Doctor said I need cheek fillers rather than tear trough? Advice? (photos)

Thanks for the question.
Cheek fillers would only add volume to your cheeks but would not affect the line between your eyelid and cheek. 
I would suggest contacting an experienced plastic surgeon for a second opinion.
Good luck

If you are concerned with your lower eyelids, then I would inject your tear troughs. You have full cheeks already. Filling the lower lids can make you look younger and less tired. Botox is another add on that will help prevent crows feet and forehead wrinkles. Make sure you seek a consultation from a Board Certified Dermatologist for filler and botox.
