Teledermatology lets you connect with a dermatologist remotely — by sending photos, by video, or a combination — rather than always going in person. It has made skin care more accessible for many people, but it is not right for every situation. This guide explains how it works, what it handles well, where it falls short, and how to give a remote dermatologist what they need to help you.
The short version
Teledermatology means evaluating skin concerns remotely, by photo or video.
It can be convenient for many common, visible concerns and follow-ups.
Good photos and clear history make a big difference to the outcome.
Some concerns still need an in-person exam or a procedure.
A remote dermatologist may refer you in if something needs a closer look.
The two main formats
Teledermatology generally works in one of two ways, and some services combine them.
Store-and-forward (photos)
You submit photos of the concern along with a description and history. A dermatologist reviews them on their own schedule and responds with an assessment or next steps. This format is convenient and does not require both parties to be available at the same time.
Live video
You have a real-time video visit with a dermatologist, similar to other telehealth appointments. This allows back-and-forth conversation and the ability to show the concern from different angles as the dermatologist directs.

What teledermatology handles well
Remote care can be a good fit for many common, visible concerns and for follow-up. It can be especially helpful when getting to an office is difficult, when you want an initial opinion on whether something needs in-person attention, or for checking in on a known condition and adjusting a plan. For a lot of everyday skin questions, it is a genuinely useful option.
Where it falls short
Teledermatology has real limits. A photo cannot always capture what a dermatologist would see and feel in person, subtle features can be missed, and anything that requires a procedure — a biopsy, a removal, or a treatment done in the office — cannot be done remotely. For a concerning or ambiguous spot, an in-person exam is often the safer route, and a good remote dermatologist will tell you when that is the case.
Pro tip — take better photos
Use good, even lighting, get close enough to show detail but keep the image in focus, and include one wider shot for context plus a close-up. A ruler or coin beside the spot gives scale. Clear photos are the single biggest thing you control in a store-and-forward visit.
How to get the most from a virtual visit
Preparation matters even more remotely than in person. Write a clear history: when the concern started, how it has changed, what makes it better or worse, and what you have already tried. Take the best photos you can. Be specific about your main question. The more complete the picture you provide, the more useful the dermatologist’s response can be.
When to choose in-person instead
Lean toward an in-person visit for anything that looks like it could be skin cancer, a spot that is changing or that worries you, a concern that needs a procedure, or a problem that a remote assessment could not resolve. Teledermatology is a valuable tool, but it complements in-person care rather than fully replacing it. If a remote dermatologist recommends you come in, take that seriously.
Prefer to be seen in person?
Browse and compare dermatologists near you on Dermatologists At Your Service.
For many common, visible concerns and follow-ups, it can be very useful. But it cannot replace an in-person exam for everything — some features are hard to capture remotely, and procedures require an office visit. The best choice depends on your specific concern.
Can a dermatologist diagnose from photos alone?
Sometimes, for clear and common concerns with good photos and history. In other cases, they may need an in-person exam to be confident, or to perform a test. A responsible dermatologist will tell you when photos are not enough.
Can I get a prescription through teledermatology?
In many cases a dermatologist can prescribe remotely when appropriate, depending on the service and local rules. Whether it is suitable depends on the concern and the dermatologist’s assessment.
What should I do if my remote dermatologist tells me to come in?
Take it seriously and book an in-person visit. A recommendation to be seen in person usually means something warrants a closer look or a procedure that cannot be done remotely.
