slugging

/ˈslʌɡɪŋ/

Common

Applying a thick layer of petroleum jelly as the last step of your nighttime skincare routine to lock in moisture.

Named for the slimy trail a slug leaves. Not suitable for acne-prone skin because the occlusive can trap bacteria.

Use it when

  • Describing the technique of using petroleum jelly as a final skincare step.
  • Recommending or asking about moisture-sealing overnight treatments.
  • Discussing dry skin remedies in a skincare community.

Do not use it when

  • You have acne-prone skin and are recommending it broadly without caveats.

Slugging vs barrier repair

slugging

Slugging is a single technique, applying an occlusive as the final step.

VS

barrier-repair

Barrier repair is a broader goal of restoring the skin's natural protective layer, often involving ceramides, fatty acids, and multiple products.

Origin and context

The term spread widely on TikTok and Reddit skincare communities around 2021-2022, though the technique of using petroleum jelly as an occlusive is much older. The name comes from the visual similarity to a slug's trail.
