Timing is everything, even more so when it meets your eyes. This overnight treatment contains Ahava's patented Smartium, a technology that allows them to encapsulate the Osmoter, their signature blend of hydrating Dead Sea minerals. These micro-capsules are designed to be sensitive to changes in your skin's pH levels. When pH levels drop during the night, it activates the capsules to release the Osmoter exactly at the right time when the skin is most absorbent. This smart formula helps protect against blue-light damage, lessen the visibility of dark circles and promote eye zone luminosity.
