It shows its work.
Every score sits on your own photo, zone by zone, so you can see where a number came from instead of taking one figure on trust.

The full report
Everything the score is made of.
Your overall level and score are free. The full report is everything underneath them.
A zone map on your photo
Your forehead and both cheeks drawn on your own face and tinted by level, so you can see where each number comes from.
A score for each zone
Forehead, left cheek and right cheek, each with its own score out of 100 and its level. Nose, chin and jaw are not scored in this version.
The closest lesion type, where there is redness
Where a zone shows redness, an image model looks at close crops of the inflamed spots it finds and names the closest of five types: blackheads, whiteheads, papules, pustules or cysts. Clear skin gets no label, and a match is never a diagnosis.
A treatment ladder
The care options in the 2024 American Academy of Dermatology acne guideline, grouped by how firmly the evidence supports each one, to discuss with a dermatologist.
A morning and evening routine
Cleanse, treat, moisturise and protect, with the active ingredients to look for. If you tan easily or have darker skin, it adds care against the dark marks acne can leave. Ingredients, never brands.
A printable report and a dermatologist summary
Print the report or save it, and copy a short summary in a dermatologist's terms to bring to an appointment.

Why it is different
A skin score you can check.
Honest about darker skin.
Your skin type is asked, never guessed from the photo. Tell us how your skin reacts to sun and your routine adds care against the dark marks acne can leave, which often bother people as much as the acne itself. And we say plainly where the analyser reads darker skin less well.
58.2%
of patients consulting a dermatologist for acne in an Asian Acne Board study had dark marks left by acne.
Abad-Casintahan et al., 2016. 324 patients across seven Asian countries. A figure for people who saw a dermatologist, not for everyone with acne.
A dermatologist's vocabulary, not a dermatologist's verdict.
Zone scores, closest-match lesion types and a treatment ladder set out in the terms of the 2024 American Academy of Dermatology guideline. It never claims an IGA, GAGS or Hayashi grade: those scales are built for a trained examiner, and GAGS also scores the chest and back.
Real output
Clear to severe, unedited.
Each card is the analyser's own result on a sample face, with nothing retouched. Forehead and cheeks are scored and tinted; nose, chin and jaw are not scored in this version.

The darker the skin, the less contrast redness has in a photo, so acne on darker skin can read a level lower than it looks. If your skin is darker, treat a low result as a floor, not a verdict.
Honest limits
What a photo can and cannot see.
What the analyser does not see, with the studies behind the limits that have one.
The Acne Analyser is for cosmetic awareness. It is not a diagnosis and does not replace an examination by a dermatologist. If your acne is painful, leaving scars or getting worse, see one.
Blackheads and whiteheads are not red.
The analyser reads redness, so a face with only blackheads and whiteheads can read Clear. Photographs miss small, non-inflamed spots in general. These types are matched only from a close-up photo of a single spot. (Bae et al., 2024)
Nose, chin and jaw are not scored.
Stubble, lips and nostrils read as redness there, so this version leaves those zones out. Acne along the jawline does not change your result.
Dark marks are not measured.
The marks old spots leave behind are not scored. Even dermatologists disagree on whether a mark is redness or a dark mark, most of all when active acne is present. (Goh et al., 2014)
Darker skin can read lower.
Redness shows less contrast on darker skin, so the same acne can score a level lower. Research on software that grades acne from photos is also narrow: a 2025 review found most studies used photos of only a few ethnic groups. Read a low result on darker skin with extra caution. (Traini et al., 2025)
A photo cannot feel depth.
Nodules and cysts are judged partly by touch and depth, which no camera can supply. Treat a cyst match as a reason to see a dermatologist, not as a finding. (Bae et al., 2024)
Software is not a dermatologist.
The Acne Analyser has not been through a clinical study, so it makes no claim about how often it agrees with one. A dermatologist's examination remains the standard.

Questions, answered.
No. The Acne Analyser is a cosmetic awareness tool. It describes what your photo shows, zone by zone, and points to the kinds of care the 2024 American Academy of Dermatology guideline describes. It does not diagnose acne or any other condition, and it does not replace a dermatologist.
The analysis runs in your browser, so your photo is not uploaded to be analysed. If you choose to save a scan to your history, a small thumbnail and your result are stored in your account so your history can show them. Your full-size photo is not part of a saved scan.
Face a window for even, natural light. Use clean, bare skin with no makeup or tinted sunscreen, pull your hair back, and hold the phone straight on so your whole face, forehead to chin, is in frame. Turn off beauty filters. JPEG, PNG and WebP photos all work.
Every analysis shows your overall level and score. The full report adds the zone map on your photo, a score for your forehead and each cheek, the closest-match lesion type where inflamed spots are found, a treatment ladder set out against the 2024 American Academy of Dermatology guideline, a morning and evening routine, a printable report, a summary for your dermatologist and your scan history.
Only where a zone shows redness. An image model looks at close crops of the inflamed spots the analyser finds and names the closest of five types: blackheads, whiteheads, papules, pustules or cysts. Clear skin never gets a type. It is a closest match, not a diagnosis. Blackheads and whiteheads are not red, so they are matched only from a close-up photo of a single spot.
In those zones, stubble, lips and nostrils look like redness to a camera, and the scores they produced were misleading. So this version scores your forehead and both cheeks, and shows the nose, chin and jaw as not scored. Acne along the jawline does not change your result, so mention it to your dermatologist.
It runs on every skin tone, but redness, which is what it measures, shows less contrast on darker skin, so the same acne can read a level lower. Your skin type is never guessed from your photo: you can answer one optional question about how your skin reacts to sun, and your routine adds care against dark marks. On darker skin, read a low result with extra caution.
Yes. The full report includes a printable report and a short plain-text summary in a dermatologist's terms, which you can paste into a message or bring to an appointment. It is a starting point for that conversation, not a substitute for the examination.
One payment opens the full report for 24 hours. Every analysis you run in that window shows the full report, and the scans you save stay in your account. There is no subscription and nothing renews.
