1 First of all, we should scientifically understand the working principle of the foot patch, mainly by stimulating the acupoints and reflex zones on the soles of the feet. This is similar to foot massage, which can often stimulate the soles of feet, regulate endocrine and enhance body excretion and metabolism. There is no doubt about it.

2. Secondly, it depends on the physical phenomenon of black hair oil after scientific use of foot patch. Because the color of the raw material itself is black, the black hair oil on the foot paste naturally appears black after reacting with the sweat on the sole of the foot. Hair oil is just like cosmetics. Oil is easily absorbed. If there are ingredients such as orange essential oil in the raw materials, it will naturally send oil.

As can be seen from the above, the foot patch is a physical therapy product at most, which has certain effect, but it is not so magical and can be used, but don't be superstitious.
