| Verdict | ISDIN's vitamin C ampoules — and the brand's most considered antioxidant formulation. Each 2ml glass ampoule carries 5% pure L-ascorbic acid + ferulic acid (the Skinceuticals-style antioxidant network) + proteoglycans (sodium chondroitin sulfate and sodium DNA, the Spanish house signature) + hyaluronic acid in a fresh-per-use format that prevents oxidation. The single-dose ampoule format is the key — 5% pure ascorbic acid is famously unstable, and traditional bottle delivery means the product oxidises rapidly after opening; the sealed ampoule keeps it fresh until snap. Use one ampoule per day, applied morning to clean skin before SPF. At $65 for 10x2ml ampoules, premium per ml — but the format genuinely solves the vitamin C oxidation problem. | ISDIN's retinaldehyde powerhouse — a step above retinol in the vitamin A hierarchy. Retinal (retinaldehyde) converts to retinoic acid in one step instead of two, meaning faster results with less irritation than prescription tretinoin. ISDIN pairs it with HPR (hydroxypinacolone retinoate) for a dual-retinoid approach, plus bakuchiol as a botanical synergist and hyaluronic acid for hydration. The Spanish derm brand's most serious anti-aging product. |
