I don't buy into the expensive salon products at all! You can get better results from the simple routine of Retin-A (or a retinol product if you can't tolerate Retin-A yet), Vit c serum (you can make your own), sunscreen, and facial exercise and massage.
You can buy Retin-A online much cheaper than in the pharmacy in the US.
You don't need the fancyshmacy Vitamin C serums with the fillers and fancy bottles. You can make your own and customize it in any way. There are lots of threads here about making your own.
Ditto, sunscreen. Lots of info here at SCT. Needs to be stable and high SPF/PPD.
Facial exercise/massage will tone the muscles and skin to the point that you will get results similar to (or better than - no scars!) plastic surgery.
Sure cleanliness is important. But you don't need any high-priced cleansers with glycolic acid. A simple one will do the trick.
