What is Slugging?

“Slugging” is a viral skincare trend that essentially involves slathering your face with an occlusive product - like petroleum jelly - to end your nightly skincare routine and seal in moisture to prevent dermal water loss for plumper, more hydrated skin in the morning.

The term "slugging" itself is derived from the shiny finish it leaves on your face - reminiscent of a slug. But, it's better than it sounds. 

So, how does Slugging work? 

Occlusives are a skincare ingredient that sits on top of your skin forming a protective, physical barrier on your skin's surface to prevent moisture loss - otherwise known as transepidermal water loss. They don't actually provide moisture themselves but lock in hydration from other products in your skincare routine. The retained hydration can thicken your skin, making it more pliable and elastic. 

Essentially, occlusives used in slugging create an impermeable wall that seals your skin barrier allowing your skin to remain hydrated while you sleep as well as making any beneficial skincare products you applied leading up to your slugging more potent. Occlusives can also help restore skin lipids and repair your skin barrier. 

Is Slugging for everyone?

Slugging is a better option for those with dry skin and may not be as suitable for acneic or oily skin. The primary ingredient in typical slugging products is petrolatum, which is non-comedogenic, but petroleum based products can trigger breakouts in those more acne-prone. Slugging is also more likely to be helpful in the dry winter months and less necessary in the warmer, more humid months. If you have infections or wounds, it is also recommended to skip slugging as it may not allow the infection to heal. 

How to use Slugging in your skincare routine? 

To use the slugging method in your skincare routine, you just need to apply a small amount of your occlusive at the end of your nighttime skincare routine - this comes after your cleanser, toner, eye cream, serums and moisturizers.  Make sure that your skin is also damp when applying your occlusive and try to avoid active products such as retinol, BHAs and AHAs prior to slugging to avoid sealing in any irritation. 

It is not necessary to completely seal your skin barrier every night, meaning you may want to alternate slugging days with some “non-slug” days. Keep in mind that everyone has different skin with individual skin concerns and needs. If you're wondering if slugging is for you - reach out to your dermatologist for more questions.
