Was SkinVive effective on plumping lips? Was it safe?

Hi, I was recommended by a licensed professional at a med spa to use half a syringe of Skin Vive for lip filler, as she didn't want to change my lip shape too much or overfill my lips. However, I later learned that it's not FDA approved for lips. Was this a safe idea? Or effective ? I see a subtle change but nothing major -- which is what she told me would look most natural and suit my face. I hope this was not a waste of money or ineffective. I like how it looks but not sure now....
