I have been recieving no problems with boroleum because it seems like it is a natural product. I was experiencing rashes on my face and I am a type of person that has very sensitive skin. I tried every medications but it just kept making my face in worst so I became self-cautious about my face. Until, my mother told me to use petroleum and from then my skin is lookin extremely wonderful, no rashes, scars, redness, burns from my previous prescriptions.
