Do you have any tips on choosing a good place for forehead fillers?

I'm worried because my forehead is too flat ahead of a photoshoot.

Honestly, finding a place that does forehead fillers well is like trying to catch a star in the sky, haha.

I don't want anything too excessive; I just want it filled in perfectly naturally.

I've reached my limit with all the research I do online, so I'm asking directly, haha.

I'm curious to know what your criteria are for a good forehead filler place.

I want to go to a place that doesn't over-treat and where the director carefully oversees the design.

I desperately need information about clinics where you were genuinely satisfied, not just advertisements.
