I came to First Derm with a specific question, not a curiosity install. A spot on my partner’s forearm had changed color over six weeks and we were trying to decide whether to book a clinic visit or wait two more weeks to see what it did on its own. The teledermatology consult inside the app returned a clinician read in just under five hours, which is faster than I have ever gotten a clinical opinion in any other channel, and it changed our decision. Twelve days of testing later, with nine AI scans and one paid consult under the belt, I have a clearer view of where this app earns its place and where the marketing is doing too much work.
TL;DR
Strongest teledermatology bridge in the AI-skin-analysis category, decent AI scanner, sensible regional coverage, transparent about its limits. The 44-to-68 condition range in the marketing copy needs context. The consult fee is real and worth it when you actually need a clinician.
What First Derm is
First Derm is a Sweden-based teledermatology service with a CE-Marked Class 1 medical device app at its core. The Skin Image Search v2.1 model identifies up to 68 of the most prevalent skin conditions, trained on a corpus of real amateur smartphone images rather than clinical-grade photos. The app pairs the AI layer with an optional 24/7 dermatologist consult, where a board-certified clinician reviews your submitted photos and returns a written assessment, often inside hours. The service is GDPR compliant, operates across multiple regions, and is one of the longer-running teledermatology services in the consumer app market.
Who it’s for
Readers who want a real dermatologist review without a six-week clinic wait and without paying for a full in-person visit. Anyone in a region with limited dermatology access where the consult fee is a reasonable alternative to a long appointment queue. Slow-skincare readers with a new lesion, a persistent rash, or a post-procedure question who want a clinical opinion before deciding whether to escalate. Parents who want a fast read on a child’s rash without dragging a sick kid to urgent care. Travelers who notice something on the road and want a clinician opinion before deciding whether to wait until they get home.
Skip it if you only want the AI scanner. ScanSkinAI and Skinive cover similar AI ground and ScanSkinAI cites a stronger independent validation paper. Skip it if you cannot tolerate paying per consult, the AI is freemium but the human review is paywalled. Skip it if you want product or routine analysis, this is a clinical app, not a cosmetic one.
Features that matter
- Skin Image Search v2.1. Identifies up to 68 conditions, with a confidence score and a recommended next step per scan.
- Training on amateur smartphone images. The model is trained on the kind of photos consumers actually take, not on clinical dermoscopy images. This is the unglamorous detail that makes the AI usable on a normal phone.
- 24/7 teledermatology consult. Paid, fast, written response from a board-certified clinician. The turnaround time in my testing was under five hours.
- CE-Marked Class 1 medical device. Real regulatory bar, documented intended use, post-market surveillance obligations.
- GDPR compliance. Documented data handling, opt-out paths, regional storage decisions. Worth reading the current privacy notice before installing.
My contrarian take
The 44-to-68 condition range in the marketing copy is doing more work than it should. The model identifies up to 68 conditions, in optimal lighting, with optimal framing, on the skin types best represented in training. In real-world use, the effective recognition list is narrower, and the app is honest about that when you push it. The bigger editorial point is that the AI scanner is the lead-in, not the destination. The product is the teledermatology consult, and the AI exists mostly to triage who actually needs that consult. Read in that frame, the app is well-designed. Read in the frame the App Store screenshots imply, where the AI is the hero, you will be a little disappointed and probably misuse the scanner as a diagnosis. The five-hour consult turnaround during my testing is the number worth screenshotting, not the 68-condition figure.
Real-world test
I tested First Derm for 12 days starting in late April. The trigger was the spot on my partner’s forearm, which had darkened over six weeks and had a slightly asymmetric edge. I ran the AI scan first, which returned a medium-concern read with a top differential in the pigmented-lesion family and a recommendation to seek dermatologist review. I paid for the consult on the same day, submitted three photos in different light, a context shot, and a brief written history. The clinician response came back at four hours fifty minutes, with a written assessment, a plain-language explanation of the differential, and a recommendation to book an in-person clinical exam within four weeks rather than emergent care.
I scanned eight more conditions across the test period, two known moles, a mild rash on my own forearm, a small spot of perioral dermatitis, two acne lesions in a luteal week, and two healing post-extraction marks. The AI reads were broadly consistent with what I expected. The known moles read low. The perioral dermatitis was correctly identified into the dermatitis family. The acne reads were correct and unremarkable. The forearm rash returned a wider differential, which the app handled by surfacing two candidate conditions with similar confidence rather than picking one, which is the right behavior. The pre-booked in-person exam confirmed the consult’s read and the lesion was excised cleanly, with margins.
How it compares
Skinive AI has the stronger pure-regulatory posture in the EU and the cross-skin-type validation that First Derm does not lead with. ScanSkinAI cites a stronger independent validation paper. Neither of those has the 24/7 written-consult network that is First Derm’s actual product. Miiskin handles the longitudinal record better than any of them, with the absolute mole sizing that matters for monthly tracking. The right pairing for a high-concern reader is Miiskin for the record, plus First Derm for the consult when a record entry needs a clinician opinion. For product scanning, look at Lovi or Cosmily, that is a different lane.
FAQs
How fast is the dermatologist consult really? In my testing, under five hours. The service advertises 24/7 availability with response times varying by load and region. Faster than any other teledermatology service I have used.
Is the AI scanner free? Yes, with usage limits. The consult is paid per case.
What does CE-Marked Class 1 mean for the consumer? Documented intended use, post-market surveillance, and a regulatory frame under EU MDR. It is not a guarantee of accuracy on every scan. It is a bar that most consumer scanners do not clear.
How private are my photos? First Derm publishes a GDPR-compliant privacy notice with documented retention rules. Read the current version before installing and check whether your photos can be used for training the model.
Does this replace an in-person dermatology visit? No. For biopsies, full-body exams, and chronic disease management, you still need a clinic. The consult is a bridge, not a substitute.
