How to address premature sagging of face? I’m 28 but I get told I look 10 years older all the time.

You would be a great candidate for tear trough and mid face dermal fillers. In addition, I recommend Morpheus 8. Morpheus8 is a non-surgical treatment for full body skin resurfacing, skin tightening, and fat reduction of stubborn areas. It uses minimally invasive fractional radiofrequency energy (RF) to penetrate the skin deeper than other microneedling devices, triggering the skin’s natural healing response to promote skin tightening and lifting. Best of luck, Dr. Nima!

The best recommendation would be on consultation to actually see the face but over all considering yuo age you want to try something thats more natural so ultherpay would be great to stimulate the collagen and give the lift and then good skin care and then lastly fillers if need. 

Hello and thanks for your question! Early facial aging can happen for a number of reasons including genetic (thanks Mom and Dad!), sun exposure, and significant changes in weight. At your age, you can augment some facial aging with many non-invasive measures, but the key is really to be very careful with HOW MUCH you do. The risk is that your efforts to camouflage (or reverse) the aging process end up changing your facial shape in a way that is "different" but not necessarily a more "youthful" version of you. While people certainly also get surgical procedures at your age, I would recommend you speak with a certified facial plastic surgeon to figure out the best step for YOU. Good luck!

A combination approach will give the most improvement. Fillers, lasers, and microneedling/PRP can improve under the eyes and improve facial volume. My patients try to get non surgical treatments to avoid surgery. We use PRP and stem cells there often. I suggest consulting with an expert to develop a treatment plan best suited for your short and long term goals. Best, Dr. Emer

I do think you would benefit from volume restoration in the midface using filler. I usually recommend Sculptra Aesthethic or Restylane Lyft when correcting midface/cheek volume loss. I think, in your case, Sculptra may give you a more complete result. I would also consider one of the newer flexible gel hyaluronic acid fillers, Restylane Refyne or Restylane Defyne, to soften your laugh lines. 

I don't see your full face so it's a little limited, but the main issue I see is loss of volume in your face, especially under the eyes and cheeks. The lower portion of the temples also seem concave, so I think there is some volume loss there too. 
Volume loss at any age accentuates the aging process, so I suggest starting from restoring volume. Find an experience injector and plan out a strategy to systematically restore facial fullness and that should go a long way toward looking more your age.
