So what is slugging, really?
Slugging means putting a thin layer of an occlusive balm, like petroleum jelly, on top of your moisturizer as the very last step at night. The balm sits on the surface and slows down how much water leaves your skin while you sleep. In tests, petrolatum cuts that water loss by more than 98%, and dermatologists already suggest it for dry lips and eyelids. The name comes from the shiny look, not from anything in the jar.
Try it tonight
- Your usual evening steps
Cleanse and moisturize as normal.
- A pea-sized amount of balm
Warm it between your fingertips and press a thin layer onto the driest spots first.
- Pillowcase check
It can feel slippery at first, so a clean pillowcase helps. Fresh surfaces on Today can remind you.
Who might skip it
If your skin runs oily or breaks out easily, a heavy layer can feel like too much, and dermatologists suggest keeping petroleum jelly off acne-prone faces. Stick to dry patches away from breakouts, or skip it. While you’re starting retinol or acids, leave it off those nights, because sealing a strong active in can make it sting.
Common questions
Is it the same as a sleeping mask?
Not quite. A sleeping mask is usually a leave-on gel or cream with ingredients, and slugging is a plain balm layer on top. Both make a good moisture night.
How often?
As often as your skin likes it. Many people keep it to the driest nights of the week.
