Frequently asked questions
Is Cucumber Herbal Alcohol-Free Toner fragrance-free?
No added fragrance or EU-labelled fragrance allergens were detected in Cucumber Herbal Alcohol-Free Toner's listed ingredients. "Not detected" isn't an absolute guarantee, but it's a good sign for fragrance-sensitive skin — confirm against the current pack and your own triggers.
Is Cucumber Herbal Alcohol-Free Toner paraben-free?
No parabens were detected in Cucumber Herbal Alcohol-Free Toner's listed ingredients. Worth keeping in perspective: parabens are among the least common cosmetic allergens, so "paraben-free" matters far less for reactive skin than avoiding fragrance or the preservative MI/MCI.
Is Cucumber Herbal Alcohol-Free Toner suitable for sensitive or allergy-prone skin?
It depends on your specific triggers. Cucumber Herbal Alcohol-Free Toner contains 1 flagged allergen and 1 irritant (listed in the analysis above). If none are on your personal allergen list it may suit you, but patch test first — add your allergens to AllerNote to check Cucumber Herbal Alcohol-Free Toner against your own profile.
