A skin check by a dermatologist is a head-to-toe visual examination of your entire skin surface, designed to spot skin cancer and other abnormalities early. The exam itself typically takes less than three minutes of actual inspection time, though your full appointment will be longer to allow for discussion and any follow-up steps. It’s one of the simplest medical exams you can get, but knowing what to expect makes it easier to walk in prepared.
What Happens During the Exam
Your dermatologist follows a systematic path across your body so nothing gets missed. You’ll change into a medical gown, and the exam typically moves in this order: scalp first (your dermatologist will part your hair to see the full surface), then face, ears including the ear canal, neck, upper body, arms, hands, trunk (chest, abdomen, back, and sides), legs, feet, and finally nails and the inside of your mouth.
Some areas people don’t expect to be checked include between the fingers and toes, under the nails, the soles of the feet, and the skin beneath the breasts. Your dermatologist may also discuss examining the genital area, buttocks, and perianal region, since skin cancer can develop in places that never see the sun. If another provider already checks those areas regularly, that’s worth mentioning.
Throughout the exam, your dermatologist is looking for asymmetry, color changes, unusual textures, and lesions that stand out from your normal skin pattern. They’re trained to recognize subtle differences that you’d likely never notice on your own, particularly on your scalp, back, and other hard-to-see areas.
The Dermatoscope: Seeing Below the Surface
If your dermatologist spots something worth a closer look, they’ll likely pull out a dermatoscope, a handheld magnifying device that reveals colors, structures, and patterns beneath the skin’s surface that are invisible to the naked eye. It provides roughly 10x magnification and works by changing how light interacts with your skin, letting the dermatologist see deeper pigment patterns and tiny blood vessel structures.
This tool is important for two reasons. It helps identify early melanomas that don’t yet show the classic warning signs you might recognize on your own. And it prevents unnecessary biopsies by allowing the dermatologist to confirm that a suspicious-looking spot is actually harmless. The exam with a dermatoscope is completely painless and noninvasive.
How to Prepare
A few simple steps make the exam more effective:
- Skip the makeup. Many skin cancers on the face, particularly basal and squamous cell carcinomas, are subtle enough that foundation or concealer can hide them. Sunscreen alone is fine.
- Remove nail polish and artificial nails. Skin cancer can develop under your nail beds, and polish masks the discoloration that signals a problem. If you can’t remove them beforehand, your dermatologist will ask whether you’ve noticed any changes underneath.
- Go easy on hair products. Heavy hairspray, dry shampoo, and scalp powders for thinning hair all make it harder to examine your scalp thoroughly. Expect your hairstyle to get disrupted during the exam regardless.
It also helps to make a mental note of any spots that have changed recently, are new, or concern you for any reason. Pointing these out at the start of your appointment gives your dermatologist specific areas to pay extra attention to.
What Happens If Something Looks Suspicious
If your dermatologist finds a spot that needs further evaluation, the next step is usually a biopsy, a quick in-office procedure where a small sample of skin is removed and sent to a lab. You’ll receive a numbing injection at the site first, so the procedure itself is painless.
There are three common types. A shave biopsy is the most frequently used: a razor removes a thin sample from the top layers of skin, and no stitches are needed. A punch biopsy uses a small circular blade (about the size of a pencil eraser) to take a deeper sample, and may require a stitch or two. An excisional biopsy uses a scalpel to remove the entire suspicious area and is typically reserved for spots that look like they could be melanoma, since removing all the tissue at once is preferred.
For basal cell and squamous cell carcinomas, the two most common skin cancers, the biopsy itself often removes the entire problem and no further treatment is needed. Melanoma requires additional testing to determine whether the cancer has spread, followed by a tailored treatment plan.
Results typically come back within one to two weeks. Many biopsied spots turn out to be benign.
Who Should Get a Skin Check
Here’s where things get a bit nuanced. No major U.S. medical organization currently has a blanket recommendation for routine skin cancer screening in people without symptoms. The U.S. Preventive Services Task Force rates the evidence as “insufficient” to recommend for or against it in the general population. That doesn’t mean skin checks aren’t valuable. It means large-scale studies haven’t yet proven a mortality benefit for screening everyone.
In practice, dermatologists widely recommend regular skin checks for people with elevated risk: a personal or family history of skin cancer, a history of severe sunburns or tanning bed use, a large number of moles, fair skin that burns easily, or a weakened immune system. If you have any of these risk factors, a yearly exam is a reasonable baseline. Your dermatologist may suggest more or less frequent visits depending on what they find and your individual risk profile.
Insurance and Cost Considerations
Because there’s no universal screening recommendation from the USPSTF, insurers aren’t required to cover skin checks as preventive care under the Affordable Care Act. Whether your visit is covered depends on your specific plan and, importantly, on how the visit is coded. If you go in because you noticed a changing mole or a new spot, that’s a diagnostic visit and is more likely to be covered. A purely screening visit with no symptoms may come with an out-of-pocket cost. Calling your insurance beforehand and asking about coverage for both “screening” and “diagnostic” dermatology visits will save you from surprises. Many dermatology offices can also clarify this before your appointment.
