해양심층수 (haeyang simcheungsu) is deep ocean water drawn off Korea's east coast, desalinated and used as the water phase of a product. The minerals are real. Whether swapping purified water for mineral water changes anything you can see on your face is not established, and the marketing runs a long way ahead of the data.

What summer does to your skin

Heat, humidity, sweat and excess oil call for lightweight, fast-absorbing layers and a high, re-applied sunscreen.

How that changes Deep Sea Water

Summer rewards lighter textures and punishes anything occlusive. Strength of active matters less than whether it survives a humid day. Deep Sea Water works on dehydration (water-poor skin), damaged moisture barrier, and it is normally applied BOTH.

What to layer it with

💧 Glycerin💧 Hyaluronic Acid🌾 Beta-Glucan🩹 Panthenol (Pro-B5)
