Dermatology Remotely

Skin is one of the more telehealth-friendly specialties because much of it is visible. With good photos, many conditions can be diagnosed and managed remotely without an in-person visit. The exceptions matter, though, and the difference between a thoughtful teledermatology service and a glorified prescription mill is meaningful.

The short version

Conditions well-suited to remote care: acne follow-up, eczema management, common rashes, hair loss, melasma, rosacea, and stable plaque psoriasis.
Conditions not well-suited: full-body skin checks for cancer screening, suspected melanoma without imaging review, anything atypical or rapidly changing.
Async (photo upload + clinician response) and live (video) models both exist. Async is faster and cheaper; live can be more thorough.
The American Academy of Dermatology generally supports teledermatology with caveats; full skin exams remain in-person work.
Photo quality is the central variable. See photographing skin conditions.
Biopsy logistics — getting a procedure done locally if needed — is the test of whether a service has real clinical infrastructure.

Conditions that map well to telederm

Acne

Acne is one of the highest-volume teledermatology conditions, and it works. Initial assessment, prescription decisions (topical retinoids, topical antibiotics, hormonal management, oral antibiotics, or in some cases referral for isotretinoin which has additional in-person requirements through the FDA's iPLEDGE program), and follow-up adjustments are well-suited to async or live visits with good photos.

Eczema (atopic dermatitis)

Eczema flares are visible. Topical regimen adjustments, education about triggers, escalation to non-steroidal options or biologics for severe cases, and follow-up after starting a new medication are reasonable telederm scenarios.

Rosacea

Diagnosis of rosacea is largely visual, and management is medication-based.

Hair loss

Diffuse and patterned hair loss can often be assessed by photos and history. Some forms of scarring alopecia or sudden severe hair loss need in-person evaluation, sometimes with biopsy.

Stable psoriasis

Established psoriasis follow-up, including biologic monitoring (with periodic labs), is largely a telehealth-compatible workflow.

Common viral and inflammatory rashes

Many can be diagnosed visually: shingles, contact dermatitis, pityriasis rosea, common viral exanthems.

Mole monitoring (with limits)

For moles known to be benign, photo monitoring over time can be helpful. New moles, changing moles, moles in adults beginning to acquire new moles, and any lesion that does not look like the others ("ugly duckling") warrant in-person evaluation.

Conditions that are not well-suited

Full-body skin checks

The American Academy of Dermatology generally treats full-body skin exams for cancer screening as in-person work. Patients underestimate or miss lesions on the back, scalp, soles, and genital area. Dermatoscopy — the use of a handheld lens to evaluate lesions — is part of standard skin cancer screening and is not feasible from patient-supplied photos.

Suspected melanoma

Anything atypical, asymmetric, irregular border, multiple colors, large diameter, evolving — the classic ABCDE criteria — needs in-person assessment, dermatoscopy, and likely biopsy. A photo can prompt the visit but not replace it.

Other suspicious lesions

New, growing, bleeding, ulcerated, or rapidly changing lesions need in-person evaluation. The same applies to anything in chronically sun-damaged skin in older adults.

Severe or systemic skin disease

Severe drug eruptions, blistering disorders, serious bacterial infections (cellulitis with systemic symptoms, necrotizing infections), Stevens-Johnson syndrome, toxic epidermal necrolysis — all in-person or emergency department situations.

Async vs. live

Async (store-and-forward)

You upload photos and a description through a portal; a clinician reviews and responds, often within hours to a day. Cost-effective and convenient. The clinician is not interacting with you in real time, which works for stable problems and follow-ups but is less suited to nuanced new presentations.

Live video

You meet with a clinician on a video call. They can ask follow-up questions, look at additional areas, and discuss treatment plans. More expensive and slower to schedule than async. Often more appropriate for new diagnoses, complex problems, or when the patient needs to understand a treatment plan in depth.

Hybrid

Many services combine the two: async for routine refills and follow-ups, live for new evaluations or escalations.

Biopsy and procedural logistics

Sooner or later, a teledermatology relationship encounters a lesion that needs a biopsy. The question of how a service handles that distinguishes a real clinical practice from a marketing operation. Reasonable models include: a referral network of in-person dermatologists or primary care offices that can perform shave, punch, or excisional biopsies; a relationship with a national pathology lab and instructions for how to send specimens; or a transition to an in-person clinic where biopsies are done. A service that simply "recommends you see a local dermatologist" without any path is shifting the work to the patient and is a flag.

For prescription procedures done at home — for example, topical wart treatments — a service can manage these remotely. Procedures requiring local anesthesia, sterile technique, and tissue handling are not home procedures.

Skin of color considerations

Conditions can present differently across skin tones, and clinical training has not historically emphasized presentation in skin of color. A teledermatology service should have clinicians experienced in evaluating a range of skin tones, especially for inflammation (which presents differently on darker skin), pigmentation disorders, and certain types of skin cancer that are more common in or differently distributed in patients with skin of color. Photos in good daylight matter more, not less, for accurate assessment.

Clinician credentials

The American Board of Medical Specialties (ABMS) board certification for dermatology is a meaningful credential. Many teledermatology services use a mix of board-certified dermatologists, dermatology-trained PAs and NPs, and in some cases primary care clinicians. The mix is not necessarily a problem; the lack of transparency about the mix is. Verification through certificationmatters.org (the public ABMS portal) lets you confirm a specific clinician's board certification. State medical board license verification is similarly free and public. See choosing a remote dermatology service.

Prescriptions and refills

Most dermatology medications are non-controlled and prescribable remotely without difficulty. Isotretinoin (for severe acne) is the major exception: the FDA's iPLEDGE risk evaluation and mitigation strategy program has specific patient registration, monthly visit, and lab requirements. Some teledermatology services do isotretinoin within iPLEDGE constraints; others refer.

What to ask a teledermatology service

Will my photos be reviewed by a board-certified dermatologist, or by a PA or NP?
What happens if I need a biopsy?
Do you use async, live, or both?
How are records shared with my primary care or in-person dermatologist?
What is your protocol if you are concerned about cancer?
What is the cost of an initial visit and follow-ups?
Are visit notes available in the patient portal?

What you can do to make a visit useful

Take three photos per area at three distances, plus one with a scale reference. See photographing skin conditions.
Photograph in natural daylight, no flash, no makeup or treatment beforehand.
Write a short history: when it started, what it feels like, what makes it better or worse, what you have tried.
Upload through the secure portal, not by text or email.
Bring a list of medications and known allergies.
For lesions you are watching, include earlier photos for comparison if you have them.

When this is not enough

Anything resembling a skin emergency — rapidly spreading redness with fever, severe blistering, mucous membrane involvement, severe pain — is in-person or emergency care. Anything that looks like skin cancer needs in-person evaluation and likely biopsy. Full-body skin checks remain in-person work. See when telehealth is not enough.
