Are these new and unproven trendy techniques?

Hardly. In the past 2,000 years, more people have been successfully treated with acupuncture than with all other health modalities combined. For thousands of years, the Chinese have known that beauty comes from the inside. At least as early as the Sung Dynasty (960 AD-1270 AD) Acupuncture rejuvenation practices were employed for the Empress and the Emperor's concubines to enhance beauty. The Chinese discovered and utilized ways to change the energy flow within the body to initiate the healing process for rejuvenation. According to a famous Chinese axiom, "Where qi goes, blood flows." Even for those unfamiliar with the principles of Chinese Medicine, it is known that increased circulation helps the body to look and feel better. Common sense would tell us that treating the underlying cause of why someone is aging is preferable to masking the outward symptoms and allowing further decline and dysfunction to continue within the body.
