Frequently Asked Questions
Is Regio safe for daily use?+
Regio carries a Grade B safety rating and is generally suitable for daily fragrance use. However, as with all fragrances, individual sensitivity varies. If you have reactive or very sensitive skin, apply to clothing or pulse points rather than directly on skin, and discontinue if irritation occurs.
Are there any ingredients I should watch out for?+
The most notable ingredient is Benzyl Salicylate, which makes up approximately 13.7% of the formula. While approved for use in fragrances, people with salicylate sensitivities or aspirin allergies should perform a patch test first. D-Limonene is also present at 12.5% and may cause sensitivity in some individuals.
What does a PSS of 6.6/10 (Grade B) mean?+
The PSS (Product Safety Score) of 6.6/10 with Grade B indicates a moderate safety profile. This means Regio has passed standard fragrance safety testing and is approved for consumer use, but the score reflects that some ingredients warrant attention for people with known sensitivities. Grade B is common for fragrances with spice or citrus notes.
