| Verdict | 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. | Santa Maria Novella's Idralia Serum is a stripped-back 13-ingredient HA + carob seed serum. Sodium hyaluronate handles the standard plumping work, Ceratonia Siliqua (carob) seed extract adds a plant-based HA-mimetic for layered hydration, and the rest is buffering and preservation. The minimalist counterpart to the Idralia Cream's fuller formulation. |
