Injection lipolysis of lower cheeks for sagging? Age 35. (Photos)

Recently I have visited a plastic surgeon to discuss possible solutions about my sagging cheeks and procedures that would help me maintain more youthful look for longer. The doctor suggested doing the Injection lipolysis of my lower cheek area and advised me to do exercises (facial yoga) to tone my upper cheek muscles. At the moment I am 35 years old. Could you please share your view on my doctor's suggestions? Would you recommend Injection lipolysis to be used on face or not?
