Is it good to get forehead Botox and glabella Botox together?

Hello. Recently, I have been concerned about my forehead wrinkles and frown lines, so I am considering getting Botox.

I noticed that many clinics recommend forehead and glabella Botox together, so I am wondering if it is definitely better to get them done at the same time. I would also like to know if the results are more natural and satisfying when both areas are treated together compared to just one.

I have also heard that getting hit only on the forehead or between the eyebrows can make facial expressions look awkward or make wrinkles on other parts of the face appear more prominent, so I am curious if that actually happens.

If you are getting Botox for the first time, you may wonder whether it is better to treat two areas together or to get just one area first, check the results, and then add another.

I am curious about the extent of the cost difference, whether there is a difference in the duration of results when administered together, and whether adjusting the dosage is important for natural-looking results.
