| Verdict | Bioeffect's daytime EGF serum — adapted from the original EGF Serum with the addition of niacinamide and stable vitamin C derivative (sodium ascorbyl phosphate) for daytime antioxidant protection alongside the growth-factor activity. The original EGF Serum is the brand's cult-classic night treatment; the Day Serum extends the EGF platform into daytime skincare with ingredients that complement SPF protection. The hyaluronic acid provides immediate hydration, niacinamide adds barrier support and sebum regulation, and the vitamin C derivative provides antioxidant defence against UV-generated free radicals. At ~$75 for 30ml, premium pricing — but more accessible per ml than the original EGF Serum, and the daytime formulation addresses a genuine gap in most growth-factor skincare routines. | 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. |
