Online dermatology is often enough for common, non-urgent problems and follow-ups, but an in-person dermatologist is better when the diagnosis is uncertain or when a lesion may need a biopsy or procedure. Teledermatology has shown comparable results to in-person care for several conditions like acne, psoriasis, and some eczema/rosacea follow-ups, but it is less reliable for skin cancer checks, changing moles, and other cases needing hands-on examination[1][3][5][6][8][9].
Use online dermatology when the issue is:
- Acne follow-up or treatment adjustments, where studies found outcomes comparable to in-person care[6][10].
- Stable psoriasis or similar chronic inflammatory rashes, where online care was equivalent to in-person care in randomized trials[5][8].
- Common rashes, eczema, rosacea, hives, dandruff, itching, or medication refill visits, especially when the condition is already known and not severe[1][11].
- A triage visit to decide whether you need an in-person appointment, since teledermatology can be effective for screening and routing patients appropriately[2][3][9].
Choose in-person dermatology if you have:
- A single changing mole, dark spot, or any lesion that may need biopsy or closer inspection[1][11][13].
- A need for full-body skin cancer screening[11][13].
- A new, unclear, or rapidly changing rash where the diagnosis is uncertain[2][13].
- Severe symptoms such as fever, pain, blisters, drainage, infected wounds, large ulcers, or feeling generally ill[11].
- Conditions where a procedure is likely, such as biopsy, cryotherapy, excision, or detailed dermoscopic examination[1][12][13].
A practical rule: if the problem is visible, common, stable, and already diagnosed or strongly suspected, online care is often sufficient; if it is changing, suspicious, painful, severe, or may need a procedure, in-person care is the safer choice[1][2][11][13].
