Dermatologists — FAQ

Dermatologists treat conditions affecting the skin, hair, and nails. Common conditions include acne, eczema, psoriasis, rosacea, seborrheic dermatitis, skin cancer, warts, moles, alopecia, and nail fungus. Cosmetic dermatologists also perform aesthetic procedures like Botox, fillers, and laser treatments.

The American Academy of Dermatology recommends annual skin exams for adults, especially those with fair skin, a history of sunburns, multiple moles, a family or personal history of skin cancer, or prolonged UV exposure. High-risk individuals may need more frequent screenings.

General (medical) dermatologists diagnose and treat skin diseases. Cosmetic dermatologists focus on aesthetic procedures to improve skin appearance. Many dermatologists practice both. For medical concerns like skin cancer or chronic skin conditions, choose a board-certified MD or DO with FAAD designation.

Follow the ABCDE rule: Asymmetry, Border irregularity, Color variation, Diameter larger than 6mm, and Evolution (any changes). If a mole displays any of these features, schedule an appointment with a dermatologist promptly. Early detection of melanoma dramatically improves outcomes.

Medical dermatology visits are typically covered by health insurance when medically necessary (treating acne, eczema, skin cancer, etc.). Cosmetic procedures (Botox, fillers, laser resurfacing for aesthetics) are generally not covered. Verify your coverage and any referral requirements with your insurer.

Dermatologists treat acne with topical medications (retinoids, antibiotics, benzoyl peroxide), oral medications (antibiotics, isotretinoin/Accutane for severe cases), hormonal therapy for women, chemical peels, and light/laser therapy. Treatment is tailored to acne type and severity.

A skin biopsy removes a small sample of skin tissue for laboratory analysis to diagnose or confirm a skin condition. It is a minor in-office procedure performed under local anesthesia. Types include shave biopsy, punch biopsy, and excisional biopsy, chosen based on the lesion being evaluated.

Mohs micrographic surgery is a precise surgical technique for treating skin cancers (primarily basal cell and squamous cell carcinoma) on the face, scalp, and neck. The surgeon removes thin layers of tissue and examines them under a microscope until no cancer cells remain, achieving high cure rates while preserving healthy tissue.

Common cosmetic procedures include Botox and Dysport (neuromodulators for wrinkles), dermal fillers (hyaluronic acid for volume), chemical peels, laser resurfacing, IPL (intense pulsed light) for pigmentation and redness, microneedling, and body contouring. Always consult a board-certified dermatologist or plastic surgeon for these treatments.

Arrive with clean skin free of makeup or nail polish (for nail concerns). Bring a list of current medications and supplements. Document any skin changes with photos before the visit. Have your health insurance card and referral (if required). Be prepared to describe when you first noticed the condition and any factors that worsen or improve it.
