If you are familiar with the healing tool, there is another tool that is very versatile in retouching portraits.
I use this tool in conjunction with healing tool.
(Check out this blog post: Removing acne with Photoshop)
It is called the Patch tool.
Have you tried using the healing tool to get rid of eye bags? Good luck with that.
I use this especially when there’s a large, contiguous area that I need to retouch. For example, eye bags, scars, etc.
If you are already familiar with the healing tool, you can add the Patch tool to your workflow.
