| Verdict | Italy's gentle introduction to retinol. Collistar's Attivi Puri line uses Hydroxypinacolone Retinoate (HPR) — a retinol ester that doesn't trigger the irritation cycle of classic retinol — paired with panthenol and vitamin E for a buffering effect. Fragrance-free, silicone-free, alcohol-free, and pleasant enough that retinol-anxious skin will actually stick with it. | 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. |
