Perfume is a mixture of frangnant oils... which gives a pleasant smell.evryone uses furfumes in this modern life but Perfume ingredients, regardless of natural or synthetic origins, may all cause health or environmental problems when used or abused in substantial quantities. some Perfumes may cause cancer also. even we they are also responsible for skin deseases... its not that we should avoid usage of perfumes but try to use it less....
  Hope it helps...!!!!
