Slugging
Slugging is the habit of sealing your face with a thick layer of petrolatum-based ointment overnight. It's cheap, a little greasy, and has real logic behind it: occlusives slow water loss from your skin. Whether it helps or backfires depends on your skin type and the rest of your routine. Here's what it does, how to do it, and who should skip it.

Slugging FAQ
What is slugging in skincare?
Slugging means applying a thick occlusive, usually petroleum jelly or an ointment like Aquaphor, as the last step of your night routine. The layer sits on top of your skin and slows water evaporating from it. The name comes from the shiny, slug-trail finish it leaves behind.
Does slugging actually work?
For dry skin or a rough, irritated barrier, the logic holds up. Petrolatum is a well-established occlusive that reduces water loss. But slugging as a trend has little direct research behind it, so most of the support is borrowed from petrolatum studies and dermatologist guidance. It seals moisture in. It doesn't add any, and it won't erase wrinkles.
Can slugging cause breakouts?
It can for some people. Petrolatum itself is generally considered non-comedogenic, but a heavy seal over oily or acne-prone skin, or over products that don't agree with you, may bring on breakouts or small bumps called milia. Evidence is mostly clinical experience and anecdote, so patch test and go slowly.
How often should you slug?
There's no trial-tested schedule. A common approach is to start with two or three nights a week and see how your skin responds. Dry skin may tolerate more nights. If you get new bumps, itching or a greasy-feeling morning face that doesn't clear, scale back.
Can you slug with retinol or tretinoin?
Be careful. Sealing an active under an occlusive may make it feel stronger and increase irritation, though firm data on this is limited. Many people slug on their non-retinol nights, or only once their skin tolerates the active well. If you use prescription tretinoin, ask your prescriber.
