A dark spot analyzer estimates the amount and distribution of visible pigment on a face from a photograph. Clinically, pigment is assessed by a trained eye, by standardised photography under controlled lighting, or with imaging that isolates melanin from other chromophores. An AI analyzer estimates the same property from a normal photograph, which trades some precision for being repeatable at no cost.
This distinction is the main reason to score pigment independently. Both produce the same complaint from a customer, uneven tone, and they need opposite treatments on opposite timelines.
| Pigment | Vascular redness | |
|---|---|---|
| What it is | Melanin deposited unevenly | Blood vessels, dilated or inflamed |
| How it behaves | Stable across days and weeks | Changes within hours, with heat and stress |
| Under pressure | Stays put while surrounding skin blanches | Blanches, then refills |
| How fast it responds | 3 to 6 months | 1 to 4 weeks |
| What it needs | Sun protection, vitamin C, niacinamide, retinoid | Calming, barrier repair, trigger removal |
| What makes it worse | UV exposure, inflammation, aggressive treatment | Heat, actives, over exfoliation |
Find and Score Dark Spots in Three Steps
No device, no clinic visit. One photo maps where pigment sits and scores how much of it there is.
Capture
Take a selfie or upload a photo in even indirect light with a bare face. A guided camera flow checks lighting first, because pigment reads differently under every light source and inconsistent capture ruins any later comparison.
Detect and Score
The engine scores pigment as an independent value and maps where individual spots sit on the face, alongside 28 skin diagnostics across 16 skin concerns. Results return in seconds.
Route and Re-scan
Route the customer on how pigment scores against redness and texture, then prompt a re-scan at ninety days under matched lighting. Pigment is a three to six month project and saying so up front is what keeps customers on it.
Why Brands Score Pigment Separately
Dark spots are the most commercially valuable concern in skincare and the easiest to misdiagnose from a photo.
Separates Brown From Red
Pigment and vascular redness both read as uneven tone to a customer and need opposite treatments. Scoring them as independent values is what makes the recommendation correct rather than plausible.
The Sign Sun Protection Pays Out On First
Published work scoring 22 clinical signs found pigmentation significantly higher in sun seeking women in every age group, making it the most specifically sun driven sign. That makes it the strongest evidence base for an SPF recommendation.
Catches the Pattern That Punishes Escalation
Patchy symmetrical pigment behaves differently from scattered spots and worsens under aggressive treatment. Mapping where pigment sits, not just how much there is, is what lets a flow route that case to caution instead of to a stronger acid.
Validated Across Skin Tones
Pigment assessment is where training data breadth matters most. The engine is trained on 70,000+ clinical images spanning the full Fitzpatrick range and has been examined in peer reviewed validation across skin types.
| Business outcome | Why pigment scoring delivers it |
|---|---|
| The largest skincare category | Brightening and tone correction is where the spend concentrates |
| Fewer abandoned routines | A stated three to six month timeline stops customers quitting at week six |
| The strongest evidence base for an SPF upsell | Pigment is the most sun specific sign and prevention is RCT supported |
| Fewer wrong purchases | Separating pigment from redness stops customers buying the opposite treatment |
| Avoiding the melasma mistake | Routing a symmetrical pattern to caution prevents a worsened outcome and a bad review |
| A clean referral path | Handling changing spots responsibly is the cheapest credibility available |
Distribution matters as much as quantity because one pattern punishes the very treatment that helps the others.
| Pattern | What it looks like | Treatment note |
|---|---|---|
| Solar lentigines | Scattered flat brown spots with defined borders on exposed areas | Responds to sun protection plus actives over months |
| Melasma | Larger symmetrical patches across cheeks, forehead and upper lip | Worsens under aggressive treatment. Route to caution |
| Post inflammatory hyperpigmentation | Brown marks exactly where spots or injuries were | Fades over 3 to 12 months. Prevention is treating the acne |
| General mottling | Patchy tone without discrete spots | Tone evenness products, measured in months |
| Anything changing | A spot altering in size, shape, colour or border | Outside cosmetic scope. Refer to a clinician |
Mapping where pigment sits, rather than only how much there is, is what allows a flow to route the second row to caution rather than to a stronger acid, and the fifth row out of the funnel entirely.
What the Pigment Score Tells You
Read in combination, the spots score names a cause and a timeline instead of describing a symptom.
High Spots With Normal Redness
A clean pigment case. Route to vitamin C, niacinamide and daily sun protection, and say three to six months out loud rather than letting the customer set their own expectation.
High Spots With High Texture
Retinoid led routine, with texture promised as the early visible win. Texture moves in weeks and pigment in months, so leading with the fast one buys patience for the slow one.
High Spots With Elevated Redness
Calm the skin before treating the pigment. Acids and tyrosinase inhibitors on inflamed skin generate new pigment, which moves the customer backwards while they are paying to move forwards.
Any Spot the Customer Says Is Changing
Refer out, immediately and unambiguously. Cosmetic pigment scoring is not built or validated to assess moles or lesions, and building that referral path properly is the cheapest credibility a brand can buy.
Pigment Is a Three to Six Month Project
Dark spots are the concern customers are most willing to spend on and least willing to wait for, which is why so many pigment routines get abandoned at week six. Surface pigment responds over three to six months, deeper and long standing damage less completely. Returning a score with a stated timeline, and prompting the re-scan at ninety days rather than weekly, is what turns an impatient purchase into a completed routine.

A tool that detects where pigment sits on the face from a photograph and scores how much of it there is. Perfect Corp.'s dark spot analyzer returns pigment as an independent value rather than blending it into a general tone rating, which is what allows dark spots to be told apart from vascular redness.
There is no universal target, because scores are comparable within one system rather than across systems. A higher score means more even pigment. What matters is how spots sit against your own redness and texture scores, and which direction they move across scans taken ninety days apart under matched lighting.
It is a consistent estimate from visible signs rather than a measurement of melanin. The engine is dermatologist verified, trained on 70,000+ clinical images and examined in peer reviewed validation across Fitzpatrick skin types. It is a cosmetic assessment and is not validated to evaluate moles or lesions, which require a clinician.
Yes. The pigment score is returned through the same skin analysis API as the other concerns, as structured data you can route product recommendations on. One integration covers web, mobile app and in store tablet, and Perfect Corp works with 800+ brand partners on experiences of this kind.
Yes. You can run a scan in the online skin analysis demo with no download and no account, and see pigment returned alongside the full set of 28 skin diagnostics across 16 skin concerns. Contact sales for API access, volume pricing and validation detail.
