| Verdict | Collistar's Pure Actives Niacinamide + Zinc serum is the brand's Italian answer to The Ordinary's cult niacinamide formula. 10% niacinamide + zinc PCA + sodium hyaluronate + panthenol + allantoin in a 17-ingredient fragrance-free formulation. €40 for stripped-back actives at Italian pharmacy pricing. | Miamo's hero product and the reason the brand matters. 30% 3-O-Ethyl Ascorbic Acid — a stable, bioavailable vitamin C derivative that doesn't oxidise in the bottle like pure L-Ascorbic Acid — plus ferulic acid for antioxidant synergy and sodium hyaluronate for hydration. Founded by two pharmacists who trained in the US and brought cosmeceutical rigour back to Naples. The concentration is genuinely high, the stability is genuinely better than most LAA serums, and the €94 price tag is fair for what's in the bottle. |
