Frequently asked questions
Is 20% Vitamin C Face Serum fragrance-free?
No added fragrance or EU-labelled fragrance allergens were detected in 20% Vitamin C Face Serum'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 20% Vitamin C Face Serum paraben-free?
No parabens were detected in 20% Vitamin C Face Serum'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 20% Vitamin C Face Serum suitable for sensitive or allergy-prone skin?
No commonly-flagged allergens or irritants were detected in 20% Vitamin C Face Serum, which is encouraging for reactive skin — but "no known flags" isn't the same as "safe for everyone." Patch test before full use, and check it against your own allergen profile on AllerNote.
