In the world of skincare, “slugging” has become a buzzword with roots in K-beauty and a growing fanbase worldwide. This nighttime routine involves applying an occlusive layer—most commonly petroleum jelly—over your moisturizer to lock in hydration. While it might sound unconventional, dermatologists and skincare enthusiasts alike are praising slugging for its ability to restore the skin barrier, especially for those dealing with dryness, irritation, or compromised skin.
The key to slugging’s success lies in its simplicity and science-backed mechanism. Occlusives like petrolatum form a protective barrier that prevents trans-epidermal water loss (TEWL), allowing the underlying skincare ingredients to work more effectively overnight. However, experts advise using this method sparingly and ensuring the skin is properly cleansed and hydrated before sealing it in—particularly for acne-prone skin types.
Slugging isn’t a one-size-fits-all solution, but when used correctly, it can dramatically improve skin texture and moisture retention. As with any trend, it’s essential to understand your skin’s needs, patch test, and consult a dermatologist if unsure. In a market flooded with complex routines, slugging offers a minimal, cost-effective way to support healthy, dewy skin—especially during colder, drier months.
