Slugging is the habit of finishing your evening routine with an occlusive layer to help slow water loss while you sleep, so skin feels more comfortable by morning. It is a comfort and moisture-sealing step, not a treatment for any condition, and it is not for everyone — occlusives can feel heavy and may not suit very oily or breakout-prone skin. Below are the Korean product types people reach for when slugging, with honest notes. Apply the occlusive as the last step over a hydrated face, use a clean pillowcase, and patch test anything new.

A classic occlusive that forms a surface seal to slow overnight water loss.
Who it’s for: Dry or compromised-feeling skin; the final slugging layer over a hydrated face.
A rich night cream with ceramides and lipids used as a softer occlusive step.
Who it’s for: Those who find pure petrolatum too heavy but still want a sealing layer.
A leave-on mask designed to sit on skin through the night.
Who it’s for: People wanting a lighter slugging-style finish than a balm.
A plant-derived oil used as a light seal after hydration.
Who it’s for: Combination skin wanting a partial seal without a thick balm.
A plant or wax butter that adds a softening occlusive feel.
Who it’s for: Very dry patches; spot use on cheeks rather than the whole face.
A B5-leaning cream used under the occlusive for a comfortable base.
Who it’s for: Dry, tight-feeling skin building a hydrated layer before sealing.
A humectant layer applied before the seal so there is moisture to lock in.
Who it’s for: Anyone slugging, since an occlusive seals in whatever is underneath.
A short-ingredient occlusive aimed at lower irritation risk.
Who it’s for: Reactive skin that flares with fragrance; patch test regardless.
