Tiktoker and Reddit swear by it to give a baby like smooth skin and a shine that makes your haters ask for a pair of sunglasses — they call it slugging!

So, what exactly is slugging?

Slugging is the process of generously applying a petroleum-based product ( like Vaseline or Cerave Healing Ointment ) as the final step in your routine, to help lock and seal in your skincare products overnight, and then washing it off with a cleanser the next day. So, all those serums you applied? They’re not going anywhere.
Slugging is a great skincare technique in the wintertime or in Nigerian harmattan weather for those with dry or sensitive skin because Petroleum jelly is an occlusive ( a moisturizing agent that creates a physical barrier on the skin to lock in hydration and prevent water loss) that is not only amazing at soothing irritated skin and promoting wound healing, but it can also act as a protective barrier for the skin against water loss.
Does slugging truly work?
Yes, slugging actually works when done right and the benefits are kind of incredible.
Plump, glowing skin may seem like an impossible feat, particularly if you typically have dry or very dry skin. But if you suffer from dry harmattan skin or flakiness and want something to tackle the dry stiff feeling on your skin, slugging might be the secret weapon to that glazed donut skin you've been looking for.

What are the benefits of slugging?

Moisturizes: “The retained hydration can fill the epidermis like a sponge, thickening it and making it more pliable and elastic.
Protects: That barrier from applying petroleum-based products ( like Vaseline or Cerave Healing Ointment ) keeps water in — and keeps the bad stuff out. “It can help prevent outside molecules from entering the skin and causing irritation.
Repairs damage: If you are dealing with flakiness, cracked feet or your skin is dehydrated, a coating of petroleum jelly at night can help prevent further water loss from the skin and allow it to repair itself.

Who is it good for?

Slugging is a bit intense, so it's best for those with super-dry skin or a compromised skin barrier (think sensitive skin conditions). For these skin types, sealing in hydration is crucial; water can easily seep out of an already leaky skin barrier, after all. "Slugging could prevent that water loss from happening, helping your skin kick-start the process of repairing your skin barrier," say experts.
Of course, slugging is not for everybody—and even if it works for you, you might not want to "slug" on the daily. But if you have oily or acne-prone skin, you especially might want to steer clear.

How to slug.

Due to the thick texture of Petroleum jelly, it is advisable to slug at night before bed when the sun is not out. In addition to that, your skin works hardest to repair itself while you sleep, so slugging right before bed is the preferred and most popular method.

Step 1: Do your normal skincare routine, but omit any spot treatments or face oils
Step 2: While your skin is still slightly damp from products, spread a pea-size scoop of Vaseline over your skin. You don’t need a thick layer—as long as you’re covered, you’re slugging.
Step 3: In the morning, cleanse your skin to remove any excess Vaseline (use an oil cleanser if necessary).

How often should you slug?

Experts say that this really depends on your individual skin type and personal preferences. "If you have very dry skin and need an extra boost during the winter time, you can slug as often as you’d like,"


Slugging involves layering an occlusive product on your skin to seal in moisture. It’s usually done as the last step in a nightly skincare routine.
Those with oily or acne-prone skin may want to skip it, but those who have dry skin or very dry skin in harsh harmattan weather may significantly benefit from it. If you’re not sure whether it’s right for you, talk with an expert or your dermatologist.
