| Verdict | ISDIN Night Peel is the product that proves the ampoule format works as brilliantly for exfoliation as it does for antioxidants. Each sealed glass ampoule contains a precise dose of multi-acid exfoliant — glycolic acid (AHA for surface-cell turnover), malic acid (gentler AHA for sensitive-skin compatibility), tartaric acid (antioxidant AHA from grape), and citric acid (pH-adjusting, mild exfoliant) — buffered with glycerin, sodium lactate, and saccharide isomerate (a biomimetic moisturiser that binds to the skin's surface for hours). The ampoule format solves the stability problem that plagues AHA products in open bottles: each dose is factory-sealed, never exposed to air or light, and delivers the acids at their intended concentration and pH every single time. No oxidation. No degradation. No guessing whether the product still works three months after opening. The instructions are simple: snap the ampoule, apply to clean face, sleep. The acids work overnight at a controlled pace — not fast enough to irritate, fast enough to smooth texture, even tone, refine pores, and reduce fine lines over 4-6 weeks of consistent use. This is pharmaceutical-grade resurfacing delivered in a format invented by a Barcelona pharmacy. The 10-ampoule box is a 10-night treatment course. The results accumulate. The ritual is addictive. | MartiDerm's iconic nighttime exfoliating ampoules — formerly sold as 'Alfa Peeling' and rebranded to Platinum Night Renew with the same proven formula. The AHA cocktail runs five acids (10% total: glycolic, lactic, malic, tartaric, citric) — a poly-hydroxy approach that exfoliates at multiple depths. Glycolic (smallest molecule) drives the deepest penetration; lactic provides gentler surface exfoliation with built-in humectancy; the fruit acids (malic, tartaric, citric) fill the mid-range. Soluble collagen and sodium hyaluronate provide immediate plumping, while sodium DNA supports cellular repair. The single-dose ampoule format is MartiDerm's signature — no preservative degradation, precise dosing, and the ritual of snapping open a fresh vial each night. At ~$50 for 30 ampoules (a month's supply), the per-use cost is about $1.67 — excellent value for a clinical-grade nighttime peel. A pharmacy-counter classic in Spain since the late 1990s. |
