Quick answer: SafeShelf is the best free AI ingredient checker for food, cosmetics, and supplements with no scan limits. EWG Skin Deep is the most comprehensive cosmetics database. Yuka requires a paid subscription after 40 free scans. INCI Decoder is cosmetics-only.

If you've searched for a way to check what's in your food or beauty products, you've probably encountered at least one of these four tools. They all help consumers understand ingredient labels — but they work in fundamentally different ways, cover different product types, and have very different price points.

This guide compares them honestly across the dimensions that matter most: product coverage, how they work, accuracy, personalisation, and cost.

When to Use Each Tool

Use SafeShelf when:

  • You want to scan any product — food, cosmetics, supplements, household cleaners, baby products, or pet food — from a single tool
  • The product isn't in a barcode database (new releases, international products, small brands, farmers market items)
  • You want personalised analysis based on your medications, allergies, pregnancy, or dietary restrictions
  • You need drug interaction warnings (e.g. Warfarin + Vitamin K, SSRIs + St. John's Wort)
  • You want unlimited free scans with no paywall

Use EWG Skin Deep when:

  • You're researching a specific named cosmetic product from a major brand with years of documented safety data
  • You want deep regulatory history on a specific ingredient across decades of research
  • You prefer a manual database approach over AI

Use Yuka when:

  • You're shopping in a supermarket and want a quick barcode scan
  • The product is from a major brand already in Yuka's database
  • You don't mind the 40-scan free limit or paying for premium

Use INCI Decoder when:

  • You want to look up individual cosmetic ingredients by INCI name
  • You're a formulator or skincare enthusiast doing deep ingredient research

The Bottom Line

No single tool is perfect for every use case. For most consumers wanting a fast, free, and comprehensive check of any product they encounter — especially one that works without barcodes and covers food, cosmetics, and supplements — SafeShelf is the strongest all-round option in 2026. For deep cosmetic database research on major named brands, EWG Skin Deep remains the gold standard.
