Slugging': The K-Beauty Secret for Insanely Hydrated Skin
Imagine going to bed and waking up with skin that feels as soft, plump, and hydrated as a baby’s. That’s the promise of "slugging," a simple, low-cost K-Beauty hack that has gone viral for its incredible effectiveness, especially for those with dry or dehydrated skin.
The name might sound a little strange, but the science behind it is solid. So, what exactly is slugging, and should you be doing it?
What is Slugging?
Slugging is the practice of applying a thin layer of an occlusive product—most commonly a petroleum-jelly-based ointment like Vaseline, Aquaphor, or CeraVe Healing Ointment—as the very last step of your nighttime skincare routine.
The term "slugging" comes from the shiny, slimy appearance your face has after application, much like a slug trail. It might not sound glamorous, but the results can be.
The Science: How Does It Work?
The magic of slugging lies in the power of occlusion.
Throughout the night, your skin loses water to the surrounding air in a process called Transepidermal Water Loss (TEWL). An occlusive product creates a physical barrier on top of your skin, acting like a shield. This shield dramatically reduces TEWL, effectively locking in not only your skin's own moisture but also all the beneficial ingredients from the serums and moisturizers you applied beforehand.
Think of it like putting a lid on a pot of water. Without the lid, the water evaporates. With the lid, it stays put. Slugging is the "lid" for your face. It’s a cornerstone of a good recovery routine, especially when you're doing Skin Cycling: The 'Less is More' Trend That Actually Works.
Who Should (and Shouldn't) Try Slugging?
Who it's for:
- Dry or Dehydrated Skin: This is a game-changer. It provides immense relief and visible plumping overnight.
- Compromised Skin Barrier: If your skin is feeling irritated, red, or sensitive from over-exfoliation or harsh weather, slugging can help repair the barrier quickly.
- Mature Skin: As we age, our skin produces less oil and has a harder time retaining moisture. Slugging can restore that youthful bounce.
Who should be cautious:
- Acne-Prone or Oily Skin: This is the main caveat. While petroleum jelly itself is non-comedogenic (meaning it doesn't clog pores), it can trap oils, dead skin cells, and bacteria that do. If you are very oily or actively breaking out, it's best to avoid slugging or to patch-test on a small area first.
How to Slug, The Right Way
- Complete your full PM routine: Cleanse, apply your hydrating serums (like Hyaluronic Acid) and your regular moisturizer.
- Wait a few minutes: Let your products absorb slightly.
- Apply a pea-sized amount: You don't need to goop it on. A thin, even layer is all you need. Warm a small amount between your fingertips and gently press it onto your skin.
- Go to sleep: Protect your pillowcase with a towel and let the magic happen.
- Cleanse in the morning: Wash your face as usual in the AM to remove the occlusive layer.
Slugging is proof that effective skincare doesn't have to be expensive. It’s a simple, powerful technique to supercharge your hydration, repair your skin barrier, and wake up to a complexion that is visibly plumper and glowing with health.
