Once you have all the highlights painted, the skin tone should look smoother.
Step 8: Fix the color blotches
If you look closely at the image, you may notice color blotches that make the skin look artificial. To fix this, we'll use the Blur tool to blur out the edges. First, select Layer 1 which is the top layer with the skin color. Then, select the Blur tool from the toolbar. The Blur tool may be hidden with the Smudge or Sharpen tool. If you can't find the Blur tool, find the Smudge or Sharpen tool, click and hold on it and a menu should appear with the Blur tool you can select. Once you have the Blur tool selected, blur the edges of the blotches to make it blend into the skin.
Step 9: Reduce the effect
The skin tone is very smooth, but it makes the skin look too flat. To fix this, you can reduce the opacity of the Background copy layer.
