Early 20s with gaunt face. Would fillers be the solution? (Photo)

I am missing a lot of fullness in the mid to bottom portion of my face. My cheeks are hollow and there is noticeable asymmetry unless I disguise it with makeup. A lot of people think that I have lost a large amount of weight at some point but that's not the case. I was hoping fillers could fix this. What type of filler would be best and where would you suggest they be injected to create fullness in my lower face? Thanks so much in advance for your answers
