I want to get filler injections, but I'm really conflicted.

Lately, I keep hearing that I look haggard because I've lost so much weight in my face. I'm stressed about it, so I'm thinking of getting a little filler in the sunken areas to refine my facial lines.

From what I've heard, the doctor's technique and molding skills account for over 90% of the success with fillers, so they say that if you get too much injected, it can clump or slide down. I really don't want it to look artificially puffy; I just want to fill in the sunken areas naturally, but choosing a clinic is such a hassle.

It's such a popular procedure; are there any of you who had a successful filler injection and are satisfied? Did it settle perfectly and look natural without looking awkward? I'm really tempted to get it lately haha. Please let me know.
