Structured response
Skin, hair and photo quality. In a single JSON.
Every field comes with a value and a confidence. You decide what to show, what to confirm with the customer, and what to feed your product rules.
skin.type · skin_scan.*Skin type and condition
Seven Skin Scan metrics, 0 to 1: redness, oiliness, texture, pores, spots, hydration and pigmentation.
hair.color · hair.structureHair
Color and structure — straight, wavy, curly, coily — to recommend the right care.
quality.blur · quality.lightingPhoto quality
Blur, lighting and framing — so you can ask for another photo before a wrong recommendation.
questionnaire.suggestionsA quiz filled by the photo
Suggested answers for your profile questionnaire, so the customer confirms instead of typing.
*.confidenceConfidence on every field
Low confidence? The API tells you, and you ask for confirmation. No silent guessing.
Why MaIA Scan
Trained where beauty is diverse.
Hundreds of thousands of real selfies
Brazilian consumers, across the full range of Brazilian skin tones and hair types — not a mostly white dataset.
In production at glam and Men's Market
The same engine serving Latin America's largest beauty clubs, now inside your brand.
Privacy by design
Consent required. Configurable image retention. No facial recognition, no protected-trait inference, no medical diagnosis.
Keeps improving
Three model families — color, skin condition and hair structure — retrained with new data and human validation.
MaIA consultant · sales by conversation
A beauty consultant who knows the customer before she answers.
The MaIA consultant uses the MaIA Scan profile — skin, hair and preferences — to talk with each person the way a good in-store consultant would: understand what they want, recommend what makes sense from your catalog, and explain why. On WhatsApp, on the product page or inside your app. It is the same technology as the assistant serving glam.
Where she works
On your brand's WhatsApp
The customer sends a selfie. The consultant builds the profile, recommends products with a direct link to the cart, follows the routine — and says when it's time to restock.
On the product page
An "Is this product for me?" button on every PDP. The consultant answers with the person's profile: whether it fits, why, and what fits better if it doesn't.
In the site and app chat
Before deciding, the person asks. After buying, the consultant teaches how to use it, builds the routine and resolves the doubt that would have become a return.
Why this converts
Certainty before the click
Doubt stalls the purchase. An answer made for that skin, at that moment, removes the doubt on the spot — no waiting for support.
The right shade on the first purchase
Foundation, concealer, hair color: with a real profile the person gets it right the first time. Fewer exchanges, fewer returns, less frustration.
A basket that makes sense
The consultant recommends what completes the routine — not the priciest item. Cross-sell the customer recognizes as help.
Repurchase at the right moment
She knows what the customer uses and when it runs out. The reminder arrives before the empty shelf — and before the competitor.
Data that flows back to the brand
Every conversation becomes signal: recurring doubts, objections, products people ask for that aren't in the catalog, shades that don't exist yet.

Talk about a projectFrequently asked questions
What your brand should know before integrating.
A beauty profile as JSON: skin tone and undertone, skin type, seven Skin Scan metrics (redness, oiliness, texture, pores, spots, hydration and pigmentation), hair color and structure, photo-quality checks and a confidence value for every field.
No. The API does not identify people, does not create biometric templates for identification and does not match faces. It also does not infer protected traits or make medical diagnoses — it is cosmetic analysis for personalization.
A session is one complete analysis call: a required front photo and, optionally, a side photo sent in the same session. Packages are sold by number of sessions, with no monthly fee.
Consent is required before any analysis. Raw-image retention is configurable and structured results are stored with model and pipeline versions. You decide what to show and what to confirm with the customer.
The API is the same for any country; the site and support are in Portuguese, English and Spanish. The model was trained on hundreds of thousands of Brazilian consumer selfies, which makes it uniquely strong for Brazilian and Latin American skin.
