Built with care
Each product gets a score from 1–10 derived from peer-reviewed studies, IARC classifications, and regulatory bans across 20+ jurisdictions. No opinions — only citable sources.
Tell us your conditions and sensitivities once. clarvn applies condition-specific ingredient modifiers so the score reflects your body, not just an average.
When a product scores Caution or Avoid, clarvn surfaces real, widely-available alternatives with lower ingredient concern profiles.
Your health profile is stored only on your device. It never leaves your browser. clarvn computes your personal score locally — no server ever sees your conditions.
How scores are calculated
Every score is computed from three weighted dimensions: harm evidence (40%), regulatory consensus across 20+ jurisdictions (35%), and avoidance priority (25%). All citations are traceable to published studies or official regulatory actions. Scores are AI-generated and reviewed periodically — they are not a substitute for medical advice.
