1. Look at the bottle: the essential oil contained in real rose pure dew will volatilize, so it is usually packed in dark bottles.
2. Shake it to see the bubbles: Shake it hard. If bubbles exist for a long time, it is false because the solution contains artificial chemical additives such as chemical emulsifier and surfactant. Although the real rose dew bubbles when it is shaken, the foam is large and disappears after standing for a while.
3. Open the bottle cap and smell it with your nose: it smells like wine, which is fake.
4. Add a little essential oil: about 1CC). Shake up and down hard. If the essential oil does not float up after 5 minutes, it should be judged that there is emulsified oil in it.
5. Look at the absorption effect: Generally speaking, the absorption speed of pure dew is relatively slow, because there is no substance such as alcohol added to help absorption, and many people think that "good absorption" is wrong.
The above is the method to judge the authenticity of pure rose dew, for reference only. It is recommended to choose a reputable merchant to buy.
