| 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. | Mesoestetic's professional-grade brightening peel — and the at-home extension of the brand's clinical depigmentation protocols. The dual-acid approach pairs 10% glycolic acid (deep exfoliation, collagen stimulation) with 2% phytic acid (an antioxidant acid derived from rice that inhibits melanin transfer — making it specifically effective against hyperpigmentation rather than just general exfoliation). Centella Asiatica provides anti-inflammatory support to counterbalance the acid irritation potential. At ~$57 for 50ml, it's positioned between pharmacy peels and dermatologist treatments — stronger than The Ordinary's glycolic toner but gentler than an in-office peel. The clear gel format makes application precise — apply to clean, dry skin at night, avoid the eye area. For hyperpigmentation specifically (melasma, PIH, sun spots), this is one of the most targeted OTC options from any Spanish brand. Pairs naturally with mesoestetic's Cosmelan protocol for a complete depigmentation strategy. |
