There are many ways to lighten a face in Photoshop, but one of the most effective is to use the dodge tool. To do this, simply select the dodge tool from the toolbar on the left hand side of the screen.
Warning: This action may result in an artificial or “Photoshopped” look.
Then, click and drag over the areas of the face that you want to lighten. The further you drag, the more light will be added. You can also use the burn tool to darken areas of the face, if desired.
One thing to keep in mind when lightening faces in Photoshop is that you don’t want to go too overboard. A little bit of lightening can go a long way, but if you make the face too bright it will start to look unnatural. So be sure to experiment with the tool until you find just the right amount of lightness for your image.
