Nigerian AI App Analyzes Skin Tones Others Miss

Skincare advice shouldn't come from guesswork and influencers, and a Nigerian startup is using AI to change that.

Oyster, founded in August 2024 by Jude Chikezie, launched an app that analyzes your skin through your phone camera and recommends products tailored to what it sees. The platform emerged from a gap Chikezie noticed while working with major beauty brands across Africa: people with darker skin tones struggled to find accurate skincare guidance.

The app works simply. Users answer questions about allergies, budget, and skin concerns, then take three photos of their face from different angles. Within seconds, Oyster divides those images into twelve segments and analyzes thirty-three different skin parameters, from acne severity to hydration levels.

What makes Oyster different is its training data. The AI model, built using Google's Gemini technology, learned from 48,000 skin scans representing the full Fitzpatrick scale of skin tones. Chikezie worked directly with dermatologists and aestheticians to build datasets that actually include darker skin, addressing a persistent blind spot in beauty technology.

The system grades skin conditions using the same frameworks dermatologists use in clinical practice, like the Global Acne Grading System. Users get a skin health percentage score and a personalized daily routine, complete with product recommendations from partner retailers.

The Ripple Effect

Beyond individual skincare routines, Oyster represents progress in AI equity. Tech tools trained primarily on lighter skin tones have historically failed people of color, from soap dispensers that don't detect darker hands to medical imaging that misses conditions on darker skin. By intentionally building datasets that represent Africa's diverse skin tones, Oyster is helping correct that imbalance.

The app isn't perfect. Multiple scans can produce slightly different results, and Chikezie is clear that Oyster works as a triage tool, not a replacement for dermatologists. For serious skin conditions, professional medical advice remains essential.

But for millions of people who've never had access to personalized skincare analysis, Oyster offers something valuable: a starting point based on their actual skin, not someone else's viral routine. The app lets users track changes over time and includes an AI assistant to answer questions based on their specific scan results.

Chikezie's background running a beauty consulting firm that worked with brands like Nivea gave him insight into how many people make skincare decisions through expensive trial and error. Oyster aims to shorten that journey, making the kind of analysis once reserved for dermatology offices available to anyone with a smartphone.

Technology that actually sees everyone is technology that works better for all of us.
