The best AI skin analysis app depends on what you want it to do
Of 10 skin analysis tools, 7 are run by a brand that recommends its own products, and only YouCam and L'Oreal's Skin Genius publish an accuracy figure. Choose by goal (trend, routine or acne) and by what happens to your selfie.
Read on the makers' own pages on 23 October 2026, 7 of 10 popular AI skin analysis tools recommend their maker's own products, 2 publish an accuracy-type figure, and none publishes accuracy by skin tone.
The one that matches your goal, read as a brand's shop window:
To watch your skin over weeks: Skin Bliss, whose App Store privacy label lists no photos, or YouCam's free web scan.
For a routine: the free tool of a brand you already use, such as L'Oreal Paris Skin Genius, which says it deletes your selfie after the analysis.
For acne: La Roche-Posay Spotscan+, which grades acne 0 to 5 and sends grade 3 and above to a dermatologist.
To check products rather than your face: FeelinMySkin, or an ingredient checker.
Remember what you are buying into: 7 of 10 recommend their own range, and the accuracy they publish is thin; see how accurate AI skin analysis apps are.
Which skin analysis app fits what you want?
Start from the job, not the brand. A scanner that repeats itself is good for tracking; a brand tool is good for a routine from that brand; an acne grader does one thing. Under each goal, the hot box names the tool with the clearest statement that your selfie is deleted or never collected.
Pick by goal10 tools, read 23 October 2026
Tools sorted by what they are for. "If your selfie matters" picks the first tool in that branch with a deletion or no-photo statement on its own page or App Store privacy label. Proven sits under products because it builds a formula from a quiz, not a photo.
Who sells what, and what do they publish?
Almost every scanner is a shop. 7 of the 10 tools recommend the maker's own range: L'Oreal Paris, La Roche-Posay, Neutrogena, Olay, Dermalogica, Clinique and Proven. That is not a scandal; it is the business model, and the brand tools are upfront about it. It does mean the routine you get is the best match within one catalogue. The independent case shows why it matters: in Which?'s test of the Boots tool, reported 15 October 2026, L'Oreal was recommended 214 times and Cosrx 154 across 30 testers. Boots has since taken its tool offline.

