Dermatology is one of the more difficult specialties to access quickly. The supply of dermatologists has not kept pace with patient demand, and in many regions, particularly rural ones, a new patient appointment can take weeks or months to secure. Teledermatology, the practice of delivering skin care remotely through digital tools, has developed as a direct response to that gap. Dermatology with telehealth allows a patient to submit photographs or connect over live video with a licensed provider, often receiving an assessment far sooner than a standard office visit would allow.
This article outlines how teledermatology functions in practice, which conditions it tends to handle well, where its limitations lie, and what patients should consider when using it.

Two Established Models of Care
Teledermatology generally operates through one of two established models, and many practices use a combination of both depending on the case.
The first is the store and forward model, sometimes called asynchronous teledermatology. A patient, or in some cases a referring primary care provider, photographs the affected area and submits a written history covering symptoms, duration, and any treatments already attempted. This information is transmitted through a secure platform to a dermatologist, who reviews it independently of the patient’s schedule. Research on this model, including a comparative review published in the Journal of Medical Internet Research, notes that store and forward consultations tend to reduce wait times because they do not require both parties to be available at the same moment. Response times through this model commonly fall within a 24 to 72 hour window, though this varies by provider.
The second model is live interactive video, also called synchronous teledermatology. The patient and dermatologist connect through a secure video call, comparable in format to standard video conferencing software but built to meet health privacy standards. This format supports real time conversation and allows the dermatologist to direct the visit, asking the patient to adjust lighting, change the camera angle, or point out specific areas of concern.
A third approach, often called the hybrid model, combines elements of both. A patient might submit photographs in advance and then join a live call for discussion, or a store and forward case might be escalated to video if the dermatologist needs more information. Studies comparing these approaches generally find that diagnostic accuracy is comparable between the two primary models, though patient and physician preferences tend to differ depending on the situation and the complexity of the case. The choice between formats is often made by the platform itself, based on the type of concern reported during intake, rather than left entirely to patient preference.
The Structure of a Typical Virtual Visit
Most virtual dermatology visits begin with an intake form. Patients are asked to describe the concern, note when it started, list any treatments already tried, and provide relevant medical history, including allergies and current medications. The accuracy of this information matters, since the reviewing provider is working from a combination of visual data and reported history instead of a full physical exam.
For visits that rely on photography, image quality has a meaningful effect on the outcome. Platforms typically provide guidance on lighting and framing, since blurry or poorly lit images are a common obstacle to an accurate remote assessment. Natural daylight tends to produce clearer results than artificial indoor lighting, and providers generally ask for a combination of close up images that show texture or borders and wider shots that show the surrounding skin for context.
Once the case is submitted, a licensed provider reviews it. In many services, this role is filled by board certified virtual dermatologists who specialize in evaluating remote submissions against established clinical patterns. They weigh the visual evidence alongside the reported history and determine whether the case can be managed remotely or should be referred for an in-person exam. When a diagnosis can be made, the provider typically returns a written summary of the likely condition along with a management plan, which may include a prescription sent electronically to the patient’s pharmacy, over the counter recommendations, or instructions for monitoring the condition over time.
Live video visits follow a similar arc but in real time. The dermatologist asks questions directly, may request a closer look at a specific area, and can typically offer an assessment and next steps before the call ends. This format tends to work best for cases where the history is complicated or where a back and forth conversation would clarify something a photograph alone could not
Conditions Commonly Managed Through Telehealth
A substantial share of dermatology cases have visual patterns that an experienced provider can recognize from clear images or video, particularly when paired with an adequate patient history. Conditions frequently managed this way include acne, eczema, psoriasis, rosacea, cold sores, contact dermatitis, hives, and minor rashes or insect bites.
Follow up care is another area where telehealth is well suited. A patient already diagnosed in person, who needs a check in on treatment progress or a prescription adjustment, can often handle that through a brief virtual visit in place of a full office appointment. Chronic conditions such as psoriasis and eczema, which require ongoing management over months or years, tend to benefit from this more frequent, lower friction contact with a provider.
Teledermatology also plays a growing role in triaging suspicious moles or lesions. Photographs, expecially when taken with a dermatoscope attachment, can help a dermatologist judge whether a spot is likely benign or warrants urgent in-person evaluation. A 2024 study on patient initiated teledermoscopy found that adding dermatoscope images to a remote review reduced the rate of conversion to in-person visits by more than half compared with standard clinical photographs alone, which points to a practical way to cut down on unnecessary office visits without delaying referral for lesions that genuinely need in-person evaluation. A Cochrane review of teledermatology’s diagnostic accuracy for skin cancer similarly found that fewer than seven percent of malignant lesions were missed across the studies it examined, though the review also noted that a single reliable accuracy estimate across all studies could not be established given variation in methods and image quality.
