What does a dermatologist cost?
What moves the price
- Medical visits (skin checks, acne, biopsies) usually run through insurance; cosmetic work (Botox, fillers, most lasers) is always out of pocket.
- Injectables are priced per unit or per syringe, and the total depends on how many areas you treat.
- Laser treatments are sold as packages of sessions; the per-session price drops but the commitment grows.
- Who performs the treatment: physician time costs more than a nurse injector under supervision.
Ask each company to confirm these in writing before work starts. One free request above reaches up to three of them at once.
What dermatologists in Old Westbury, NY actually do
Practices differ more than their websites suggest. Some are medical first and bill insurance, some are cosmetic and do not, and not all of them perform Mohs surgery or own the device you came in for. Here is what each treatment involves, including the downtime most sites are vague about.
The reason a dermatologist is a physician. Usually billed to medical insurance, unlike everything below.
Full-body skin exam
A head-to-toe check for anything that has changed, which is how skin cancer is caught while it is still small.
When you call to book, confirm that the practice accepts your insurance and ask how they code a preventive skin exam versus a problem-focused visit, since that affects what you owe. Bring a list of any spots you want the doctor to look at specifically so nothing gets missed during the appointment.
Ask about. Whether the physician performs the exam themselves, and how quickly they can see you if something needs a closer look.
Worth knowing. Usually billed to medical insurance rather than treated as cosmetic, so confirm coverage when you book.
Biopsy of a suspicious spot
Removing a small sample so a pathologist can say what something actually is.
Ask the practice whether they send biopsy samples to an outside pathology lab or process them closer in house, because that directly affects how long you wait for results. Results typically come back in one to two weeks. Also ask whether the doctor can take a biopsy on the same visit as your initial exam, which saves you a return trip.
Ask about. Whether pathology is read in house or sent out, since that is what decides how long you wait for an answer.
Worth knowing. A dermatologist who takes a biopsy on the same visit saves you a second appointment and a second wait.
Mohs surgery
Removing skin cancer layer by layer, checking each one under a microscope before going further, which spares the most healthy tissue.
Not every dermatology practice in the area offers Mohs on site, so ask directly before you book. Many refer it out, which is completely normal, but knowing that upfront helps you plan. Also ask about the repair after removal, since closing the wound is part of the same procedure and the approach varies by location on the body.
Ask about. Whether the surgeon is fellowship trained in Mohs, and who performs the repair afterwards.
Worth knowing. Not every dermatology practice offers Mohs. Many refer it out, which is normal and worth knowing before you book.
General medical dermatology
The everyday medical side of the specialty, from prescriptions to ongoing management, as opposed to cosmetic work.
Before booking, confirm that the practice takes your insurance for medical visits, because some offices handle cosmetic work only and do not bill insurance at all. Ask whether the physician who sees you will also manage ongoing prescriptions or whether follow-up visits go to a different provider within the practice.
Ask about. Whether the practice takes your insurance for medical visits, since some cosmetic-focused clinics do not.
Worth knowing. A practice can be excellent at cosmetic work and not take medical insurance at all. They are different businesses under one roof.
Botox, Dysport and Xeomin
Softening lines that come from movement, most often forehead, frown and crow's feet.
Ask who will actually perform the injection, whether that is the physician or a supervised injector, and whether a doctor will be on site during your appointment. Also ask for the price per unit and an estimate of how many units your areas typically require, so you know the full cost before you sit down.
Ask about. Who injects, and if it is not the physician, who supervises and whether they are on site.
Worth knowing. Results build over about two weeks, so judging it the next day is judging it too early.
Juvederm, Restylane and other HA fillers
Adding volume where it has been lost, or shaping lips, cheeks and the area under the eyes.
Ask to see before-and-after photos of actual patients treated at that practice, ideally with a skin type similar to yours, rather than manufacturer images. Confirm who performs the injection and what the protocol is if you have a concern after you leave, since the ability to dissolve hyaluronic acid filler quickly in a complication is time-sensitive.
Ask about. Which product they are using and why, since the filler chosen for cheeks is not the one for tear troughs.
