Mesotherapy is a modern form of therapy that consists of injecting medicines, vitamins and minerals as close as possible to the area that needs treatment. It is an astonishingly effective technique in aesthetic medicine as it treats layers of the skin, which are hardly penetrated by other non-invasive treatments .
To understand better how mesotherapy works, it would be essential to make a reference to its etymology; the word meso means `middle` in Greek and refers to the mesoderm which is the embryonal tissue that appears in the third week of embryonic development of the human body and which later forms the skin and the connective tissue. The word `therapy` derives from the Greek term for `healing`. For this reason, the healing effects of mesotherapy are not only seen in the area treated; they can also act as a regulatory therapy that affects the whole body. Furthermore, if we were to find a word to define mesotherapy, we would best describe it as a [technique" – a technique of application, for, when we speak of mesotherapy, we refer to the manner in which we inject the skin in order to achieve different effects.
These effects range from the management of pain to the treatment of scars and smoothing of wrinkles. Therefore, mesotherapy could be defined as an intradermal and loco-regional [therapeutic technique from general medicine" as it was defined by the French Academy of Medicine in 1987 . Mesotherapy uses all of the injectable drugs of our pharmacopeia, as long as they are compatible with the intradermal route and can be injected as close as possible to the area we want to treat.
In aesthetic medicine there are several indications for which we can successfully use mesotherapy. In this article we shall have a closer look at the most important ones, such as facial rejuvenation, Mesolift, Mesobotox, and mesotherapy to treat cellulite. We will also give a general insight into how mesotherapy is safely performed and what instruments and medicines are required for each indication. It is worth noting that mesotherapy is not only used to treat ageing skin, but also it prevents the skin from ageing.
