How an Online Dermatology Visit Actually Works

The Two Formats: Live Video and Store-and-Forward

Teledermatology comes in two structurally different forms, and which one a platform uses changes what the visit can accomplish. A live-interactive visit is a real-time video call where the clinician can ask follow-up questions, request a different angle or better lighting on the spot, and examine movement or texture that a still photo can't capture. A store-and-forward visit is asynchronous: a patient uploads photos and answers a structured history, and a clinician reviews the file and responds later, sometimes within hours.

Both formats are expected to meet published teledermatology practice standards covering image quality, platform security, and how the visit is documented 1Ref 1American Academy of Dermatology (2024).Teledermatology Standards.The two-format structure of teledermatology (live-interactive and store-and-forward) and the image-quality and platform-security standards both are expected to meet.. Store-and-forward tends to be faster to book and often cheaper, since no clinician time is scheduled in real time; live video allows more back-and-forth when a case is ambiguous.

Before the Visit: Intake and Photos

Most platforms start with a structured intake form asking how long the issue has been present, what's been tried already, relevant medical history, and current medications — the same information a dermatologist would ask in person, just typed instead of spoken. Photo instructions typically call for natural light, a neutral background, and at least one close-up plus one wider shot showing the affected area in context, since a single tight close-up strips out information a clinician would otherwise get from seeing the surrounding skin.

For anything on the scalp, in skin folds, or in a spot that's hard to photograph alone, some platforms allow a second person to help capture the image, or default to a live-video format instead.

During the Visit

In a live-video visit, the appointment runs much like an in-person one condensed into a shorter window: the clinician reviews the history, asks about the area of concern, may ask to see it from a different angle or under different lighting, and discusses a plan out loud. In a store-and-forward visit, there is no real-time exchange — the clinician works only from what was submitted, which means an incomplete photo set or a vague history description directly limits what can be assessed, with no chance to ask a follow-up question mid-review.

Either way, the visit ends with a written assessment and plan, sent through the platform's messaging system or portal rather than read aloud.

What Happens After: Prescriptions and Follow-Up

When a prescription is appropriate, it's typically sent electronically to a pharmacy of the patient's choosing, the same way an in-person prescription would be. Follow-up is usually built into the same platform — a message thread to report how a treatment is working, sometimes with new photos, rather than a fully separate visit, though some plans require another paid visit for anything beyond a quick check-in.

What online visits are less suited to prescribing is anything requiring in-person monitoring — a medication with a mandated safety program, or one that needs a physical exam or lab work before it can be started safely, tends to route back to an in-person dermatologist rather than being handled entirely online.

Why Teledermatology Exists as an Option at All

Part of the reason online visits exist as a mainstream option, rather than a niche convenience, is supply: dermatologists are heavily concentrated in metropolitan areas, and large stretches of the country have very few or none within a reasonable drive 2Ref 2Feng H, Berk-Krauss J, Feng PW, Stein JA (2018).Comparison of Dermatologist Density Between Urban and Rural Counties in the United States.The geographic concentration of dermatologists in metropolitan areas as the access rationale for teledermatology's growth in underserved regions.. For someone in that position, a store-and-forward or live-video visit can be the difference between being seen this week and waiting months for the nearest open in-person slot — which is also why rural telehealth reach and direct-to-consumer dermatology services have grown together rather than as separate trends.

Where Photo-Based Assessment Reaches Its Limit

Most rashes, acne, and common inflammatory conditions photograph well enough for a confident remote assessment. Pigmented lesions are the clear exception. Evaluating a mole for the features that matter — asymmetry, an irregular border, color variegation, a diameter over roughly 6 millimeters, and whether it has been evolving over time — depends on comparing it against its own history and, often, close in-person inspection with magnification that a photo alone doesn't replace 3Ref 3Tsao H, Olazagasti JM, Cordoro KM, et al. (2015).Early detection of melanoma: reviewing the ABCDEs.The ABCDE criteria for evaluating a pigmented lesion, and why the 'evolving' criterion in particular depends on comparison over time that a single photo cannot provide.. A single image, no matter how well lit, can't show how a spot has changed since last year, and evolving is one of the five criteria that matters most.

Most teledermatology platforms are built around this limit rather than around it: many will decline to render a definitive assessment of a new or changing pigmented lesion by photo and will instead direct the patient to an in-person dermatologist for that specific concern, which is the appropriate response rather than a failure of the format.

What an Online Visit Typically Costs

Pricing and insurance handling for these visits is its own topic, since it depends heavily on whether the platform bills insurance or charges a flat cash fee, and whether the visit is a first consult or a follow-up. The mechanics above — format, intake, and what the plan sent afterward looks like — are the same regardless of how the visit is paid for.
