Natural Skin Retouching

I'm in need of a photo editor who specializes in retouching. The primary focus will be on skin smoothing, and the end product should look very natural without appearing overly smooth or artificial. There are many shadows on his arms and forehead from the leaves. Can this be fixed?

Ideal skills for this job would include:
- Proficiency in photo editing software
- Strong attention to detail
- Ability to create natural-looking edits
