Skin profile
Type, undertone, texture, hydration — read from natural light and macro detail.
Powered by MaIA
The AI that reads beauty profiles.
MaIA analyzes selfie data to build a detailed beauty profile for each consumer — skin type, undertone, hair profile, sensitivity, and product preferences. When you submit a product for sampling, MaIA maps its attributes against our consumer database to identify the highest-fit recipients. And because MaIA was built from hundreds of thousands of Brazilian consumer selfies, it reads Latin American skin tones and undertones accurately — where beauty AI trained on mostly US and European faces falls short.
What MaIA reads
Four signals. One precision match.
Hair profile
Strand type, density, condition — from style cues and texture analysis.
Sensitivity & needs
Reaction history, ingredient flags, current concerns.
Preferences
Finishes, formats, brand affinities — built from purchase and browse history.
How it works
From product brief to perfect match.

White-label MaIA
Two products. One engine. Inside your store.
Implement MaIA in your own e-commerce — to lift conversion at the moment of decision, or to run one-to-one beauty consultations at infinite scale. Same engine that powers glam and Men's Market, ship-ready as two complementary products.
Reads the customer.
Your customer takes a selfie on your site. MaIAScan identifies skin type, undertone, hair profile, sensitivity markers, and beauty preferences — the input layer for everything that happens next.
Drop it into your product page, your checkout, or your post-purchase flow. The customer gets to know themselves; you get the data to recommend with confidence.
Closes the sale.
Pairs MaIAScan's customer profile with your product catalog to run a one-to-one beauty consultation. Your customer asks 'what works for my skin?' — MaIAChat answers with specific SKUs from your inventory, explains why each one fits, handles objections, and moves the conversation toward a confident purchase.
Replaces the chatbot. Replaces the static FAQ. Replaces the in-store beauty advisor — at infinite scale, 24 hours a day.
API or front-end widget. Works on Shopify, VTEX, custom stacks. Your design system stays intact; MaIA powers the logic underneath.

FAQ
Frequently asked questions
What is AI-guided product sampling?
AI-guided sampling sends product samples to the consumers most likely to love them — and measures what happens next. B4A's MaIA matches your product's attributes against more than 1.2 million Brazilian consumer beauty profiles, so samples reach people by skin type, hair profile and preferences, and every delivery returns ratings, reviews and repurchase signals.
How does B4A decide who receives my product?
MaIA, B4A's beauty AI, builds each consumer's beauty profile from selfie analysis and real behavior — skin type, undertone, hair profile, sensitivity and product preferences. Your product is profiled by category, ingredients and target fit, then MaIA cross-references both to select the highest-fit recipients — not just an age or location segment.
Through which channels are samples delivered?
Samples ship through B4A's own consumer channels in Brazil: glam and Men's Market monthly subscription boxes, gifts included with e-commerce orders, and loyalty-point redemptions. Consumers receive your product in a context they already trust, then rate and review it — closing the feedback loop.
What data do brands get from a sampling campaign?
Structured, consumer-level feedback: product ratings, written reviews and repurchase signals, all matched to detailed beauty profiles. Because B4A knows each recipient's skin and hair profile, brands see not just whether people liked the product, but exactly who it worked for — evidence that guides launches, claims and channel strategy.
Can I use MaIA inside my own online store?
Yes. White-label MaIA ships as two products: MaIAScan, which reads a customer's skin and hair profile from a selfie on your site, and MaIAChat, which runs one-to-one beauty consultations and recommends products from your own catalog. Integration is via API or front-end widget and works on Shopify, VTEX and custom stacks.
