Our Deep Hydration Serum is an intensive lipid restoring spa treatment that helps skin maintain immediate and long term hydration, while also helping skin retain lasting suppleness and comfort. This formula is a unique 2-phase serum, with different ingredients in the gel and in the bubbles. This 2-phase formulation makes it so the serum can fully absorb into the skin, giving you maximum results. We love using this in the colder months for an extra hydration boost and in the summer to rehydrate sun-drenched skin.
