A SWEDISH teenager has grown her face back after an allergic reaction to a single paracetamol pill caused the skin to turn black and peel off.

Eva Uhlin, 19, has recovered her looks after suffering an allergic reaction to the common painkiller, bought over the counter.

The deadly condition, known as toxic epidermal necrolysis, attacked her body, causing her skin to blister, burn and scab.

During her illness, skin on her chest, arms, back and stomach fell off. At one point the damage to Ms Uhlin's face was so bad that her lips fused together.

''It felt like something was crawling around under my skin, I was in total shock - it was like something out of a horror film,'' she said. ''I couldn't believe what was happening. I had taken paracetamol many times before.''
