When I was working on a story about dehydrated skin, I learned about slugging, the K-beauty skincare technique where you apply an occlusive product, like Vaseline or a rich ointment, to your skin
to trap moisture. This is extremely helpful if you're constantly battling dry skin like I am. When I have a bout of dry skin, I do this for a night or two, and my skin feels so much better. And Heather D. Rogers, MD, dermatologist, dermatologic surgeon, and founder of Doctor Rogers Restore, gave me another slugging tip: Before you "slug," dampen your face with water or add a cream (water and oil mixed) for extra hydration since ointments do not contain water.
