I had a lip piercing several years ago that entered my skin under my lip and came out through the top of my actual lip. I decided I didn't like it and removed it. When my lips are stretched, you can see that there is visible scarring through the middle of my lip. I have always wanted lip fillers (nothing too big, just average natural looking lips). Would the fillers fill my lips evenly, or would it be uneven and unattractive due to my scar tissue?
