Skin blood flow significantly decreased with increase in age. Skin blood flow is 40% less at age 65 than at age 25. This is because skin blood flow decreases with decreased pumping blood from heart; skin blood flow significantly decreased with increase in total cholesterol and systolic blood pressure; less blood is redirected to the skin from other part of the body; blood vessel movement is impaired with aging and blood vessels are not relaxed to increase the blood flow.
Acupuncture increases blood perfusion and reduces skin aging
Acupuncture is used to treat many conditions in China. Its mechanism is based on meridian theory which is not accepted by Western medicine theory. Recent years researchers are trying to find how acupuncture works from a scientific aspect. Many research data suggested that acupuncture improves blood perfusion. For example, there was a study of acupuncture on 140 healthy volunteers. In this study, acupuncture was applied in LI4’ skin blood flow was measured using a Moor full-field laser perfusion imager before and after acupuncture stimulation. Recently study has shown that stimulating LI4 also increased facial blood flow and hand blood flow. After acupuncture of the right LI4 acupuncture the change ratio of mean blood flux in the left LI4 was increased significantly compared with the control group 60 minutes after acupuncture stimulation. Another study has shown that acupuncture at LI4 and LI11 increased blood circulation along the meridian. Study at ST36 point also has suggested increased skin blood perfusion around the acupuncture point in healthy subjects. In 22 healthy volunteers acupuncture at PC6 point increased microcirculation blood perfusion units along the meridian. Increased blood circulation was also seen at the back acupuncture point study. This also demonstrated in some conditions For example, in a study patients with dysmenorrhea were treated with acupuncture. After 10 sessions of acupuncture treatment, microcirculation was increased and the symptom scores, pain index, and visual analog scale decreased significantly in treatment group.
