There are countless Korean beauty secrets out there – from the 10-step regimen to “cream” skin finishes – but the latest has everything to do with hydration. Introducing: “slugging,” the latest K-beauty trend promising soft, dewy skin.

Just like its counterpart, hair slugging, skin slugging only requires one step. So, what else is there to know about TikTok’s favourite new skin-care step? Keep reading to find out – plus hear from a dermatologist about whether it’s really worth trying.

What is Skin Slugging?

Put simply, slugging is a way to add moisture to the skin and is best used as the last step of your nighttime routine. All you have to do is apply a thin layer of Vaseline or petroleum-based balm all over your face to lock in moisture and seal in your skin-care products. Then, the next morning, you wash it off with your regular face wash and enjoy your newly hydrated, glowing skin.

According to Joshua Zeichner, MD, a dermatologist and associate professor of dermatology at Mount Sinai Hospital in New York City, the first tip to successful slugging is to make sure your face is thoroughly cleansed both before and after applying Vaseline. “If you haven’t removed any dirt, oil, makeup, or other particulate matter from the skin,” he tells POPSUGAR. “It will be trapped underneath, leading to potential irritation or even breakouts.”

Which Skin Types Work Best For Slugging?

If you’re curious to try the trend, there are a few things you should know first depending on your individual skin type. “Slugging is a great option for somebody who has dry skin or irritation,” says Dr. Zeichner. He recommends this method for people who are looking for better hydration, but know that if you’re prone to breakouts or very oily, “covering your face in petroleum jelly overnight may leave you feeling heavy or greasy.”

Who Shouldn’t Try Skin Slugging?

If you’re using potentially irritating skin-care ingredients like retinol, Dr. Zeichner recommends skipping skin slugging altogether. Occluding or locking these products into your skin with petroleum jelly may lead to irritation. Finally, make sure your pillowcase and hair is protected from the slime. He suggests you sleep in a bun or a ponytail and consider wearing a headband to keep the Vaseline on your face and out of your hair.
