Some oils are best for wearing; and others are most popular when used in an oil burners to make your surroundings smell better. There is no real difference in the oils though. Designer oils (such as White Diamond, Chanel No 5, or Polo) have fragrances that people normally wear. Other fragrances (such as Strawberry, Chocolate, or Frankincense) are more popular for burning. But you could burn a wearing oil; and you could wear a burning oil if you wanted to. The oils are made the same basic way. It is a matter of personal preference if you wear an oil or if you burn it.
