"Bold glamour". It is the name of the latest viral Tiktok filter that, among other things, provides users with smoother skin, fixed eyebrows, highlighted jawbones, and a model-like "glow".

The technical design of the filter is also sharper than much of what we have seen before, where, for example, a hand over your own face does not interfere with the filter's effect.

'Incredibly realistic'

But Lisa Thorell, professor at the Division of Neuroscience at Karolinska Institutet, is critical.

"This filter seems to be so incredibly realistic. In the past, it has been seen that it is a filter and understood it. At the same time, we know from research that it doesn't really matter if people see that it is a filter or not, because you are negatively affected anyway, she tells SVT Nyheter.

She believes that the use of social media creeps down the ages - and that it is a problem.

"You shouldn't actually use social media until the age of 13, but we already know that a lot of people do. A report from the Swedish Media Council states that "13 is the new 16" because it is now already at the age of 13 that social media is used the most. Usage creeps down the ages more and more every year. It then has more negative consequences and the children get a big fixation on appearance.

"Finding new errors"

Thorell says there are always new trends for young people on the internet. The group most often negatively affected is younger girls.

" Young girls zoom in on certain specific body parts when they have taken a picture of themselves, to check that everything looks perfect before posting a picture. In similar ways, they zoom in on images of others they see on social media. It becomes an incredible fixation on the look that is not at all healthy, she says and continues:

"Many people report that they have found new faults in their bodies when they have used social media.

In the clip above you can see when SVT allows several people to react to the filter and what they see.
