How to book
Booking a Long Island dermatologist
Open a practice above and use its Call, Website or Book button. Each practice books its own appointments, and we never ask for your details or pass them on.
Medical concern? For a skin check, a changing mole, a rash or anything that is bleeding or not healing, contact the practice directly and say what you have noticed. Some insurance plans need a referral from your primary care doctor first, so check your plan before you book.
Cosmetic treatment? Botox, fillers, lasers and peels are paid out of pocket and need no referral. Ask who performs the treatment and how often they do it. You can also compare Long Island med spas.

FAQ
Dermatologists in Long Island, answered
How many dermatology practices are listed in Long Island?
We list 17 dermatology practices in Long Island, New York, each with a public Google rating and at least 25 reviews. MDCS Dermatology: Medical Dermatology and Cosmetic Surgery currently holds the highest rating-weighted score. The order is editorial and cannot be bought.
Do I need a referral or insurance approval to see a dermatologist in Long Island?
It depends on your plan. Many PPO plans let you book a dermatologist directly, while HMO and some marketplace plans need a referral from your primary care doctor first. Cosmetic visits (Botox, fillers, lasers, peels) are paid out of pocket and need no referral. Call the practice with your insurance card before you book.
Which Long Island dermatologists offer cosmetic treatments?
8 of the 17 practices here name three or more cosmetic treatments on their own websites. The most widely offered are Botox (9), Laser Hair Removal (8), Dermal Fillers (8). Each treatment links to local cost ranges and the Long Island clinics that offer it.
Should I see a dermatologist or a med spa for Botox or fillers?
Both can be a good choice. A dermatology practice has a physician who diagnoses skin conditions, which matters if you have a medical concern alongside a cosmetic one. A med spa is often easier to book and focused on cosmetic work, usually under a supervising physician. Ask either one who will actually perform your treatment and how often they do it.
Can I book a skin check or ask about a mole through ClinicCompass?
No. For a skin check, a changing mole, a rash or any other medical concern, contact the practice directly; we do not collect medical information. A spot that is changing, bleeding or not healing should be seen promptly and should never wait behind a cosmetic appointment.
