I'm not from Guangzhou
But I used essential oil in the beauty salon.
Essential oil is used to make partial weight loss, which can be directly applied to the parts you want to lose weight.
But when I was working in a beauty salon, the beauty salon staff used plastic brushes.
Rub the part you want to lose weight, make the part you want to lose weight hot, and let the fat burn quickly.
Then wrap it in plastic wrap to keep warm.
I don't use much, only a few drops on my thin arm.
With essential oils and elements, it is said that it is slimming and firming skin.
That's all I know.