Worth knowing. Hyaluronic acid fillers can be dissolved if you dislike the result, which is a real advantage over permanent products.
Sculptra and collagen stimulators
Building volume gradually by prompting your own collagen, rather than filling immediately.
Go in knowing that visible change builds over months rather than days, and ask the practice how many sessions your plan includes and what the total cost looks like across all of them. Also ask about the daily massage routine required in the first week after each session, since skipping it affects how the product settles.
Ask about. How many sessions are planned and what the total cost is, since this is priced as a course rather than a single visit.
Worth knowing. It works slowly on purpose. If you want to see a change tomorrow, this is the wrong product.
Kybella
Reducing fullness under the chin by breaking down fat in that specific area.
Ask the practice to walk you through the swelling timeline honestly, because significant swelling for a week or more is a normal part of the process and not a sign something went wrong. Find out how many sessions your plan is likely to involve and what the total cost across those sessions will be before you commit.
Ask about. How many sessions they expect and what the swelling looks like in week one.
Worth knowing. The downtime is the honest objection here, and any clinic that describes it as a lunchtime treatment is glossing over it.
CO2 ablative resurfacing
The most aggressive resurfacing option, used for deeper lines, texture and sun damage.
Ask the practice for a detailed written aftercare plan before your appointment, not after, because strict sun avoidance following this treatment is the step that most often goes wrong. Also confirm who will operate the device and what their experience level is with this specific system, since operator training matters more than the brand of machine.
Ask about. Who operates the laser, whether the physician is present, and what the aftercare actually requires.
Worth knowing. Strict sun avoidance afterwards is not optional, and it is what most often goes wrong with this treatment.
Fraxel and fractional non-ablative lasers
Improving texture, tone and sun damage with far less downtime than ablative resurfacing.
Because Old Westbury summers bring real sun exposure, fall is the most practical time to start a course of fractional laser sessions, when lower UV levels make the post-treatment avoidance period easier to manage. Ask the practice how to handle aftercare through the dry winter months that follow, since dry air can affect how comfortable healing feels.
Ask about. Which specific device they use, since Fraxel is a brand and the settings matter more than the name.
Worth knowing. The middle option: more than IPL, much less than CO2, and the one most people are actually looking for.
IPL and photofacials
Evening out brown spots and redness from sun exposure, across the face, chest and hands.
IPL works well on the kind of seasonal sun damage that builds up over Old Westbury summers, but the treatment needs sun avoidance afterward, making fall the better window to start a course rather than mid-summer. Before booking, tell the practice your skin tone, because IPL carries real risk on darker skin types and a good office raises that question before you do.
Ask about. Whether IPL is appropriate for your skin tone, because it is not safe on all of them.
Worth knowing. IPL carries real risk on darker skin types. A practice that asks about your skin type before booking is doing it right.
Nd:YAG and vascular lasers
Treating visible vessels, redness and some pigment, and used for laser hair removal.
Ask the practice which specific device they use and whether it has been chosen with your skin tone in mind, since Nd:YAG is often selected precisely because it is better suited to a wider range of tones than other options. Find out how many sessions your plan typically involves and how far apart they are spaced.
Ask about. Whether the operator is trained for your skin type, since these devices are where burns happen when they are not.
Worth knowing. Safer across darker skin tones than IPL, which is often the reason it is chosen.
Picosecond lasers for tattoo removal
Breaking up tattoo ink, and also used for stubborn pigment.
Ask the practice to give you an honest session estimate based on your tattoo's colors, age and depth, since all three affect how many treatments it takes. Also ask what the per-session cost is and what happens if progress stalls, because no practice can promise complete removal regardless of how many sessions you do.
Ask about. How many sessions they estimate for your ink colours, because greens and light blues are the difficult ones.
Worth knowing. Nobody can promise complete removal. Colour, depth and age of the tattoo all decide the outcome.
Microneedling with radiofrequency
Tightening and improving texture using needles plus heat, on a wider range of skin tones than most lasers.
Ask who operates the device at that specific practice and what their experience is with the system being used. Confirm how many sessions your plan includes and ask to see the total cost across all three, since results build gradually over months and the commitment is the full course rather than a single visit.
