Hazel: Acne Trigger Scanner

Wondering if that new foundation is breaking you out? Halo scans the barcode or ingredient label and tells you in seconds - no guesswork, no Reddit deep-dives.

Halo gives every product an Acne Trigger Score based on the ingredients most commonly linked to breakouts in published research. Tap any ingredient to see why it scored the way it did, with sources cited.

— What you can do —

• Scan a barcode for an instant Acne Trigger Score

• Or aim the camera at the ingredient list (no barcode needed)

• See which ingredients are flagged, and why (comedogenic, fungal-acne triggering, hormonal load, common irritant)

• Save products you love and build a history of everything you've tested

— Personalized to your skin —

During onboarding, tell Halo what you're dealing with - hormonal breakouts, fungal acne, cystic acne, or sensitive skin. Halo prioritizes the triggers that matter to you and surfaces them first.

— The database —

Halo's launch catalog includes 300+ curated makeup products, hundreds of skincare items, supplements, and over 250,000 packaged foods. New products added every week. Don't see your product? Scan the label and it'll be added to the community database for the next person.

— Halo Pro —

Free to try. Halo Pro unlocks unlimited scans and full ingredient-by-ingredient breakdowns. Subscriptions start with a 7-day free trial, then $5.99/month or $39.99/year. Auto-renews. Cancel anytime in iOS Settings.

— Important —

The Acne Trigger Score is informational and educational only. It's not medical advice. Skin is personal, and individual reactions vary. For diagnosis or treatment, see a board-certified dermatologist.
