This is a permanent filler. You must be fully informed and prepared to deal with the consequences when receiving permanent substances to your face.
I wanted only the temple region filled with a permanent product because, doing the math, is be spending way more on injections every 2-3 months over the course of time.
I had a photo with me of how I wanted my temples filled and my Dr. talked me into filling my brow-ridge area, based on the photo I brang along.
A year later, seems the weight of the filler in the brow area has brought down my eyelids a bit. There are spots that weren't addresses in the temple region (what I originally asked for) and what was filled now has lumpiness that can be felt, but not seen.
May need to go back to have the areas refilled.
