Frequently Asked Questions
Is Kuhuyan safe for daily use?+
Kuhuyan meets Grade A- safety standards (PSS 7.0/10), meaning it is generally safe for daily fragrance use by most consumers. However, individual skin sensitivity varies. If you have a history of fragrance allergies or sensitive skin, apply a small amount to the inner wrist or behind the ear first and wait 24 hours to check for irritation.
Are there any ingredients I should watch out for?+
The fragrance contains synthetic polycyclic compounds (hexahydronaphthalenes and acetyloctahydronaphthalenes) that are approved for use in perfumery but may trigger reactions in fragrance-sensitive individuals. AMBROXAN, the primary ingredient at 15%, is well-tolerated but does carry a photosensitivity risk in very high concentrations—this product's level is within safe limits. Patch testing is recommended for sensitive skin.
What does a PSS of 7.0/10 (Grade A-) mean?+
PSS (Product Safety Score) is an independent safety assessment rating. A 7.0/10 Grade A- indicates that Kuhuyan meets high safety standards with only minor considerations, typically relating to individual sensitivity variation rather than widespread health concerns. This grade suggests the product is appropriate for general consumer use when applied as directed.
