Step 4: Treatment
Targeted actives — serums, ampoules, and treatments for specific concerns.
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.

Bioeffect's EGF Serum is the cult Icelandic skincare product that built an entire biotech category. Founder Dr. Björn Örvar engineered barley plants — grown in volcanic pumice in geothermal greenhouses — to produce human EGF (epidermal growth factor). The result is the cleanest, most-stable, plant-derived growth factor on the market, and a brand that's quietly become the prestige skincare reference point.
