Slugging for Dry Skin: Benefits, Risks, and How to Do It
Slugging means applying a thin layer of an occlusive ointment over moisturizer, usually at night, to reduce water loss. It can help very dry areas feel softer, but it is not necessary for everyone and it does not “detox,” exfoliate, or permanently repair skin.
How slugging works
Occlusive ingredients form a surface layer that slows evaporation. They do not add water by themselves, which is why slugging is usually done after a moisturizer or on slightly damp skin.
A simple slugging routine
- Cleanse gently and pat skin mostly dry.
- Apply any non-irritating hydrating serum if desired.
- Apply moisturizer.
- Spread a very thin layer of a plain occlusive ointment over the driest areas.
- Wash gently in the morning if residue remains.
Who may benefit?
People with dry, flaky, or seasonally dehydrated skin may find occasional slugging comfortable. It can also be useful on small dry areas rather than the entire face.
Who should be cautious?
- People who dislike heavy textures or tend to develop clogged pores
- Anyone with an active rash, infection, or weeping skin
- People using strong exfoliants or prescription treatments underneath
- Anyone with known allergy to an ingredient in the ointment
Occlusion can increase the effect—and irritation—of certain ingredients. Do not seal strong treatments under an ointment unless your clinician or the product directions say it is appropriate.
Is petroleum jelly “clean beauty”?
“Clean beauty” has no single regulated definition. Evaluate the safety, purity, function, and transparency of the finished product rather than assuming an ingredient is good or bad because of a marketing category. Properly refined petrolatum is widely used as an occlusive in skincare.
Alternatives to full-face slugging
Try a richer cream, add a humidifier in dry weather, use a fragrance-free cleanser, shorten hot showers, or apply an occlusive only around the lips and other dry patches.