worth knowing
not stated or not applicable
"Accuracy figure" counts any published number: YouCam's is an 80% correlation with dermatologist evaluations (its page also gives a 95% test-retest rate), Skin Genius's is "up to 95% accurate" against a live dermatologist consultation. Neither is broken down by skin tone. "Linked to you" is the YouCam Makeup app's App Store label for photos; Perfect Corp's policy says most of its services store no facial photo.
What does each skin analysis tool do?
YouCam (Perfect Corp): best free scan for tracking
Perfect Corp's free web skin analysis needs no registration, scores 15+ concerns from 1 to 100, and publishes more than most: an 80% correlation with dermatologist evaluations and a 95% test-retest reliability rate. The second is a repeatability figure, which is exactly what you want for tracking. Perfect Corp sells no skincare of its own; its engine also runs inside brand tools. The YouCam Makeup app is chiefly a makeup and photo editor; its listing does not describe skin analysis, though a user review on it mentions a free "skin score".
L'Oreal Paris Skin Genius: best brand routine with a stated deletion
Skin Genius says it rates 8 attributes, compares your selfie with more than 10,000 clinically graded images, and builds a routine from more than 30 L'Oreal Paris products, with $3 off afterwards. It is free and says "up to 95% accurate compared with a live dermatologist consultation", without the method. The page says the selfie is deleted after the analysis; its information notice says derived results are kept up to 3 years.
La Roche-Posay Spotscan+: best for acne only
Spotscan+ takes three selfies, counts and sorts spots, blackheads and marks, and gives a GEA grade from 0 to 5, advising a dermatologist from grade 3. L'Oreal cites a clinical study of 1012 acne patients supervised by 3 dermatologists, without a headline figure, and says pictures are deleted from the server after the analysis. It recommends up to four La Roche-Posay products.
Neutrogena Skin360: an established brand tool on a new engine
Skin360 moved to Haut.AI's engine in September 2025, according to Haut.AI's announcement: eight indicators (hydration, smoothness, tone evenness, radiance, firmness, dark spots, wrinkles, clarity) rolled into a score from 1 to 10, then a Neutrogena morning and evening regimen. In February 2026 Kenvue agreed a proposed $4.7 million settlement of an Illinois biometric privacy class action over earlier versions of the tool, ID Tech reported, without admitting liability; terms include deleting class-period face images and adopting written consent and retention policies.
Olay Skin Advisor: check what it scans first
The Skin Advisor page now says only that it "analyzes your skin using advanced technology" and does not say whether it takes a photo. Its ready-made routines are all Olay. No accuracy or selfie statement appears on the page.
Dermalogica Face Mapping: best if you want a human after the scan
Face Mapping looks at breakouts, dehydration, oiliness, redness, wrinkles, under-eye darkness, pigmentation and ageing, and lets you take a quiz instead of uploading a selfie. It offers access to professional skin therapists, says the data is not sold, and gives no retention period.
Clinique Clinical Reality
Clinical Reality starts with a phone scan, cites "55+ years of dermatological research and 3+ million scans", and returns personalised Clinique recommendations. The page calls the tool "our advanced diagnostic"; like every tool here it is a cosmetic recommender, not a medical diagnosis.
Skin Bliss: best app for progress photos
The Skin Bliss app uses AI face scanning to profile your skin and compares later scans with your first. It sells no products of its own. Its App Store privacy label lists no photos or face data. Pro costs $6.99 a month or $34.99 a year, and a single Face Scanner purchase is listed at $1.99.
FeelinMySkin: scans products, not your face
FeelinMySkin points the camera at a product and returns a Skin Match Score from a database of 150,000+ products, with a skin diary and AI comparison of your own progress photos. No own brand; PRO from $4.99 a month or $18.99 a year at its lowest listed prices.
Proven Skincare: a quiz, not a scan
Proven builds custom formulas from a skin quiz and sells them on subscription; its homepage offers 25% off a first order. No photo is involved, so the selfie questions do not apply.
What do the paid skin apps cost?
None of the brand tools here shows a price on its page, and Skin Genius says outright that it is free. Paying comes in with the standalone apps, and paying yearly is much cheaper if you will keep using one: monthly payments overtake the yearly price by month 6 at the latest. The cheapest year is FeelinMySkin PRO at $18.99.
A year of each paid tierlowest listed US App Store prices, read 23 October 2026
YouCam Makeup Premium: $5.99 a month or $31.99 a year, so yearly saves $39.89, and monthly payments pass the yearly price in month 6.

Skin Bliss Pro: $6.99 a month or $34.99 a year, so yearly saves $48.89, and monthly payments pass the yearly price in month 6. FeelinMySkin PRO: $4.99 a month or $18.99 a year, so yearly saves $40.89, and monthly payments pass the yearly price in month 4. The App Store lists several prices per period without saying which is current; these are the lowest of each. YouCam's subscription is for the makeup app; the web skin scan is free.
Before you scan: five questions
1. What do I want: a trend, a routine, or acne help?
2. Whose products will it recommend? (On 7 of
these 10 tools, the maker's own.)
3. Does it publish an accuracy figure, and is it
accuracy or just repeatability?
4. What happens to my selfie: deleted, kept, or
not stated?
5. Same window, same time of day, no make-up: the
only way two scores are comparable.
Which one should you use?

How we chose and checked
Method
We listed the AI skin analysis tools named by Which? and by the makers themselves, kept those with a live maker page or App Store listing on 23 October 2026, and read each maker's own page for what it measures, whose products it recommends, any accuracy figure, any skin-tone breakdown and what happens to the selfie. Prices are from the US App Store the same day. Tools whose pages we could not confirm as live were left out. SlipperSkin did not scan with these tools; the comparisons are of what the makers publish. Recommendations are cosmetic, not medical.
