Chemical Peel or best solution for a refresh at 60

60 year old female with sun damage, dark spots, some acne scars, large pores, wrinkles are not bad except for smile lines that go down past mouth that bother me.  I have jowels due to being slightly overweigh, my neck looks pretty wrinkly with a scar from surgery.  My skin is quite elastic but is starting to thin and damages easily as I age.  Is a chemical peel a good solution for me if I have concern with an actual face lift.  Also do you recommend the new threading procedures to help neck and jowel area?  what is the best bang for my buck for an overall, refresh.  (not rich).  Tried the botox and fillers but they are too expensive considering they don't last long.
