Katie Piper hiking Yr Wyddfa with burns survivors

Piper, 40, was left with serious injuries and permanent scarring after an acid attack in 2008.

She had hundreds of surgeries to repair damage to her face and eyesight following the attack on the orders of her ex-boyfriend.

Ex-boyfriend Daniel Lynch and Stefan Sylvestre, the man who threw the acid, were jailed for life in 2009.

Piper lost sight in one eye but doctors at the Queen Victoria Hospital, in East Grinstead, restored it.

She set up her foundation in 2010, and the charity is celebrating having helped 99 burns survivors, and provided residential rehab to 20.

“I think a burn injury is incredibly difficult to cope with, and it’s not the case of having treatment, you’re cured and everything’s okay, it’s physically very debilitating,” Piper said.

“Once you meet us, there’s no limit – you never have to leave us, we’re here for you forever.”
