Know exactly what’s in your skincare.

Snap a photo of any ingredient list and get a clear, color-coded breakdown of what everything does — then compare products or check whether your whole routine actually works together. All in seconds, all on your device.

Ingredient labels are written for chemists, not for you. FormuLens translates them. Point your camera at any product, and every ingredient is decoded and sorted by what it actually does — no typing, no searching, no chemistry degree.

Why you’ll love it

• Understand any label in seconds — see what each ingredient does, from humectants and actives to preservatives and fragrance, without looking anything up.
• Shop smarter — FormuLens highlights the ingredients that matter for each product type and flags anything unusual, so you can spot a thoughtful formula before you buy.
• Compare products head-to-head — put two products side by side to see shared and unique ingredients, how the formulas differ, and a plain-language verdict on which fits what.
• Make your routine work together — get the right layering order, catch conflicts between steps, spot redundant overlap, and find the gaps you’re missing.

Three ways to analyze

• Compare — scan several products of the same type and see how they stack up at a glance.
• Check My Routine — scan your routine in order for layering guidance, conflict alerts, overlap notes, and gap analysis.
• Scan Collection — scan any mix of products for a clean, per-product breakdown, no comparison or ordering.

How it works

1. Pick your goal — Compare, Check My Routine, or Scan Collection.
2. Choose your categories — 23 product types across Skincare, Makeup, Hair, Bath & Body, and Fragrance.
3. Snap or import — photograph the label or pick from your library. Long list? Capture it across a few photos and FormuLens merges them into one.
4. Read your results — every ingredient is color-coded by function, key ingredients starred, unusual ones flagged. Sunscreens show their Active and Inactive sections just like the Drug Facts label.
5. Go deeper — tap any ingredient for a plain-language explanation and links to trusted databases (INCIDecoder, COSMILE Europe, EWG Skin Deep).

Keep a library of what you’ve scanned

Save any analysis with a custom name, tags, and notes, then search and filter anytime. Perfect for tracking what worked, comparing across shopping trips, or remembering that one serum you loved.

Made for the ingredient-conscious

Enthusiasts fine-tuning a routine. Sensitive shoppers watching for fragrances or specific actives. K-beauty and J-beauty fans decoding long INCI lists. Parents vetting what goes on their family’s skin. Anyone who’s ever flipped a bottle over and thought, “What is all this?”
