| 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 hyperpigmentation specialist — and the product Italian dermatologists reach for when prescribing a topical depigmentation protocol for melasma, post-inflammatory hyperpigmentation, and sun spots. The triple-active approach is pharmacologically sound: tranexamic acid inhibits plasminogen activation (blocking UV-triggered melanogenesis at its earliest signal), niacinamide prevents melanin transfer from melanocytes to keratinocytes (reducing visible pigmentation even if melanin is still produced), and ascorbyl glucoside (stable vitamin C) provides antioxidant tyrosinase inhibition. Three mechanisms, three targets, one product. At ~€34 (~$38) for 30ml, it dramatically undercuts comparable multi-active brightening serums from international brands. The dropper format delivers concentrated liquid drops — thin, fast-absorbing, layerable under moisturizer and sunscreen. Fragrance-free, dermatologist-tested, suitable for sensitive skin. This is the product Rilastil was made to create. |
