My Forehead Felt Too Tight and my Eyebrows Became Pointy After Botox, Why?

I think the key to a good result with Botox is for the injector to understand the anatomy, how the different muscles interact, and how much to use in a specific area or group of muscles.  This is why it's really important to go to someone who performs the procedure regularly and understands these details.  In your case, things can be improved now if you like with a touch up procedure to control the elevation of the corner of your eyebrows, or you can wait for the effects to wear off in a few months.  The good news is that living in a large city like you do there are lots of experienced injectors who can get you the results you want.

You might have had too many insertion sites in the middle forehead so that the inner eyebrows are dropping as the forehead lifting muscle (the frontalis) becomes incapable of lifting the forehead. If you didn't have the glabella treated (but it looks like you did), then this area between the eyebrows should be done to help lift the inner eyebrows.

The inverted V is probably caused by too much injected in the central forehead and/or not enough in the outer forehead. You can achieve a more subtle look with less injection of total units

A unit of Botox is a unit of efficacy not a unit of measurement.  Every patient will need a different number of units to effectively weaken the corragator muscle to decease the vertical creases between the brows.  I   Botox is not an exact science.  Caution has to be used no the forehead where an over dosing of Botox will lead to dropping of the brows.  

To achieve a rested, attractive appearance with Botox your injector needs to have a good knowledge of anatomy and understand the interaction of the facial muscles. In your case, not only was the central forehead completely 'taken out" giving you that lovely frozen look but the use of Botox just over the inner brows dropped them giving you a Dog's Leg brows with a somewhat obvious raised outer arch.

You can do much better.
