Slugging is a viral skincare trend where petroleum jelly seals in moisture overnight for dewy, glass-like skin.
The technique gets its quirky name from the shiny, slippery finish resembling a glowing slug.
Slugging works by preventing transepidermal water loss and locking hydration deep into your skin barrier.
This method boosts the effectiveness of hydrating serums applied underneath by sealing them overnight.
People with dry, flaky or compromised skin barriers often see the most noticeable benefits from slugging.
Slugging can be a winter skincare saviour, especially for people living in dry climate areas.
In hot or humid regions, this may feel heavy and increase the risk of clogged pores.
Oily and acne-prone skin types should be cautious, as slugging can trap oil.
Warning: Using strong actives before slugging may cause irritation.
For best results, slugging should be followed with a healthy diet.
