| 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. | Rilastil's Multirepair HA Serum is an unusual hybrid: hyaluronic acid serum + low-grade mandelic AHA in one formulation. Mandelic acid is the gentlest of the AHAs (largest molecule = slower penetration = less irritation), pairs surprisingly well with hydrolyzed HA + sodium butyroyl hyaluronate (a deep-penetrating HA derivative) for layered hydration with mild exfoliation. €50 for a clinical hybrid you'd otherwise have to layer two products to get. |
