How to Reduce beard stubble in Photoshop

This video, produced by Photoshop Universe, teaches how to reduce beard stubble or 5 o'clock shadows from male pictures. We are shown how to use the dust and scratches filter, layer mask, as well as the advanced layer style command "blend if" on the underlying layer helps us to make this possible. The first step is to duplicate the layer and then select filter, noise, and dust and scratches. The second step is to apply some dust and scratches to the beard selection. Finally we blur the layer to make it appear as though the stubbles have been changed to a 5 o'clock shadow. Using these steps, Photoshop can clean up the stubbles on just about any beard in a male portrait.
