| Verdict | Icelandic biotech meets skincare. BIOEFFECT grows epidermal growth factor (EGF) in genetically engineered barley plants — a plant-made human-identical growth factor that sidesteps the ethical questions of human-derived alternatives. The clinical data on skin density and wrinkle depth is published and real. Minimal, Scandinavian, and genuinely science-forward in a way most "science" brands aren't. | Frantsila is a small-batch Finnish herbal house that hand-harvests calendula from their own organic farm — and the Calendula Serum is their flagship soothing treatment. Calendula extract anchors the formula, ascorbyl glucoside (a stable vitamin C derivative) brightens, Lactobacillus ferment supports the microbiome, and Finnish birch sap brings traditional Nordic humectant chemistry. Built for reactive, breakout-prone skin. |
