| Verdict | Premium German biotech anti-aging serum — multi-peptide + retinol + niacinamide, the kind of formula that earns a price tag. | Royal Fern's Phytoactive Serum is the daily-routine entry point to the brand. Lighter than the Anti-Aging Cream but with the same patented fern complex front and center — Osmunda regalis + Dryopteris filix-mas extracts at meaningful position in the INCI, plus sea buckthorn fruit oil + rosehip oil for the omega-rich antioxidant base, two-weight HA for hydration, and bisabolol for soothing. €245 for 30ml — prestige-tier pricing for a serum that genuinely justifies the formulation density. |
