Frequently Asked Questions
Is Oud 27 Type safe for daily use?+
For most users, yes—the overall PSS Grade B indicates acceptable safety for regular fragrance use. However, patch testing on a small skin area 24–48 hours before full application is recommended, particularly if you have known fragrance allergies or sensitive skin. Those with coumarin sensitivity should avoid or consult a dermatologist first.
Are there any ingredients I should watch out for?+
Coumarin is the primary concern in this formula, rated ISS 4.0/10. It is a naturally derived compound historically flagged for potential allergenicity in some individuals. If you have experienced fragrance-related skin reactions before, pay special attention to this ingredient. The two octahydronaphthalene compounds are rated moderate to solid (6.5–6.6/10) and are widely used in commercial fragrances.
What does a PSS of 6.6/10 (Grade B) mean?+
PSS (Product Safety Score) is an independent safety assessment on a 10-point scale. A Grade B at 6.6/10 indicates the product meets baseline safety thresholds but carries some minor cautions—in this case, primarily the coumarin ingredient. It is not a high-risk product, but neither does it rank in the top safety tier. Individual sensitivity varies, so personal testing remains wise.
