If you want to do this yourself there are a few ways, depending on your skill level. Probably the best way is a technigue called Frequency Separation, which allows you to change the skin color without changing the texture, but it's a somewhat advanced technique and not everyone will be ready to try it. For a simpler approach, I used the Clone Stamp and a layer mask.
On a new layer, use the Clone Stamp to replace the dark areas of the nose and eyes with nearby samples of lighter skin. For this first step, it doesn't need to be perfect. Here is what I got, but it's obvious that I did too much in many spots:

Next, apply a layer mask to this new layer and fill the mask entirely with black. This gets you back to the original image. Now use a soft brush and set the Flow to something very small... I used 5%. Using this brush, start painting with white in the layer mask to very slowly bring back the lighter skin from the Clone Stamp. Take your time and go very slowly. The idea is to very gradually lighten the skin and have very smooth transitions so that there is no obvious border with mismatched skin. Make sure to retain the shadows that define the actual shape of the nose because you want the person to still look the same. I only spent 5 minutes on this, but here's what I got.

As a final step, I added a bit of Noise to the lightened area to increase the texture.
