My fragrance oil bottle is caved in some on the sides. What is wrong?
There is nothing wrong with the fragrance when the sides of the bottle are caved in a little. This is called paneling, and it is a reaction that the plastic has with the fragrance oil that causes air to escape. We have our bottles specially treated to help prevent this, but unfortunately, it can still happen. The fragrances with a citrus smell are most likely to have this problem.
