Dr. Tim Pearce, a cosmetic clinician from the UK with over 10 years of experience. Recently, he mentioned on his Youtube channel that the last thing every injecting doctor wants to see is complications. He believes that the main reason for complications is related to the depth of injection. What exactly do injectors mean when they say “superficial,” “deep,” or “moderate.” The doctor gave detailed instructions in the video so that the recipients can perform the injection with more confidence and clarity.
When we treat the periorbital and lateral corrugator supercilii muscles, which is just above the midpupillary line, the muscle itself is very close to the skin or embedded in the skin. Therefore, any operation under this muscle is high risk and no reward. As it happens, there are also small pores, the passages through which blood vessels, nerves, and arteries pass from the orbit. These channels are very close to those deep injection points. Therefore, injections “deep” above the eye are high risk.
In addition, it is particularly dangerous to inject too deeply into the orbicularis oculi muscle, especially the lower and outer part of the eye. So if you’re trying to reduce wrinkles here and you go through the muscle, remember that the orbicularis oculi muscle is underneath a very thin layer of fat, very superficial — a layer of skin, a thin layer of fat, Then there are the muscles. You only need to insert the bevel of the needle by a millimeter or two. If you go deeper, you actually go through the fat, and the next muscle you encounter is the origin of the zygomaticus major, which could theoretically cause the corners of the mouth to droop, especially if you inject too low, which could cause an asymmetric smile, This is bad. One of the best examples of superficial injections is the superior portion of the orbicularis oculi muscle, just below the eyebrow. When you try to give a slight brow lift in this area, you are injecting into the dermis layer of the skin and the surface of the muscle. Underneath this layer of muscle is a thin layer of fat, and then the orbital septum and orbital area, which is where complications can occur. There are no benefits to deeper injections, only risks. So this is an important area that requires a very, very superficial injection. This concept applies to basically any part of the orbicularis oculi that you try to inject.
Injections “deeper” into other areas of the face are more effective and safer. For example, the masseter muscle is sometimes a more suitable site for deep injections. The same goes for the chin and medial corrugator muscles. This is because of the anatomy of the muscles. Take the medial corrugator muscle, for example. It attaches directly to the bone, which means if you inject deep, you hit it right in the middle of the muscle.
I hope a lot of people involved can get down to the millimeter level, and if you look at different parts of the face, the difference at the millimeter level is actually pretty big.In the video, the doctor did not give specific depth measurements, because it all has to do with the location of the injection. The injector needs to understand the various levels and anatomical structures, as well as the feeling of injecting at different levels.
