This is a rinse-off overnight mask rather than a leave-on sleeping cream, and that one difference shapes how you use it. You apply a layer as the last step at night, sleep in it, and wash it off with water in the morning — Sulwhasoo specifically suggests skipping cleansing foam on that first rinse so you do not strip away what settled overnight.

The texture is a proper cream, thick enough to sit as a soft film without turning tacky against a pillowcase. A 120ml tube is a lot of product for a mask, so most people use it two or three nights a week rather than nightly, and you can lay it on thicker after a day in the sun or spread it thin as an ordinary last step.

Sulwhasoo builds it on jujube and pomegranate extracts, both of which sit in the ingredient list, alongside the panax ginseng root extract that runs through the whole house range. The richness comes from shea butter and squalane high in the formula, with trehalose, honey and a long tail of Korean botanicals — lotus flower, peony root, rehmannia and licorice root among them.

It is scented, and openly so: fragrance sits in the list along with limonene, linalool, citronellol, citral and geraniol. The herbal scent is part of the experience the brand is selling, but it does mean this is not the mask to reach for if your skin reacts to fragrance.
