Viral videos of people having full-face “hot wax” treatments on TikTok have led to warnings from skin experts.
They show softened resin covering subjects’ face, mouth and neck – and partially penetrating their ears and nose – before being removed.
A barber posting some of the most watched examples says it is beneficial.
But the British Association of Dermatologists (BAD) said: “Attempting to wax inside your nose or ears is not recommended.”
A UK-based skin specialist has also raised safety concerns about the risk of obstructed breathing.
And one expert has suggested TikTok should add a warning.
But it has indicated the videos are excluded from its community guidelines on dangerous behaviour because they show skilled professionals.
