| Verdict | Bioeffect's EGF technology applied to the eye area — and one of the most scientifically distinctive eye treatments available. The EGF (Epidermal Growth Factor) is the brand's hero active: a bioengineered human growth factor protein produced in barley plants via Bioeffect's proprietary ORF Genetics platform in Reykjavik, Iceland. The eye serum delivers EGF in a lightweight gel format calibrated for the thin, delicate skin around the eye, paired with hyaluronic acid for hydration and Trylagen (a complex of peptides and plant extracts for collagen support). The minimalist INCI is intentional — Bioeffect's philosophy is to let the EGF work without interference from unnecessary actives. At ~$90 for 6ml (the eye-area format uses less volume), premium per ml — but EGF-based eye treatments are rare and the Bioeffect platform is the most credible EGF delivery system in consumer skincare. | EcoCert-organic brightening eye cream — Swedish gentle formula with peptides that don't pack a sting. |
