TikTok has become a significant tool for people who want to learn about health, beauty, and make-up tips that they can’t find anywhere else on the internet.

Some of the strange yet useful fads that have emerged on the app include curling your hair with socks or prepping your skin for summer.

However, some of these trends have shocked medical professionals, who have urged TikTok users not to try them for the risk of permanent damage. The most recent one is the calamine lotion make-up fad, which has the potential to induce serious reactions and skin damage.

Some TikTokers, especially those with oily skin, have been using the medicine as a primer. They apply calamine on their faces before applying foundation to provide a base for their makeup as it is said to absorb excess grease.

In an interview with Daily Mail, dermatologist Dr Alia Ahmed at Frimley and Barts Health NHS Trusts said leaving calamine lotion on areas like the face for prolonged periods, either under or as makeup, can lead to excessive skin dryness, seen as scaly or flaky patches with redness.

She added calamine draws “moisture out of the skin” and “exfoliates.” Over-exfoliation, on the other hand, can lead to serious issues such as “rashes and irritation, and ultimately could cause damage to the skin barrier.”

TikTok has evolved into an essential source of information for people of all skin types looking to personalize their skincare routine. However, this one hack is not at all recommended by skincare experts.
