Frequently asked questions
Is 10% Vitamin C Brightening Serum fragrance-free?
No added fragrance or EU-labelled fragrance allergens were detected in 10% Vitamin C Brightening 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 10% Vitamin C Brightening Serum paraben-free?
No parabens were detected in 10% Vitamin C Brightening 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.
