Without an in person consultation it would be difficult to determine the how. However, if you are dealing with an accredited, board certified surgeon, he/she will be able to devise the proper framework to meet your goals. You can begin with the injectable/filler route and determine if your skin rejuvenation has worked to your liking. And you can also research the fat transfer/grafting route - which may also lead you to your goal.
I wish you the best of luck, we have covered many of these topics.
