TikTok is a vast world of beauty and skincare tips.

Slugging, which has gone viral on the app, has roots in South Korea.

Butwhat exactly is slugging, and how can it help your skincare?

By definition, an occlusive is thick and hydrating.

It works by creating a barrier that protects the skin.

Despite its peculiar name, slugging has an array of benefits.

It hydrates, softens the skin, and creates a plump, glowy appearance.

Likewise, slugging is exceptionally affordable; petroleum jelly is less than $10 and is widely available.

In an article forGlamour, Rachel Nussbaum wrote about her experience slugging.

She said, “The difference in my skin was night and day.”

Nussbaum went on to add, “My face has never been so soft.”

Occlusives on their own do not moisturize the skin.

However, when combined with moisturizers, slugging retains hydration.

Dermatologist Sheilagh Maguiness had a similar sentiment.

However, experts warn to avoid products with specific ingredients when slugging.

Dermatologist Orit Markowitz, M.D., toldIpsythat retinoids combined with slugging could worsen skin peeling or flakiness.

A non-skin-related drawback to consider about slugging with petroleum jelly is that it can ruin fabrics.

Moreover, petroleum jelly is not eco-friendly because it is a fossil fuel-based product.
