To begin, we’re going to start with a subtle skin retouching method that uses the Yellow channel to reduce skin flaws. Go to Image > Mode > CMYK. In the Channels panel, click on the Yellow channel. Copy this channel by pressing Ctrl/Cmd+A then Ctrl/Cmd+C.
Undo the steps by pressing Ctrl+Shift+Z or Cmd+Option+Z on Macs until you’re back in RGB mode. Press Ctrl/Cmd+V to paste and the Yellow channel will appear as a new layer. Name this layer “Flaws”.
Invert the layer by pressing Ctrl/Cmd+I then change the blending mode to Soft Light. Reduce the opacity until you get the results that you like. You can add a layer mask and erase the areas around the face if it is affecting the color/details of the surrounding areas. We don’t need to do this for our photo because the layer doesn’t affect the surrounding areas in any noticeable way.
Here’s the before and after of using the yellow channel to reduce skin flaws.
Before we do any sort of airbrushing on the skin, we’re going to use the Spot Healing Brush to reduce wrinkles and blemishes. Select the Background layer then duplicate it by pressing Ctrl/Cmd+J. Move this layer to the top then rename it to “Wrinkles & Blemishes”.
Use the Spot Healing Brush to erase the wrinkles and blemishes. Reduce the opacity of the layer to bring back some of the wrinkles and blemishes then position this layer below the Flaws layer.
We’re pretty much done and as you can see in this before and after preview, the skin looks a lot better than before.
If you’re happy with the results, you can stop here. But if you want to continue with some more dramatic skin retouching techniques, follow the rest of the tutorial to learn how to airbrush skin and reduce discoloration in the skin.
Before we proceed, convert all your layers into a single Smart Object. To do this, Hold Ctrl/Cmd and select all the layers. Right-click on the layers then choose “Convert to Smart Object”. This will save you time by letting you make changes to the faces at a later time without having to undo and redo everything. Rename this layer to Original.
Duplicate the layer then rename it to “Smoothness”. With the Smoothness layer selected, go to Filter > Blur > Surface Blur. Set the Threshold to 255 levels then adjust the radius so that you can barely make out the face.
Reduce the Threshold until you can just start to make out the details. The skin should still be very blurry. Click OK to apply the filter.
Duplicate the Original layer then move it to the top. Name this layer “Details”. This layer will be used to restore the details lost in the Smoothness layer.
Go to Filter > Other > High Pass. Adjust the radius setting until you can barely bring back the details.
Change the blending mode of this layer to Linear Light. The skin looks cleaner, but it looks overly airbrushed and has a fake plastic look to it. This may work well for younger subjects with fair skin, but for skin with more complexions, you’ll have to reduce this for it to look realistic. Here’s what the airbrushing looks like before and after.
Now we’re going to mask out the color. Select the Details and Smoothness layer then press Ctrl/Cmd+G to group them. Rename this group to Airbrushing.
Add an inverted layer mask to the group by holding Alt/Option and clicking on the Add Layer Mask button in the Layers panel or by going to Layer > Layer Mask > Hide All.
Make sure your foreground color is set to white then select the Brush tool. Using a soft round brush with an opacity of 50%, paint around the skin areas. Adjust the opacity of the group to fine tune the amount of airbrushing applied to your photo.
Select the Eye Dropper tool then sample a color from the skin that you want to colorize the skin towards. Make sure that your eyedropper tool is sampling all the layers. Collapse the Airbrushing group then add a new Solid Color adjustment layer from your Layers panel or by going to Layer > New Fill Layer > Solid Color. It should have your foreground color automatically selected. Click OK. Change the blending mode of this layer to Color.
