Is 5% Vitamin C Sheer Moisturizer SPF 50 fragrance-free?
No added fragrance or EU-labelled fragrance allergens were detected in 5% Vitamin C Sheer Moisturizer SPF 50'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 5% Vitamin C Sheer Moisturizer SPF 50 paraben-free?
