1, open the original material, here I set the resolution up to 250 pixels, and then make a simple grinding skin, here is the use of Portraiture plug filter, you can also manually rub skin.
2, a new layer, painting skin. My skin color here is: #d8ad9e, reduce the opacity is: 50%.
3. Create a new layer, turn off the skin layer that you just added, plus the dark part. Look at the original image and darken the black place. Draw the color of each dark part with a straw, draw slowly with the brush, draw well and apply evenly with the smudge tool.Classification:
