| 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. | Fragrance-free BioCalm serum with beta-glucan and centella. Sensitive-skin mainstay of Scandinavian pharmacies. |
