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
