Frequently asked questions

Does Mela B3 Dark Spot Serum With Melasyl+Niacinamide contain fragrance allergens?

Yes — analysing the INCI list, AllerNote found 1 of the EU-labelled fragrance allergens: parfum. If you're fragrance-sensitive or patch-test positive to a fragrance mix, treat Mela B3 Dark Spot Serum With Melasyl+Niacinamide with caution and patch test before full use.

Is Mela B3 Dark Spot Serum With Melasyl+Niacinamide paraben-free?

No parabens were detected in Mela B3 Dark Spot Serum With Melasyl+Niacinamide'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.
