Slugging

Involves coating the skin in some kind of emollient or occlusive (like Aquaphor or Vaseline) as a way of trapping moisture, like a slug or snail, for that beautiful, dewy, slimy look.

If your skin is dry after washing, you might add your hyaluronic acid after a rose water spritz, followed by your night creme, and finish with Vaseline as your 'slug' to trap the moisture.

That’s not what you think it is on my pillow. I tried slugging last night and left a crazy slime trail.
