Is it worth putting more filler in valley areas to even out?

I've had under eye fillers replenished about once a year for the past 4 years. This past time I am in a new state and went to highly rated certified plastic surgeon from a reputable location. This time i got bumps and valleys. i went back to surgen who dissolved area closest to my nose. 2 days later the area looks larger. Did Hyaluronidase not work? Is it worth putting more filler in valley areas to even out?
