WARNING: GRAPHIC IMAGES

A teenager has suffered second-degree burns after friends sprayed deodorant on her in a dangerous challenge sweeping school playgrounds.

Ellie Prescott from Bristol could be left needing a skin graft after a group former friends sprayed Lynx deodorant on her arm at close range, leaving it blistered and burnt.

Her mother has now issued a warning to other schools in a bid to clamp down on the "horrendous" trend which has injured several youngsters.

The deodorant challenge sees teens filming themselves holding the spray a few inches above them before pressing and holding the aerosol to the skin for as long as possible.

The aim is to outdo each other to see who can endure it for the longest, the MailOnline reported.

Jamie Prescott said her daughter, who has recently moved from the Chipping Sodbury School to Bristol Technology and Engineering Academy, still has to visit a nurse some two weeks after the incident.

Now Ellie, who is in Year 10, may need a skin graft.

Her mother told Somerset Live: "She went out and met with [friends] ... for a couple of hours.

Apparently, when they asked her to put out her arm she did it but she had no idea of the consequences and hadn't even heard of The Deodorant Challenge before that point.

"Since then other children have asked her what is wrong with her arm and when she has told them, they have then replied that they have also had it done to them and showed her their scars.

"It is still weeping excessively."

Ellie, said the game has been played in both her schools.

She said: "It seems fairly common, a lot of people have showed me their arms after doing it.

"My new school has sent out a warning to everyone about the dangers of it happening."

Her mother added: "I seldom rarely do this, but on this occasion, I would like this post spread wide and far.

"For any parents who have children, please, please sit them down and show them these pictures.

"The pictures below are that of my Year 10 daughter's arm THREE WEEKS ON which may still as yet require a skin graft.

"It's just horrendous and needs stopping."
