La Mer The Revitalizing Hydrating Serum is an ultra-lightweight yet powerfully hydrating serum that transforms skin with sea-sourced energy for a radiant, healthy-looking complexion. This soothing, high-speed serum creates a micro-cloud of moisture, flooding skin with nurturing hydration on contact for a look of youthful vitality and glow.

Formulated with La Mer's signature Miracle Broth, a cell-supporting elixir that floods skin with energy, the serum features Deep Hydration Ferment with tiny micro-droplets that absorb rapidly. The Youth Activating Ferment contains ultra-powered marine peptides and key nutrients to support skin's natural renewal. Key ingredients include sea kelp extracts (Undaria Pinnatifida, Ascophyllum Nodosum, Laminaria Digitata), sesame seed oil, alfalfa seed powder, lime tea concentrate, sodium hyaluronate, and acetyl hexapeptide-8 peptides.

Clinical studies show this serum provides visibly revitalized, radiant, glowing skin, infuses skin with more immediate hydration than a humidifier, and energizes and invigorates skin while feeling lightweight, refreshing, and deeply replenishing. Suitable for normal, dry, combination, and oily skin types. Good for dryness, dullness, and uneven texture. Formulated without parabens, phthalates, and sulfates SLS & SLES.
