Frequently asked questions

Is Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide fragrance-free?

No added fragrance or EU-labelled fragrance allergens were detected in Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide'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 Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide paraben-free?

No parabens were detected in Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide'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 Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide suitable for sensitive or allergy-prone skin?

It depends on your specific triggers. Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide 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 Micro-Dose Anti-Aging Retinol Serum with Ceramides and Peptide against your own profile.
