Generally, the factors that determine facial contour can be thought of as the bones of the face, which form the overall foundation, the muscles covering the bones, and the soft tissues such as the subcutaneous fat layer and skin.
If you understand this basic knowledge, you can clearly see the difference between square jaw surgery and Botox injections.
First, square jaw surgery is a procedure that permanently changes the shape of the facial bones, whereas Botox injections are a method that reduces the volume of the muscles covering the facial bones for a certain period of time.
Of course, depending on the indication, if the bones are not large and the muscles are highly developed, simple Botox injections can lead to satisfying results in a short period of time. However, after about six months, the muscles return to their original state, so it is important to keep in mind that repeat treatment is needed.
Unlike common belief, from a medical standpoint, repeated Botox injections can cause the body to produce antibodies, and there are reports that if injections are given too often, the body may become immune and the effect may decrease.
However, Botox injections are considered very safe, so you can expect sufficiently satisfying results with a simple procedure.
On the other hand, square jaw surgery changes the shape of the bones, so the area it affects is different from that of Botox injections, and the indications are also different. The results after surgery can also be considered permanent.
However, in the case of square jaw surgery, the results appear gradually over several months to a year as time passes, and they settle in more and more, whereas in the case of Botox injections, results begin to appear after 2 to 3 weeks, and the effect disappears after about 6 months.
In some cases, combining square jaw surgery and Botox injections can be expected to produce better results.
