Part of the post’s Thai-language caption translates to English as: “#NewDimensionofApplyonAcne I heard that toothpaste can deflate acne, so we tried it on our model. The result is acne has reduced in size. Like obviously, just applying the toothpaste on acne.”

The post was published alongside four photos: the first is a branded toothpaste, and the other three are a series of photos that appear to show the gradual decrease of a pimple on a model’s forehead.

A similar claim was also shared on Facebook here, here, here, here and here in Thai and here, here and here in English. 

The claim is misleading; health experts warn that some ingredients in toothpaste can irritate the skin.

On January 16, 2020, the British Association of Dermatologists tweeted: “FALSE! Toothpaste does include anti-bacterial and anti-inflammatory ingredients, but it can be irritating to the skin and causes severe discolouration. You should instead use targeted acne treatments which are safe to apply to the skin.”

This October 14, 2019 report by the Cleveland Clinic, a US-based academic medical center, also says that toothpaste is “not intended to be put directly on your face”.

It reads, in part: “Many toothpastes contain ingredients like alcohol or baking soda that may help dry out a pimple. But, toothpaste also contains other ingredients that aren’t intended to be put directly on your face. She cautions that using toothpaste to treat a pimple could possibly irritate your skin.”

Several of Thai-language Facebook posts, such as this and this, mentions “Nop-Kao” toothpaste as an effective acne remedy.

Kru Tip, a representative for “Nop-Kao”, told AFP via phone on March 9, 2020, that while some people have used the toothpaste for curing acne, the main purpose of the toothpaste is to improve the oral health and reducing bad breath.

“The toothpaste is made from many herbs that can protect your teeth and gum,” she said.
