They are the source of the scents of nature and may be used to add scent to natural products. Because of their concentrated nature and high cost to produce, only small amounts of essential oils are used in natural skin care. Besides, as essential oils may be irritating to the skin, they should never be used undiluted. In contrast to oils, floral/herbal waters are the aqueous extracts from flowers/plants. Naturally produced oils and aqueous extracts are made through distillation, steaming, or infusion techniques. These are slow and often inefficient processes that add to cost. But, the products generated using nonsynthetic approaches are much safer and healthier than those extracted with the use of artificial methods.
