Frequently Asked Questions
Is Acqua Colonia Blood Orange & Basil safe for daily use?+
For most consumers, yes—the product achieves a grade B safety score. However, daily use on sensitive skin or in high concentrations near the face should be approached cautiously. If you experience irritation, itching, or redness, reduce frequency or discontinue. Perform a 24-hour patch test on the inner arm if you have a history of fragrance sensitivities.
Are there any ingredients I should watch out for?+
D-Limonene is the primary concern. This natural citrus compound is a known allergen and skin sensitizer, especially at the 17.5% concentration in this product. If you have citrus allergies or sensitive skin, consult patch testing before regular use. The remaining ingredients (Ambroxan and synthetic musks) carry low-to-moderate ISS scores.
What does a PSS of 6.8/10 (Grade B) mean?+
The Product Safety Score (PSS) is an independent assessment of overall safety based on ingredient profiles and concentrations. A grade B score indicates the product meets acceptable safety standards for fragrance products but contains some ingredients—notably D-Limonene—that warrant awareness, particularly for users with sensitive skin. Grade B products are suitable for general consumers with normal skin tolerance.
