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.
