Frequently asked questions
Is C5 Super Boost Eye Cream fragrance-free?
No added fragrance or EU-labelled fragrance allergens were detected in C5 Super Boost Eye Cream'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 C5 Super Boost Eye Cream paraben-free?
No parabens were detected in C5 Super Boost Eye Cream'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 C5 Super Boost Eye Cream suitable for sensitive or allergy-prone skin?
It depends on your specific triggers. C5 Super Boost Eye Cream contains 2 flagged allergens and 1 irritant (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 C5 Super Boost Eye Cream against your own profile.
