How to photograph a skin concern properly

A dermatologist assessing your skin remotely can only work with what the camera captured. A sharp, well-lit photo often carries enough detail to reach a confident answer. A dark, blurry one carries almost none — and the honest response to it is "I can't tell."

Here's what actually helps.

Light

Stand near a window during the day and let the light fall on the area. Never use the flash: it flattens texture, washes out redness, and hides exactly the surface detail that matters. Overhead lighting at night is the second-worst option — it casts hard shadows that mimic depth that isn't there.

Distance

Take two photos of the same spot:

• One from about 30 cm, showing the area and the skin around it
• One close-up, as near as your camera can focus while staying sharp

The wider shot gives context — how it sits on the body, whether there are others nearby. The close-up gives detail. Neither alone is enough.

Focus

Tap the screen directly on the spot before shooting. Phone cameras habitually focus on whatever is closest or most contrasty, which is often not the thing you care about. If the photo looks soft when you zoom in on your own screen, it will be useless on ours — take it again.

Scale

For a mole, a spot, or anything where size matters, put something familiar beside it: a coin, the tip of a pen, a ruler if you have one. Size and change in size are among the most important signals in dermatology, and a photo without a reference gives neither.

What not to do

Don't apply makeup, cream, or ointment before photographing. Don't use filters or "beauty" modes — many phones smooth skin by default, which erases texture that carries real information. And don't crop tightly before sending; send the full frame and let the doctor zoom.

Three minutes of care here saves a round of back-and-forth, and often makes the difference between a clear answer and a request to come in person.
