Essential oils in perfumes
Synthetic chemicals are widely used in perfumes as they tend to be much cheaper than essential oils which offer a natural form of scent. It is often these synthetic chemicals which set off allergic reactions but essential oils can also cause reactions in some people.
Essential oils are used in many natural skin care products because of their remarkable effectiveness in both adding scent and having beneficial effects on skin. Unfortunately for those who have allergies to essential oils, this can restrict their use of even the most natural of products.
