So you pull up the picture, then go to Filter>Blur>Surface Blur. Adjust the Radius and Threshold to where you want it. The more you mess with it, the more you will get an idea of what looks the best. So here's the picture side by side after the surface blur.
I just love how it evens the skintones but doesn't look totally "Photoshopped"
The other problem with this photo is the shiny forehead. So I found a way to fix that, too! It's SO easy and doesn't use anything we haven't already used on this blog.
