Frequently asked questions

Is The Alpha-Arbutin 2 Discoloration Care Serum fragrance-free?

No added fragrance or EU-labelled fragrance allergens were detected in The Alpha-Arbutin 2 Discoloration Care Serum'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 The Alpha-Arbutin 2 Discoloration Care Serum paraben-free?

No parabens were detected in The Alpha-Arbutin 2 Discoloration Care Serum'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 The Alpha-Arbutin 2 Discoloration Care Serum suitable for sensitive or allergy-prone skin?

It depends on your specific triggers. The Alpha-Arbutin 2 Discoloration Care Serum contains 1 flagged allergen 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 The Alpha-Arbutin 2 Discoloration Care Serum against your own profile.
