- Children — Higher risk of mascara transfer to eyes and ingestion; developing immune system more reactive to sensitizers; higher inhalation exposure due to proximity to face
- Individuals With Fragrance Sensitivity Or Asthma — Inhalation of volatile fragrance and solvent components can trigger respiratory reactions
