I keep seeing these websites with images that have been brushed to the point where al the models look like realistic Simpsons.
Airbrush out the skin blemishes and then add a bit of texture.
I advise you create a new layer when applying and set layer opacity to around 28%.
Use either #eeeeee or #9e9e9e for coloring depending on the skin shade after brushing, those colors work well for me anyway.