Ask about. Whether it is done by the physician or a delegated provider, and what depth settings they use.
Worth knowing. One of the few resurfacing options generally considered appropriate across all skin types.
The questions worth asking, and the two you can check yourself
Who is legally allowed to inject or operate a laser differs by state and changes over time, so the honest thing a directory can offer is the questions rather than the rules. A good practice answers all six without hesitating.
Who will actually perform the treatment?
At many practices a nurse, physician assistant or aesthetician performs injectables and laser work under a physician's delegation. That can be perfectly good care, but you should know before you are in the chair rather than after.
Will a physician be on site while it is done?
On-site supervision requirements differ by state and by procedure. Asking the question tells you both the answer and how comfortable the practice is being asked.
Is the physician board certified in dermatology?
Any licensed physician may legally call themselves a skin or cosmetic specialist. Board certification through the American Board of Dermatology is the specific credential, and it can be verified for free.
Check board certification (ABMS Certification Matters)Is the license active, with no board actions?
Every physician is licensed by a state medical board, and the boards' national lookup shows the license and any actions taken against it. It is free and takes a minute, and it is the one check a practice cannot answer for you.
Look up a doctor's license (DocInfo)What happens if something goes wrong, and who handles it?
Filler occlusions and laser burns are rare but real, and they are time-critical. The answer should be a named physician and a same-day route to them, not a voicemail box.
Is this device appropriate for my skin type?
Several light-based devices carry real risk of burns or pigment change on darker skin. A practice that raises this before you do is one that has thought about it.
What is the total cost, including the sessions after this one?
Injectables are quoted per unit and devices are often sold as a course. The number that matters is the whole plan, not the first appointment.
General information about what these treatments involve, not medical advice, and not a statement of what any state permits. Verify board certification with the American Board of Dermatology and check scope-of-practice rules with your state medical board.
When to book a dermatologist in Old Westbury
Spring
May is Skin Cancer Awareness Month and screening demand spikes; book annual skin checks ahead of it.
Summer
Most laser and peel treatments need sun avoidance afterward, so summer is consult season, not treatment season.
Fall
The start of laser and resurfacing season: less sun exposure means safer healing, and offices book up fast.
Winter
Peak cosmetic season, plus December FSA dollars expiring; injectable appointments before holidays fill weeks out.

How long does Mohs surgery take?
Mohs surgery removes skin cancer one thin layer at a time, with the surgeon examining each layer under a microscope before deciding whether to go further. That process spares as much healthy tissue as possible. Plan on a half day in the office, sometimes longer, followed by stitches and a healing period of roughly two to four weeks depending on where on the body the site is.
Is cosmetic dermatology covered by insurance?
Medical visits like skin checks, acne management and biopsies are usually billed to medical insurance. Cosmetic treatments are always out of pocket. Injectables are priced per unit or per syringe, so ask for the full total before agreeing to anything. Laser and device treatments are typically sold as a course of sessions, so the number that matters is the whole plan, not just the first appointment.
What happens at a skin check?
A full-body skin exam is a head-to-toe look at everything on your skin, which is how anything that has changed gets caught early. The visit typically runs 15 to 30 minutes with no downtime. How often you should go is not a one-size answer, the U.S. Preventive Services Task Force found the evidence insufficient to recommend routine screening for adults without symptoms, so let the dermatologist set a schedule based on your personal risk.
How do I check if a dermatologist is board certified?
Board certification through the American Board of Dermatology is the specific credential to look for, and it can be verified free at certificationmatters.org, which is linked on this page. A medical license alone does not make someone a dermatologist. You can also check whether a physician's license is active and free of board actions through a national lookup that is also linked here, and it takes about a minute.
How much downtime is there after laser resurfacing?
Downtime depends heavily on which device is used. CO2 ablative resurfacing means raw skin for several days and visible redness for weeks. Fractional non-ablative lasers like Fraxel leave a sandpaper texture for three to seven days. IPL is the lightest, with a day or two of flushing. Before booking any device treatment, ask the practice whether it is appropriate for your specific skin tone, since several options carry real risk on darker skin.
