Slugging, the practice of using a thick occlusive (such as petroleum jelly) as the last stage of a nightly routine, has been around for decades, but has recently seen a surge in popularity because of the video sharing platform TikTok.

Damaged, broken, and flaky skin may be repaired by sealing the skin barrier with hydration and avoiding water loss.
However, before you go out and buy a container of Vaseline, Parcells warns that certain people should not use petroleum-based products topically. She warns that “it might wreck major harm on your skin” if done improperly. Instead, Parcells recommends utilizing creams high in ceramides, jojoba oil, and/or squalane to repair the skin barrier and keep water locked in without clogging pores or leaving a greasy residue, even if you have oily, acne-prone, or sensitive skin.
