16IU Botox is way too little between eye brows

[i<3cats]

90$ 16IU by a cosmetician, my muscle is a bit weaker (reason was to get rid of the habit of squinting + small fold)

What is a better dose between brows (+balancing forehead muscles so they dont sink in the inner part)?

Before

After (2.5 weeks after, barely any difference)
