What is the best way to fix the old looking skin under my eyes? Fraxel laser? Filler in the tear trough, Surgery, cheek filler?

Im 39 Yrs old & Ive lost 10kg within the last 3 months now i look like I've aged 10 yrs. The area around my eyes looks sunken and fine lines have evolved into sad looking wrinkles. I've been advised this is due to the weight loss and that fillers are unsuitable & will cause sagging due to the thin nature of the skin . A lower bleph was recommended. Cheek filler another suggestion. I sleep 6 or 7 most nights. I have always used quality skin products and sunscreen since I was a teenager. Thank you
