Sounds like you need a med spa. A run of the mill aesthetician won't do much for advanced skin damage.  

IPL, TCA peel or any medical grade skin peel is a great way to combat the effects of living a good life- sun spots and other discolorations, fine lines, enlarged pores, dullness and blotchiness respond very well to these treatments.  

For deep set wrinkles and sagginess, a facelift is the nuclear solution. A consultation with a board certified plastic surgeon is the way to go.  You can try fillers like Juvederm at the med spa but don't go too overboard or else you'll end up with a huge cherubic visage that just screams, "I got work done, e.g. Mickey Rourke or Barry Manilow." These days, plastic surgeons operate med spas so you can shoot two birds with one stone.  

My aunt is in the business- in Korea. I'd meet with a few different establishments before you settle. It really depends on what you're looking for in terms of accomplishment and expectations. Good luck and I hope you find your solution. If you want to PM your specific target goal, I can come up with a suggestion/game plan for you. Don't forget to factor in downtime for recovery and always use sunscreen.
