| 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. | Mantle's The Retinol Serum is the Swedish CBD-skincare brand's evening retinoid platform. Retinol paired with bakuchiol (the retinol alternative) for synergistic anti-aging work, plus Cannabis Sativa seed oil + leaf extract for the brand's signature CBD anti-inflammatory positioning, niacinamide + sodium hyaluronate buffering, sea buckthorn fruit extract for additional antioxidant work, and beta-sitosterol/phospholipids for membrane-mimetic delivery. €68 for an unusual CBD + retinol + bakuchiol triple-pathway formulation. |
