Hi, My Daughter Seems To Have Taken The Salt And

Hi,
My daughter seems to have taken the salt and ice challenge on her arm without our knowledge. she just told me now that she has got some marks. From the pic i see that she send me it looks like burns, am worried, am in office what can I ask her to apply as an immediate relief. is Flammazine ointment good for it, or is there anything else that you can suggest. I am so worried and hope she doesn't end up with scars. Can you advise please.

Thanks,
Trini Alexy John
