| 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. | Estelle & Thild's BioHydrate Eye Gel is the Swedish organic brand's most pragmatic product — a lightweight gel that hydrates and depuffs the under-eye area without any of the heaviness that makes richer eye creams impossible in warmer months. Aloe vera juice (the base) provides cooling on contact. Sodium hyaluronate plumps fine dehydration lines. Licorice root extract gently brightens dark circles. Grapefruit extract adds vitamin C and astringent properties. Gluconolactone — a polyhydroxy acid (PHA) — provides the gentlest possible exfoliation, smoother than glycolic acid and less likely to irritate the delicate periorbital skin. Everything organic-certified where possible. This is the eye gel for the person who finds eye creams too heavy and eye serums too watery. |
