Does the sensation vary significantly depending on the area where Botox is injected?

As I looked into Botox, I realized there are so many different areas it can be used on, lol. Between the eyebrows, forehead, around the eyes, jaw, trapezius muscles, and even the calves... The range of applications is wider than I thought, which makes it even more confusing. So, I also became curious about how different the feeling is depending on the area.

For example, I heard that frown line Botox softens the facial expression, jawline Botox makes the face look smaller, and trapezius muscle Botox changes the shoulder line, so it seems like the effects are quite different for each. I am also curious if the actual noticeable difference is that significant.

I am also worried because I heard that discomfort and the adjustment period vary depending on the area. I heard that some areas are barely noticeable, while others take time to adjust. Since it is my first time, I am also struggling to decide which area to choose.

I'm looking for a natural-looking change, and I'd also like to know which area is the safest choice for a first Botox injection. I'm worried I might regret it if I start on an area that looks too obvious lol.

If anyone has tried Botox on various body parts, please share a comparison review!! I'm also curious to know which area you were most satisfied with.
