I've had a close look at her IG post. Quite a lot of filter and and the usual 'airbrush' of her neck, so that's probably why the burns look a bit odd.
Her right cheek looks swollen, puffy and pink. There's a line going from her ear to her jowl, underneath that there is a patch of white skin as if a thin layer has gone. They look like nasty burns, she was indeed very lucky. For all her faults, I wouldn't wish that kind of injury on anyone. Yes it was a ridiculous and an odd thing to do. It could possibly have happened the night before after a few drinks and she wasn't thinking straight. I haven't listened to her story, I preferred to read

I'm surprised she hasn't seen a GP. I don't know much about that kind of thing, but I would have thought it should be dressed, especially as she seems to suffer quite badly with psoriasis, her skin must be very sensitive already. As for her youngest daughter's comment? Maybe she was trying to comfort her Mum as they must have all been very distressed, and not what her parents needed on holiday.
It's the people who were around her I feel sorry for, that must have been very stressful for Mr and Mrs Sawalha, a very unpleasant and unfortunate accident. Especially as, again for all her faults, she was trying to do a good thing by taking her parents away for a break.
As for posting it on SM, I don't think I will ever understand why every second of their lives has to be broadcast. It's an addiction, surely?
