About sukashi
Concept
sukashi (透かし, meaning 'transparency') is a tool that discovers similar cosmetics based on their full ingredient lists. Find affordable alternatives that share similar ingredient profiles with premium products.
How It Works
We collect full ingredient lists from official manufacturer websites and normalize them to INCI (International Nomenclature of Cosmetic Ingredients) standard names. Similarity is calculated using Overlap Coefficient, with position-weighted scoring that accounts for ingredient concentration order.
Data
