Loss of lip shape and heavy philtrum after lip filler - how can I remedy this? (photos)

I am a 51 year old female and this is my only second time for lip filler. I had it done by my dermatologist 3 months ago. She used half a syringe of rha2. She injected only from the outside corners of my mouth. My philtrum is very heavy, and also around the outside of my lips is heavy. I feel I have loss of my true lip shape which I loved. One year ago, I had lip fillers with a plastic surgeon who used restalyne lift and less than half a syringe and the results were beautiful. Is there anything that I can do to remedy this? My dermatologist says to masssge the lips so the filler will fall into place. The first pic is three mos. out from rha2, and the second pic is three days after filler with a plastic surgeon. Thanks for your answers !