Where an In-Person Visit Remains Necessary
Teledermatology has real limitations, and reputable providers are direct about them. Some diagnoses depend on touch, texture, or specialized equipment that a camera cannot replicate. A biopsy, required to confirm most skin cancer diagnoses, cannot be performed remotely under any circumstance. A handheld dermatoscope used during an in-person exam allows a dermatologist to examine layers beneath the skin’s surface with polarized light, a level of detail that even a high quality photograph does not fully capture, though smartphone dermatoscope attachments have narrowed this gap somewhat.
Full body skin exams present a particular limitation. One retrospective study from a Veterans Affairs health system found that among patients referred through teledermatology for a specific lesion, in-person follow up visits identified a substantial number of additional concerning lesions that had not been part of the original remote referral, roughly eight incidental findings for every ten lesions initially flagged. This suggests that a targeted remote review, however accurate for the lesion in question, is not a substitute for a comprehensive physical exam, particularly for patients with a personal or family history of skin cancer.
Complex or atypical presentations, extensive body surface involvement, and certain autoimmune skin conditions also tend to be better served in person. In these cases, the right outcome from a remote visit is often a referral rather than a diagnosis, since attempting one from incomplete information does the patient no favors.
Why Adoption Has Grown
Several practical factors explain the expansion of dermatology with telehealth in recent years.
Access is the most direct benefit. Many areas, particularly outside major metropolitan regions, have few dermatologists within a reasonable distance, and telehealth removes that geographic constraint. Speed follows closely behind access. Where a standard appointment might take weeks, a store and forward submission often returns an answer within one to three days, and some services offer same day live video visits for more urgent concerns.
Cost can also be a factor, since some virtual visits are priced lower than an in-person copay, particularly for patients without dermatology specific coverage. Time savings matter as well, given that a virtual visit removes the need to arrange travel, take time away from work, or coordinate childcare. Some patients also find it easier to discuss sensitive conditions, including those affecting the genital area, from a private setting and not a clinical office.
For chronic conditions, more frequent virtual check-ins can support better long term management, because patients are not limited to the cadence of full in-person visits to report changes or request adjustments to treatment.
Selecting a Telehealth Dermatology Provider
Given the number of services now offering virtual dermatology care, a few criteria are worth checking before choosing one.
Confirm that providers are licensed physicians, ideally board certified dermatologists, authorized to practice in the patient’s state. Licensing rules for telehealth vary by state, and a provider should be clear about which states it can serve rather than leaving this vague.
Check that the platform uses secure, HIPAA compliant technology to handle patient data and images. This is a baseline requirement for handling protected health information, not an added feature to look for.
Look at how the provider handles cases outside the scope of remote care. There should be a clear process for referring patients to in-person specialists when a condition requires physical examination, imaging, or biopsy, rather than defaulting to a remote diagnosis regardless of appropriateness.
Consider turnaround time and format. Store and forward visits suit patients comfortably waiting a day or two for a written response, while live video suits those who want real time interaction. Reviewing a provider’s stated response times can help set realistic expectations before booking.
Finally, confirm pricing and insurance coverage in advance, because coverage for telehealth dermatology visits varies by plan and has not yet been standardized across insurers. Some employers now include virtual dermatology as part of broader telehealth benefits, so it is worth checking existing coverage before paying out of pocket.
Looking Ahead
Ongoing developments are likely to extend what teledermatology can reliably do. Artificial intelligence tools are being tested as aids for flagging concerning lesions during triage, which could help direct higher risk cases toward faster in-person review. Smartphone dermatoscope attachments are also improving, narrowing the image quality gap between remote and in-person lesion assessment, as the teledermoscopy research cited above suggests.
Health systems and insurers appear to be moving toward broader integration of virtual dermatology with primary care, and some clinics already combine both formats, using telehealth for initial screening, routine follow up, and lower acuity concerns, while reserving in-person visits for procedures, biopsies, and full body exams.
Teledermatology is best understood as a complement to traditional dermatology care rather than a replacement for it. It expands access for patients who might otherwise go untreated, shortens the time to care for many common conditions, and helps direct more serious cases toward the in-person attention they require. For concerns such as acne, eczema, rosacea, or a new spot that needs a first opinion, a virtual visit with a qualified provider is often a reasonable and efficient starting point.
Getting the Most Out of a Virtual Visit
Preparation affects the quality of a remote assessment more than many patients expect. Beyond following a platform’s photo guidance, a combination of a wider shot showing surrounding skin and a closer shot showing texture or borders gives a provider more to work with than a single image.
A brief written timeline also helps. Noting when a condition first appeared and whether it has changed or spread gives the reviewing provider a sense of how the condition is behaving over time. Adding what treatments have already been tried and any apparent triggers fills in context that photographs alone cannot convey. Listing current medications and known allergies is equally important, since these can affect which treatments are appropriate.
Patients should treat a virtual visit with the same care as an in-person one, answering intake questions thoroughly, reporting any changes promptly, and accepting a referral to in-person care when a provider recommends it. That last point matters more than it might seem. The value of teledermatology depends on patients following through on referrals rather than treating a remote visit as the final word.
