Frequently Asked Questions
Is Irish Leather safe for daily use?+
Irish Leather carries a PSS Grade B rating, meaning it is generally safe for regular use for most consumers. However, because it is an eau de parfum with multiple synthetic ingredients at significant concentrations (up to 10%), daily use on sensitive skin may require caution. A patch test on the inner wrist or behind the ear is recommended before committing to daily wear.
Are there any ingredients I should watch out for?+
The product contains several polycyclic synthetics commonly used in fragrances. While all top ingredients meet acceptable safety grades, individuals with fragrance allergies, asthma, or skin reactivity should review the full ingredient list and consult a dermatologist if concerned. The concentration of ambroxan at 10% is within typical fragrance limits but is worth noting if you have prior sensitivities to musk-type compounds.
What does a PSS of 6.8/10 (Grade B) mean?+
The PSS (Product Safety Score) of 6.8/10 reflects an overall moderate safety assessment based on ingredient profiles, concentrations, and known safety data. Grade B indicates the product is acceptably safe for consumer use but does not rank in the highest safety category (Grade A). This is common for fragrances, which inherently contain multiple synthetic compounds at higher concentrations than other cosmetic types.
