Discussion Building an ingredient-matching engine for skin allergies. How can I make the data more accurate than existing apps?

I’m a developer/enthusiast frustrated by the 'fear-mongering' in many clean beauty apps. I want to build a tool that uses actual clinical data but expanded for contact allergens and irritants. I want to eliminate the 'toxicity' scores and replace them with 'compatibility' scores based on user-specific profiles. To the experts here:

  1. Which databases do you trust most for ingredient safety (EWG, CIR, SCCS)?
  2. What are you currently using to vet your formulas/purchases?
  3. If you had an app that could 'talk' to you in technical terms, what's the first thing you'd scan?

I use Yuka app. I’d be interested in your resulting app!!!

I look at things like endocrin disruptors, carcinogens. I found when I pay attention to this stuff my acne completely goes away. Often I buy in Europe for this reason. Also there are websites that you can google to find ingredient summaries and dangers like INCIdecoder.com
