Skincare Slugging Explained: Benefits, How-To & Best Products

If you’ve spent any time scrolling through skincare TikTok or beauty-related subreddits, chances are you’ve come across the word slugging. The technique has gained cult status among skincare enthusiasts, praised for its potential to revive dry and tired-looking skin.

In this guide, we’ll explore how the slugging skincare trend works, which skin types can benefit most from it and how to introduce it into your routine.

What is skincare slugging?

Despite the name, it has nothing to do with snails and everything to do with moisture. Slugging is a skincare technique built around one simple goal: boosting hydration.

By adding it to the end of your nighttime routine, slugging helps seal in moisture and strengthen the skin’s barrier while you sleep. For some, it’s the secret to waking up with soft, supple, glass-like skin.

Best products for slugging

When it comes to slugging, the key is choosing an occlusive balm or ointment. Most people reach for a simple petroleum jelly formulated to minimise moisture loss. If you prefer something lighter, look for ointments that blend petrolatum with emollients such as squalane or ceramides. These additions help soften the texture and create a more flexible, velvety finish while still encouraging deep overnight hydration.

Benefits of slugging in skincare

Here are other ways slugging skincare can be good for your skin:

• Supports skin barrier function

When the skin’s barrier becomes compromised, it’s more vulnerable to dryness, irritation and environmental aggressors. Slugging helps reinforce this barrier by creating a physical layer that locks in hydration and shields against external stressors. Over time, this can lead to healthier, more resilient skin.

• Provides soothing and comforting relief

Slugging can also provide a sense of relief for dry or irritated skin. The occlusive layer cushions the skin and reduces contact with potential irritants in the environment, creating an ideal setting for overnight skin comfort and renewal.

• Enhances product absorption

When performed after your hydrating steps, skincare slugging can help hold in the benefits of serums and moisturisers. This gentle “locking in” effect allows active ingredients, such as antioxidants and vitamins, to remain in closer contact with the skin for longer, optimising their performance.

Best skin types for slugging: who should try it (and who shouldn’t)

Slugging is best suited to dry, mature or compromised skin that struggles to retain moisture. It can also be especially helpful during cold or low-humidity seasons, when the air tends to draw moisture out of the skin.

However, slugging skincare for acne-prone skin is generally not advised. Because this method relies on rich, occlusive products, it can trap oil, sweat and debris within the pores, which may contribute to congestion or increased breakouts.

Likewise, slugging skincare for oily skin may feel too heavy or uncomfortable. Petrolatum’s thick texture can create a surface environment that intensifies greasiness rather than offering relief.

How to do slug skincare

Want to try slugging for yourself? Here’s how to approach it with care and intention.

1. Start with a clean base

Begin by cleansing your face thoroughly to sweep away makeup, SPF and daily build-up. You don’t want to trap in impurities, so this step is essential for a fresh, clean canvas.

2. Layer your hydration

Next, reach for your toners or serums that contain ingredients like hyaluronic acid, ceramides or peptides. If you have sensitive skin, skip potent actives such as retinoids or acids on slugging nights because the occlusive layer can make them too intense.

3. Add moisture

Follow with a nourishing night cream or moisturiser. This helps cushion the skin and adds an extra hit of hydration before the final step.

4. Seal it in

Now comes the “slug”. Apply a thin, even layer of an occlusive balm or ointment. Focus on drier areas if your skin doesn’t need a full-face treatment.  

5. Let your skin rest

Leave the layer on overnight and let it work its quiet magic. In the morning, cleanse gently to remove any residue, then continue with your usual morning routine.

Pro tip: You don’t need to slug every night. For most skin types, once or twice a week is enough to keep skin strong, dewy and glowing.

Where else can you do slugging?

You might be surprised to know that slugging isn’t limited to the face. Many people extend the technique to areas prone to persistent dryness, such as the hands, elbows, knees and feet. After showering, apply your usual body moisturiser and then follow with occlusive balm. Some also use slugging on the neck, chest or around the cuticles to keep these delicate areas feeling soft and protected. 

And for those dealing with very dry feet in winter, applying an ointment after moisturising and slipping on a pair of socks before bed can create an intensely nourishing “foot slug” that works while you sleep.
