Frequently Asked Questions
Is Midnight Special safe for daily use?+
For most users, yes. The fragrance has a Grade B safety rating. However, daily use should begin with a patch test, particularly on the wrist or inner arm, to check for any individual sensitivity—especially given the higher concentration of Tetramethyl Acetyloctahydronaphthalenes. Discontinue if irritation occurs.
Are there any ingredients I should watch out for?+
The primary consideration is Tetramethyl Acetyloctahydronaphthalenes at 7.5%, which is the dominant ingredient. While it carries a Grade A safety rating, individuals with fragrance sensitivities or very sensitive skin should be cautious. All other main ingredients (Ambroxan, Oxacyclohexadecenone, and Ethylene Brassylate) score well on safety assessments.
What does a PSS of 6.7/10 (Grade B) mean?+
The PSS (Product Safety Score) of 6.7/10 with Grade B indicates that Midnight Special meets acceptable safety standards but carries some moderate considerations—typically related to ingredient concentrations or sensitivities in a subset of users. Grade B fragrances are generally suitable for the general population with standard precautions like patch testing.
