Frequently asked questions
Is Retinol 0.5% in Squalane fragrance-free?
No added fragrance or EU-labelled fragrance allergens were detected in Retinol 0.5% in Squalane'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 Retinol 0.5% in Squalane paraben-free?
No parabens were detected in Retinol 0.5% in Squalane'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 Retinol 0.5% in Squalane suitable for sensitive or allergy-prone skin?
It depends on your specific triggers. Retinol 0.5% in Squalane contains 1 flagged allergen and 0 irritants (listed in the analysis above).
