Basically, an essential oil contains aroma compounds found in plants. They are extracted from plants and are often fragrant or have distinctive scents that set them apart from artificial oils and products. Distillation is often the process done in order to extract oils from plants. Steam is essential in being able to get the oils out of the plants and in being able to preserve them well. Throughout history, essential oils have been used for a variety of reasons, such as for medicinal and aesthetic purposes. Using essential oils in beauty products is ideal because they come from plants, which means that they are natural and there are no side effects to using them. Using essential oils is also a form of aromatherapy. Plus, being able to create your own beauty products with the help of different essential oils would be so much fun. Aside from being able to use the products on your own, you may also sell them to your friends and colleagues.
