La Mer The Treatment Lotion is a serum-strength watery lotion that delivers visible youth-boosting benefits. Infused with the legendary Miracle Broth, this luxurious treatment lotion floods skin with energy and hydration, leaving it looking plump and radiant. Clinical studies show skin feels 56% more hydrated after just one use, while continued use for 12 weeks results in a 15% reduction in visible redness.

The formula features three key ingredients: Miracle Broth, crafted from sea kelp, vitamins, minerals, and nutrients through a 3 to 4 month fermentation process; The Revival Ferment, an advanced ferment that helps protect skin and resist visible irritation for a calm complexion; and Active Liquid Hydrogel, a proprietary texture from a fermented anti-irritant that cushions on contact and penetrates rapidly for sustained all-day hydration. This treatment lotion is suitable for all skin types and works as a prep step before serums and moisturizers to enhance their effectiveness. Available at Costco as a Member Only item with a limit of 5 per member.
