What Is Slugging Skincare & How To Do It

If you’ve been anywhere near the skincare side of the internet, you’ve probably heard of slugging skincare—the viral beauty trend that promises ultra-hydrated, glowing skin. Originally popularized by K-beauty, slugging involves coating your skin with an occlusive layer, like petroleum jelly, to lock in moisture overnight. The result? A plumper, dewier complexion by morning.

But while slugging skincare can be a game-changer for dry or compromised skin, it’s not for everyone. In this guide, we’ll break down exactly how to do it, who should avoid it, and what to use instead if slugging isn’t the best fit for your routine. 

What Is Slugging Skincare? 

Slugging is the practice of applying an occlusive layer as the final step in your nighttime routine to prevent moisture loss and strengthen the skin barrier. 

This method is especially beneficial for those with dry, dehydrated, or compromised skin, as it helps lock in hydration and enhances the effects of your skincare products.

Here’s How Slugging Works

Originating from K-beauty, slugging skincare has gained massive popularity thanks to its dramatic, dewy results—and its undeniable glisten. The trend exploded on social media as people shared videos of their faces coated in a thick, glossy layer of occlusive moisturizer.

But beyond its viral appeal, slugging is rooted in serious skincare benefits. 

Throughout the day, environmental factors like cold weather, indoor heating, and even over-cleansing can strip your skin of essential moisture. By applying an occlusive as the final step in your routine, slugging creates a protective seal that locks in hydration and helps repair the skin barrier overnight.

Popular Occlusives for Slugging

While petroleum jelly (Vaseline) is the most well-known slugging occlusive, there are several other options that can achieve similar benefits, some with added skincare perks:

• Lanolin – A natural wax derived from sheep’s wool, lanolin is highly effective at sealing in moisture while also being slightly more breathable than petroleum jelly. (Aquaphor contains both lanolin and petroleum jelly.)
• Squalane – A lightweight, non-greasy occlusive that mimics the skin’s natural oils, making it ideal for those who find petroleum-based products too heavy.
• Shea Butter – A rich, plant-based occlusive that not only locks in moisture but also nourishes the skin with vitamins and fatty acids.
• Mineral Oil – A dermatologist-approved occlusive that’s hypoallergenic and great for preventing moisture loss without clogging pores.

Each of these occlusives can be used for slugging depending on your skin’s needs and preferences. The key is to find one that works for your skin type and pairs well with your routine.

Now we’ll walk through how to properly slug your skin for maximum hydration—without making a greasy mess.

How To Do Slugging Skincare (Step-by-Step)

Slugging is simple, but doing it the right way ensures you get the benefits without feeling overly greasy. Here’s how to do it:

1. Start with a Clean Face – Use a gentle cleanser to remove dirt, oil, and makeup.
2. Apply Hydrating Layers – Use a lightweight toner, essence, or moisturizer to prep your skin.
3. Slug It – Apply a thin layer of your chosen occlusive (like petroleum jelly, squalane, or lanolin) over your face and neck.
4. Let It Work Overnight – Sleep with the occlusive on, and wake up with deeply hydrated skin.
5. Rinse Off in the Morning – Cleanse your skin gently to remove any excess product before continuing with your normal routine.

For best results, slugging works well a few times a week, especially during colder months or whenever your skin needs extra moisture.

Who Should Avoid Slugging?

While slugging can work wonders for some, it’s definitely not for everyone. 

Here are a few skin types and situations where you might want to skip slugging skincare routines:

• Oily or Acne-Prone Skin: If your skin is already producing excess oil or prone to breakouts, slugging could make things worse by trapping oil, dirt, and bacteria. The occlusive layer can clog pores and lead to increased acne or congestion.
• Sensitive Skin: If you have sensitive skin or conditions like rosacea or eczema, the thick layer of occlusives could cause irritation or exacerbate redness. It’s best to avoid slugging if your skin is easily irritated.
• Active Skincare Users: If your routine includes strong actives like Strut’s tretinoin cream, or benzoyl peroxide, or AHAs, it’s best not to combine them with slugging on the same night. The occlusive layer can intensify the effects of these powerful ingredients, leading to irritation or peeling. However, you can still slug on your off nights, alternating between using actives and sealing in moisture with an occlusive. This way, you can enjoy the benefits of both without overwhelming your skin.

Takeaway Tips for the Perfect Slugging Routine

If you decide to try slugging skincare, here are a few tips to make sure you're getting the most out of this technique:

• Frequency: Slugging isn’t something you need to do every night. For most people, 2-3 times a week is enough to see a difference in hydration and skin barrier strength.
• Products to Use: Stick to lightweight, hydrating serums or creams before applying your occlusive layer. Avoid anything too thick or heavy underneath the occlusive, as it can feel overwhelming and cause congestion.
• Patch Test: If you're new to slugging or using a new occlusive, patch test on a small area of your skin first to check for irritation or sensitivity.
• Morning Routine: Don’t forget to cleanse your face in the morning to remove any residual product and prevent buildup. Follow up with your usual daytime skincare routine.

Is Slugging Right for You?

Slugging skincare is a fantastic option for those looking to restore moisture, heal a compromised skin barrier, or simply enjoy a dewy glow. However, it’s not a one-size-fits-all solution. If you have oily skin or use strong actives like tretinoin, slugging might not be the best fit for your routine.

If you’re looking for deep hydration without the occlusive layer, consider adding hydrating, barrier-repairing creams or serums into your routine.
