“Slugging” went viral on social media and has since been adopted by skincare enthusiasts worldwide. The technique involves applying a layer of occlusive ointment (typically Vaseline/petrolatum) as the final step in your nighttime routine. But is this trend beneficial, or just another internet fad?
What Is Slugging?
After completing your normal nighttime skincare routine (cleanse, treat, moisturize), you apply a thin layer of an occlusive ointment over your entire face. This creates a physical barrier that traps all the moisture and active ingredients beneath it, preventing transepidermal water loss overnight.
Who Benefits Most
Slugging is most beneficial for people with dry skin, a damaged barrier, or those in harsh winter climates. It’s also useful after using drying treatments like retinol or acne medications, as it helps repair the barrier overnight. People with eczema or severely dehydrated skin often find significant relief from regular slugging.
Who Should Avoid It
Oily and acne-prone skin types should be cautious. Trapping oil and products under an occlusive layer can lead to clogged pores and breakouts. If you have active acne, slugging over inflamed areas can worsen the condition. People using heavy products already may find slugging excessive.
How to Slug Correctly
Use only 100% pure petrolatum, not medicated ointments. Apply a pea-sized amount and gently pat it over your skin rather than rubbing. Use a clean pillowcase, as the ointment can transfer. In the morning, cleanse thoroughly. Start with 1-2 times per week and adjust based on how your skin responds.
