| Verdict | MartiDerm's most iconic ampoule — and the Spanish 'before-the-event' beauty ritual in glass-vial form. Each 2ml nitrogen-flushed ampoule carries 5% pure L-ascorbic acid + dual-weight hyaluronic acid (sodium hyaluronate + hydrolyzed) + ferulic acid + proteoglycans (sodium chondroitin sulfate, sodium DNA — MartiDerm's house actives) + Argireline peptide. The nitrogen-flushed glass keeps the vitamin C stable at full clinical potency until the moment you snap the ampoule. The ritual of snapping a glass vial, dispensing the entire 2ml dose, applying directly to clean skin, is part of why MartiDerm is the brand Spanish women reach for the night before a wedding, a job interview, or a photographed event. At $55 for 30 ampoules (~$1.80 each), mid-tier per dose — but a fresh, oxidation-free 5% L-AA hit that bottle-format serums genuinely cannot match. | Segle Clinical's vitamin C serum — and the reason Spanish pharmacists reach for this brand when customers ask for brightening. The formulation uses ethyl ascorbic acid (5%) instead of L-ascorbic acid, a deliberate choice: it's more stable (no oxidation within weeks of opening), penetrates well, and converts to active ascorbic acid in the skin. The supporting cast is smart — hyaluronic acid for hydration, panthenol for barrier support, and Chlorella vulgaris extract (the brand's signature marine plankton ingredient) as an anti-stress antioxidant. At ~$33 for 30ml, it undercuts comparable stable-C serums from international brands by 50–70%. The texture is genuinely light — a watery liquid that absorbs in seconds without residue, layering cleanly under sunscreen. Not the most potent vitamin C on the market (La Roche-Posay Pure Vitamin C10 or SkinCeuticals C E Ferulic deliver higher concentrations), but the stability advantage means you're actually getting the stated percentage throughout the bottle's life. |
