Dermatology or dermatology is a medical specialty that deals with the diagnosis, treatment and prevention of diseases of the skin, hair, nails and surrounding tissues. Dermatologists address a wide range of issues related to skin health and are specialists in this field. Here are the focal points and practice areas of dermatology:

Skin Diseases: Dermatologists diagnose and treat a variety of skin diseases. These include acne, eczema (atopic dermatitis), psoriasis, rosacea, vitiligo, lichen planus and skin cancer.

Skin Cancer Screening: Dermatologists screen for skin cancer to detect skin cancer types such as melanoma, basal cell carcinoma and squamous cell carcinoma early. Early detection can improve the chances of cure.

Skin Surgery: Dermatologists can surgically remove skin lesions. This can include cancerous or precancerous lesions, moles (nevi), warts and other skin growths.

Cosmetic Dermatology: Cosmetic dermatological procedures such as skin rejuvenation, wrinkle treatment, spot treatment, botox, fillers and laser treatments are also performed by dermatologists.

Hair and Nail Problems: Dermatologists treat hair and nail conditions such as hair loss, dandruff, ringworm (alopecia areata), nail fungus and nail bed problems.

Allergy Tests: Skin tests are performed to examine allergic reactions on the skin. This helps diagnose conditions such as allergic dermatitis and contact dermatitis.

Pediatric Dermatology: Pediatric dermatologists diagnose and treat skin problems in children.

Sun Damage and Photoprotection: Dermatologists recommend photoprotection to reduce the risk of sunburn, sunspots and skin cancer.
