i had restylane and Teosyal fillers in cheeks and tear troughs approx 10 months ago. The result was always a bit uneven, more correction on one side than the other and this stull the case so my right eye looks good still but left eye has more of a 'bag'. I am thinking about having a little filler added on the left side to make me a bit more symmeticral but am worries that I'll end up more uneven again. Does this problem happen often and is it easy to correct?
