A mother has highlighted the dangers of a new craze called 'the deodorant challenge'.

Mum Jamie Prescott, posted a picture of her daughter's blistered arm on Facebook, urging parents to discuss the dangers of the game with their children.

The graphic image showed Year 10 pupil Ellie's painful burns - which her mother claims may require skin grafts.

Speaking to Somerset Live, more than two weeks after her daughter was injured, Jamie said: "She [daughter Ellie] still regularly has to see a practice nurse and go to the surgery once a week.

"The incident happened on Tuesday (April 18), but I did not notice anything until she came home from school on the Wednesday as it had blistered up a lot by that stage.

"As you can see from the yellow padding, it is still weeping excessively."

So, what is the deodorant challenge and why is it harmful?

What is the deodorant challenge?

The playground craze involves children holding a can of aerosol deodorant close to their skin and spraying it for a prolonged period of time, which causes it to cool.

It's not a completely new craze, and in the past has been referred to as 'frosting'.

Jamie said her daughter went to a local park with some friends, in Yates near Bristol, when the incident happened.

Speaking to Somerset Live, she said: She went out and met with them at Kingsgate Park 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."

Why is it harmful?

Ellie's arm blistered 24 after the incident

Depending on the duration of exposure, most injuries only burn the outermost layer of the skin. However, if it's done for too long, the skin will freeze and deeper layers of the skin's tissue will be affected.

The burn may itch and blister, causing it be very painful.

How is the burn caused?

The burn is caused by pressurised gas within the spray cooling down quickly. The decrease in temperature freezes the skin causing frostbite.

This type of frostbite is similar to a burn, if the burn is severe it can cause permanent scarring on the skin.

If the burn is fresh the skin should be washed straight away with warm water to remove any residual from the chemical.

A burn or blister may appear the following day.
