| 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. | 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. |
