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 winter does to your skin

Cold air and indoor heating strip moisture, so layer hydrating toners and essences under a richer cream or occlusive.

How that changes Deep Sea Water

Winter is when barrier support outranks everything. Actives that were comfortable in August frequently are not in January. 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)
