I often hear that I look tired, so I'm planning to get fillers.

I have had some facial asymmetry and sunken areas for a long time, so I have often been told that I always look tired. I have been hesitating because I was scared, but I have finally decided to take the plunge and get filler treatment to resolve my complex, so I am writing this inquiry.

After looking up reviews online, my biggest concern is that if the procedure is done incorrectly, it might look very artificial and puffy, making it appear unnatural. There are so many reviews, though... Rather than just filling it up completely, I want it to blend naturally with my original features and have smooth symmetry. I am wondering if the doctor carefully designs a customized plan based on my overall facial balance before the procedure. Also, do I need to take medication after the filler treatment? Is it okay to drink alcohol?
