Frequently asked questions
Does Effaclar Clarifying Solution Acne Toner contain fragrance allergens?
Yes — analysing the INCI list, AllerNote found 1 of the EU-labelled fragrance allergens: benzyl alcohol. If you're fragrance-sensitive or patch-test positive to a fragrance mix, treat Effaclar Clarifying Solution Acne Toner with caution and patch test before full use.
Is Effaclar Clarifying Solution Acne Toner paraben-free?
No parabens were detected in Effaclar Clarifying Solution Acne 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.

It depends on your specific triggers. Effaclar Clarifying Solution Acne Toner contains 1 flagged allergen and 2 irritants (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 Effaclar Clarifying Solution Acne Toner against your own profile.
