Frequently asked questions
Is Ultra Serum SPF 50+ fragrance-free?
No added fragrance or EU-labelled fragrance allergens were detected in Ultra Serum 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 Ultra Serum SPF 50+ paraben-free?
No parabens were detected in Ultra Serum SPF 50+'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. Ultra Serum SPF 50+ contains 0 flagged allergens and 1 irritant (listed in the analysis above).
