continuous professional development and adherence to evidence-based guidelines support high standards of clinical care and patient safety.

Practice considerations in regions like Japan and cosmetic care

Regional differences, such as regulations in Japan or other countries, influence licensing, clinical privileges, and accepted treatment protocols. Dermatology professionals practicing in different jurisdictions must be familiar with local medical regulations, hospital credentialing, and professional standards. Cosmetic dermatology services—ranging from injectables to laser procedures—require clinicians to balance aesthetic goals with medical safety, appropriate diagnostic evaluation, and clear communication about realistic outcomes and risks. Collaborative practice with dermatopathology or other specialties can improve diagnostic accuracy and patient care.

Conclusion

Dermatologist roles integrate diagnostic dermatology, medical and procedural treatments, and patient-focused care across hospitals, clinics, and diverse healthcare environments.
