4 experts · Moderate agreementWhat the gurus are saying
This serum's watery, almost-liquid texture makes it exceptionally easy to layer without feeling heavy, and gurus praise it as a reliable alternative to standard hyaluronic acid serums, especially for those who find typical HA sticky or prone to pilling. The marine extracts and algae deliver hydration without the risk of drawing moisture from deeper skin layers the way hyaluronic acid can in dry climates, making it gentler in arid environments. Apply it to damp skin before other moisturizers or serums for best absorption and that plumped, dewy finish.
