The scoring system for cosmetics analyzes every ingredient that goes into the product.
Based on the current state of science, each ingredient is assigned a risk level according to its potential effects on health or the environment: endocrine disruption, carcinogenic, allergenic, irritant, or pollutant.
Ingredients are classified into four risk categories:
- Risk-free: 75–100
- Low risk: 50–74
- Moderate risk: 25–49
- High risk: 0–24
The score is based on the level of the highest-risk ingredient present in the product.
If a high-risk ingredient is present, the score will automatically be lower than 25/100.
If the highest-risk ingredient is moderate risk, the product’s score will be lower than 50/100.
Yuka's database contains approximately 12,600 cosmetic ingredients. Some may not yet be listed, but they are added after analysis by their toxicologist.
