While there is no substitute for an in-person evaluation in which the facial regions can be palpated and manipulated, from the photo provided there does seem to be flattening of the central portion of the right side the face as compared to the left and there is a downturning to the border of the left side of the upper lip when compared to the other side. Both problems should be readily amenable to fillers. A volumizing filler, such as Voluma XC, which I would choose in my NY office would help to reflate the right cheek region and balance it better with the left. (In my Israel satellite facility, where a far greater number of regulatory agency approved volumizers are available, I would opt for Stylage XXL for this purpose). For the vermilion border of the left side of the upper lip, I would choose Juvederm Ultra XC (NY) and Princess Volume (Israel). Make sure that you consult with a board certified aesthetic physician with experience and expertise in the use of injectable volumizers and fillers. Ask to see his/her before and after photos before agreeing to proceed. Best of luck.
