The reason for the delay in the effects of Botox injections is due to the time it takes for the body to react to the injection. After being injected, some results may be noticeable after 3 or 4 days, but it may take a few weeks before the best results are achieved. It is important to note that Botox is effective for dynamic lines and wrinkles, which are associated with repetitive muscle movements and facial expressions. The most common reason patients think that Botox didn't work is because they see residual lines in the treated area.
Static wrinkles associated with aging, sagging skin, loss of facial volume or sun damage, for example, are not suitable for Botox treatment. After the first treatment, you may feel a slight feeling of “tightness” or a feeling of “heaviness”, which will decrease in 1 or 2 weeks. Botox usually takes 7 to 10 days if injected correctly for best results. While it ultimately depends on the patient, there are actually several advantages to continuing regular and consistent Botox injections. Similarly, constant injections of Botox can slow the progression of dynamic lines and wrinkles, since the muscles remain in a relaxed position for a long period of time. As Botox disappears, a greater range of motion and lines will become apparent, and facial movement will eventually return to pre-Botox levels.
Some patients may experience side effects after Botox injection, but these are usually relatively mild and go away quickly. A study using MRI technology has mapped the flow of Botox from injection to the cellular level of the muscle. This provides us with a deeper understanding of the timing of the effectiveness of Botox injections.
