This is fairly easy, there's a lot of skin around. So the healing brush really is best solution. I revert to one of the other tools.
The Clone stamp tool The clone stam simple duplicate a source area that you can define like a healing brush. You use ALT+click. As this make an exact copy of the source area.
You have to be careful in selecting the source area. Because it is easily to make it change the structure skin. The best thing is you should use it with the opacity of brush is lower than 50% The Blur tool This tool is make the skin is cleaner and softer. You should use it to tone down very small park of the skin. This is can be done after you use the healing brush or clone stamp tool
