| Verdict | Collistar's L-ascorbic + ferulic acid drops — the Italian-pharmacy Skinceuticals C E Ferulic alternative at less than half the price. 15% L-AA + ferulic acid + vitamin E in airless dropper packaging. The Attivi Puri 'drops' format is Collistar's clinical-active line. | 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. |
