System Verdict
Decent barrier serum dragged down by low ceramide concentrations, volatile silicones, and irritating essential oils. Efficacy score of 3.6 reflects ceramides listed mid-formula (likely <0.1% each, far below clinical 0.1-1% needed for barrier repair) paired with cholesterol and lecithin for pseudo-lamellar synergy but undermined by evaporative silicones (cyclomethicone, cyclohexasiloxane) that hinder long-term hydration; no pH issues noted but multiple fragrance allergens (bergamot oil, geraniol) risk sensitization without encapsulation. Safety docked to 4.2 for cocktail of 5+ essential oils including potential irritants like patchouli and sage.
