A full-body skin exam is one of the most common and least intimidating things a dermatologist does — but if you have never had one, not knowing what happens can make it feel bigger than it is. This guide walks through the visit step by step, from checking in to the follow-up, so you know what to expect, what to wear, and how to make the appointment as useful as possible.
The short version
A skin check is a visual head-to-toe exam of your skin, looking for anything unusual or changing.
It is usually quick — often 15 to 30 minutes — and generally painless.
You will typically undress to your underwear and wear a gown.
The dermatologist may use a small handheld magnifier to look closely at spots.
If something needs a closer look, they may suggest a biopsy, which is a separate quick procedure.
Before the visit
A little preparation makes the exam smoother. Remove nail polish so nails can be examined, skip heavy makeup, and wear your hair loose so the scalp is easy to check. Make a note of any spots you are worried about so you can point them out. If you have photos of a mole that has changed over time, bring them.
Checking in and the conversation
Most visits start with a short conversation. The dermatologist or a staff member may ask about your history — past skin problems, sun exposure, any family history of skin cancer — and about any specific concerns you have today. This is the moment to mention anything that has been on your mind, so raise it early rather than at the end.
The exam itself
You will usually change into a gown. The dermatologist then examines your skin systematically, often from the scalp down: face, neck, torso, arms, hands, legs, feet, and the areas that are easy to overlook, such as between the toes and behind the ears. They are looking for anything new, changing, or unusual in color, shape, or texture.
The handheld magnifier
To look closely at a particular spot, a dermatologist often uses a dermatoscope — a small handheld device with a light and magnifier. It touches the skin gently and is completely painless. It simply lets them see detail that is invisible to the naked eye.

If something needs a closer look
If the dermatologist sees a spot that warrants further evaluation, they may recommend a biopsy — taking a small sample of skin to examine under a microscope. This is usually done right then, with local anesthetic to numb the area, and takes only a few minutes. It does not mean anything is wrong; it is simply how a definitive answer is reached. Results typically come back within a couple of weeks.
Pro tip — point out your worries first
Do not assume the dermatologist will automatically land on the exact spot worrying you. At the start of the exam, say clearly, “This one on my shoulder is what I am most concerned about.” It focuses their attention where you want it.
After the exam
At the end, the dermatologist will summarize what they saw, note anything to keep an eye on, and recommend when you should return. If everything looked fine, you will simply be told to watch for changes and given a suggested interval for your next check. If a biopsy was taken, the office will explain how and when you will get results.
Making it a habit
For people with risk factors — a lot of sun exposure over the years, many moles, fair skin, or a family history of skin cancer — regular skin checks can be a sensible routine. How often is a conversation to have with your dermatologist, because it depends on your individual risk.

The exam itself is visual and painless. If the dermatologist recommends a biopsy, the area is numbed with local anesthetic first, so you feel a brief pinch and then pressure rather than pain.
Do I have to fully undress?
For a full-body exam you usually undress to your underwear and wear a gown, so the dermatologist can examine your skin thoroughly. You can always speak up about comfort, and a chaperone can be requested.
How long do biopsy results take?
It varies, but results commonly come back within a couple of weeks. The office will tell you how they will contact you and roughly when to expect it.
How often should I get a skin check?
There is no single rule — it depends on your risk factors and history. Some people benefit from an annual check, others less often. Ask your dermatologist what interval fits your situation.
