Frequently Asked Questions
Is The Coveted Duchess Rose safe for daily use?+
Yes, for most users. The PSS score of 7.5/10 indicates good overall safety. However, daily application of any eau de parfum should follow normal precautions: apply to pulse points rather than large body areas, and avoid contact with eyes and broken skin. If you have a history of fragrance sensitivity, start with limited use.
Are there any ingredients I should watch out for?+
The two primary ingredients—Tetramethyl Acetyloctahydronaphthalenes and an unresolved polycyclic compound—are synthetic fragrance materials with acceptable safety data. Neither is banned in major cosmetic regulations. If you have sensitive skin or known fragrance allergies, perform a patch test on a small area 24–48 hours before full application.
What does a PSS of 7.5/10 (Grade A-) mean?+
PSS (Product Safety Score) is an independent safety rating where 7.5/10 falls in the 'good' range. Grade A- indicates above-average safety for a fragrance product, with no major regulatory concerns. This score reflects the ingredient profile, concentration levels, and available toxicological data, but does not replace personal skin compatibility testing.
