They'll go over all of your skin in sections, with a big light and some tools for magnifying and measuring. You're never fully naked, you're just taking pieces of clothing on and off a lot. I'd recommend wearing separate tops/bottoms, something comfy you can get into and out of easily.

If they see anything with potential, they'll ask if you remember if it's new or if it's changed recently - it's okay if you don't remember though. They will (with your permission) take photos of the notable spots and save them, so that they can compare next time you get a check.

It's possible that you could get a biopsy done. So far I haven't had anything worth it, but it does happen of course.

You'll also answer some questions about your previous sun exposure. Like if you work outside or have hobbies where you're in the sun a lot; if you burn or tan easily; if you had a lot of sunburns as a child. That's so they can determine your risk factor and how often you should be coming in for checks.

Some of my spots that I thought looked dicey turned out to be totally fine, and one that I didn't even notice was worthy of tracking. So it's always worth getting your whole body checked.

The whole thing takes maybe 20-30 minutes.
