The purchasing method is as follows:

1. The prices of essential oils extracted from different places of origin and extraction methods are very different. This is just like buying tea, which is divided into many grades. The same type of tea may have different prices, and some teas may even be sky-high prices. In many cases, it depends on personal taste and consumption values. You can buy it if you feel satisfied after tasting it.

2. When buying aromatic essential oils in a store, be sure to ask about the ingredients, usage, and contraindications. Regular essential oil products should be contained in small dark bottles with a drop-shaped mouth. Many so-called "essential oils" sold on the market have been added with mineral oil and essence, and can only be used to light aromatherapy stoves to smell fragrance. Only pure aromatic essential oils extracted from plants can be used for beauty care.

3. Go to several stores and make a comprehensive comparison. Do not buy some synthetic essential oils for cheap. Not only does it have no beauty and body health benefits, it may also be harmful to the body. Before purchasing, ask whether the essential oil is single or compound. It is recommended to use compound essential oil, and then read the instruction manual to understand its safety.

4. Be sure to buy from regular shopping malls or chain beauty salons. Pay attention to whether the essential oil label indicates the plant’s scientific name, origin, purity, registered trademark, and production date. It is best to purchase the essential oils you need under the guidance of professionals. Be sure to read the instructions for use carefully and do not mix or prepare essential oils without authorization.
