A seven-year-old girl is suffering from a rare skin condition that makes her skin blister at the slightest touch.

Isla Grist suffers from epidermolysis bullosa, a disease which featured in the award-winning documentary The Boy Whose Skin Fell Off.

Sufferers of EB are often referred to as "butterfly children" as their skin is said to be as fragile as a butterfly’s wing.

Isla, from Inverness, is so vulnerable she can suffer severe wounds from something as simple as falling over while dancing.

Her mother, Rachael, said: "If she’s knocked or falls over she damages her skin - either her skin comes away or she gets a blister. We have to treat her blisters by lancing them or they just grow and grow.

Even the inside of Isla’s mouth and throat can blister so she is fed overnight through a tube fed directly into her stomach.

Ms Grist said: "We have to be very careful. It affects her internally as well, eating is painful and going to the toilet, too."

"When she was born she was missing skin on her feet and hands. We didn't know what it was but we were very lucky one of the doctors did."

Despite her condition, Isla’s family are trying to ensure she lives a normal life.

Ms Grist said: "We just try to normalise life as much as possible. It is difficult and there are lots of things she would like to do. She would like to climb and swim like her sister."
