| Verdict | BIOEFFECT's intensive treatment — three vials of concentrated barley-derived growth factors (EGF, IL-1A, KGF) for a 30-day skin-renewal protocol at 3x the concentration of the daily serum. Only 9 ingredients. The Icelandic biotech approach distilled to its purest form: no fragrance, no filler, just growth factors at clinical concentrations. The triple growth factor approach targets cellular renewal (EGF), immune support (IL-1A), and keratinocyte growth (KGF) simultaneously. Use every other night for 30 days, 1-4 times per year. | Ecooking's take on vitamin C swaps the harsh L-ascorbic acid common in Korean and American C serums for ascorbyl glucoside — a stable, pH-neutral derivative that converts to active ascorbic acid on contact with skin enzymes. It's a fundamentally Danish approach: less aggressive, more considered, designed to layer under everything without fuss. The aloe-first base (aloe barbadensis leads the INCI, not water) delivers an immediate cooling glide, while sodium hyaluronate and sodium PCA stack two humectants underneath the vitamin C for a hydration-first brightening strategy. Laminaria digitata (kelp) and chlorella vulgaris add marine and freshwater algae antioxidants that the Nordic clean-beauty shelf leans on heavily. At 20ml for ~$42, the per-ml cost is steep, but the formula is fragrance-free, preservative-minimal (sodium levulinate + potassium sorbate), and shelf-stable for 12 months — none of the oxidation anxiety that comes with pure L-AA serums. |
