Why Leoma

Every other app judges a product in isolation. Your skin doesn't.

INCIDecoder, CosDNA, SkinSort: they'll tell you what's in a product. None of them know what's already in your routine. Leoma does. It checks the interactions they ignore: over-exfoliation, pH clashes, actives that cancel each other out. Then it tells you, plainly, whether it fits.

Interactions everyone else misses

  • Benzoyl Peroxide × Retinol
  • Retinol × AHA
  • BHA × Retinol
  • Two exfoliants at once
  • Fragrance × sensitivity

Your routine, built smarter.

Leoma guides you through the five core steps and makes sure every product you add works with everything you already use.

  1. 01

    Cleanser

    AM · PM

    Your reset. Where every routine begins and ends.

  2. 02

    Toner

    AM · PM

    Preps and balances. Where exfoliating acids often hide.

  3. 03

    Serums

    AM · PM

    Where your actives live. And where compatibility matters most.

  4. 04

    Moisturizer

    AM · PM

    Locks everything in. What you put here affects how every layer beneath it performs.

  5. 05

    SPF

    AM only

    Non-negotiable. The last thing on, every single morning.

Every result shows how much to trust it.

Leoma never pretends to be more certain than it is. Every product carries a confidence tier, right where you scan it.
