| Verdict | Dermage is the Brazilian derm brand that dermatologists actually prescribe — the kind of brand where formulation decisions are made by PhDs, not marketing teams. Improve C 20 is their 20% pure ascorbic acid serum, and it takes a radically different approach from the water-based vitamin C serums that dominate the global market. The vehicle is anhydrous silicone — cyclomethicone and cyclopentasiloxane form the base, which means the ascorbic acid is suspended in a non-aqueous system where it's inherently more stable than in water. No water = no oxidation pathway = no turning orange in three weeks. The tradeoff is texture: this feels like a silicone primer, not a traditional serum. It glides on with a velvety slip, dries matte, and actually works as a makeup primer — which Brazilian women, who layer SPF religiously in tropical sun, appreciate enormously. The 20% concentration is clinical-grade, matching the gold-standard studies that proved vitamin C's photoprotective benefits. At R$170 (~€35), it's not cheap by Brazilian standards, but for a 20% L-ascorbic acid serum with genuine stability engineering, it's a fraction of what SkinCeuticals charges for the same active. | Sallve's Sérum Antissinais (Anti-Aging Serum) pairs 0.3% retinol with copper tripeptide-1 (GHK-Cu — a peptide with documented collagen-stimulating + wound-healing data) and niacinamide. Copper peptides + retinol in one budget Brazilian serum is genuinely unusual at €23. Fragrance-free formulation. |
