Frequently Asked Questions
Is Bois D'hiver safe for daily use?+
Yes, for most adults. The PSS score of 7.2/10 (Grade A-) indicates generally favorable safety when used as directed on skin. However, because it contains 65% Alcohol Denat., apply to pulse points only and avoid excessive application, especially on sensitive or broken skin. Discontinue use if irritation develops.
Are there any ingredients I should watch out for?+
The primary concern is Tetramethyl Acetyloctahydronaphthalenes, a synthetic musk compound rated ISS 6.5/10 (Grade C). This ingredient may trigger sensitivity in individuals with fragrance allergies or reactive skin. Additionally, the high alcohol content (65%) can be drying; people with very dry or compromised skin barriers should use sparingly or consult a dermatologist before regular use.
What does a PSS of 7.2/10 (Grade A-) mean?+
PSS (Product Safety Score) reflects the overall safety profile of Bois D'hiver based on ingredient concentrations and individual safety ratings. A 7.2/10 Grade A- indicates above-average safety with low-to-moderate risk for the general adult population. This grade does not guarantee zero risk; individual reactions vary based on skin type, sensitivities, and usage patterns.
