About INCI API
We are building the infrastructure layer for cosmetics ingredient intelligence — making safety data transparent, accessible, and actionable for developers and beauty consumers worldwide.
Transparent Beauty Starts with Data
Making cosmetics ingredient data transparent and accessible for developers and beauty consumers worldwide. We believe everyone deserves to know what is in their skincare, makeup, and personal care products — and developers deserve a clean API to build on.
What We Do
Three pillars that power the INCI API platform.
Ingredient Intelligence
We analyze 10,000+ cosmetic ingredients across 20 safety criteria including allergenicity, comedogenicity, irritancy, and pregnancy safety.
Open Data API
RESTful API designed for beauty apps, skincare routines, and e-commerce platforms. Simple integration, comprehensive data, transparent pricing.
Science-Backed
Data sourced from EU CosIng, PubMed, IARC, CIR, and regulatory databases. Every safety score is grounded in published research and regulation.
Trusted, Authoritative Sources
Our ingredient intelligence is built on publicly available, peer-reviewed, and regulatory data sources.
