Hi, after applying palmers coco butter lotion my grand daughter had what appeared as hives , swelling to the area applied, hands only. She reported a headache as burning she s 6 and hasn t experienced a headache before. I looked at her hands and noted the above; which all occurred less then 5 minutes after application.
