Injectable anti-aging

Human skin is the largest sensory organ. Due to the presence of a branched network of nerve fibers ending in sensitive receptors in the surface layers of the skin, it provides the perception of various types of sensitivity. On average, one square centimeter of human skin has 100-200 pain receptors, 12-15 cold receptors, 1-2 heat receptors and about 25 tactile receptors.

This proves the importance of pain as a protective reaction to the aggressive influence of the environment on a person, so that the task of pain receptors is to warn the body of impending danger.

Pain sensations are perceived by free nerve endings of sensitive nerve fibers. There are no areas on the human skin where pain receptors are completely absent, but they are unevenly distributed in the tissues. They are most concentrated in the area of ​​the fingertips, on the face and on the mucous membranes.

Sensitivity to pain stimuli also depends on the emotional state of a person, his psyche, gender (men are more sensitive to pain), biorhythms (as critical days approach, pain sensitivity increases in most women and the effect of painkillers decreases significantly). A significant role in the perception of pain during injection rejuvenation procedures is played by the patient&#39;s motivation.
