Excuse me, what is the difference between silicone oil-coated acupuncture needles and ordinary acupuncture needles?

Acupuncture needle coated with silicone oil is a patented product applied by Yunlong Company 0 1. Generally speaking, acupuncture needles coated with silicone oil bring less pain when doing acupuncture. The specific reasons are as follows: the surface of the needle body is coated with silicone oil layer. Because the friction between silicone oil and the body is small, the needle is smooth, it is convenient to advance and retreat in the body, and the pain is small. Silicone oil is colorless, odorless and nontoxic, so it has no adverse effects on the human body.
