Frequency separation is a powerful photo editing technique, especially for skin retouching, that splits an image into two layers: a low-frequency layer for color and tone and a high-frequency layer for fine details. This separation allows editors to smooth skin blotchiness and blend colors on the low-frequency layer while fixing blemishes and preserving natural texture on the high-frequency layer, preventing the unnatural "plastic look" of heavy edits. If you’ve got pimples, a blemish, or a tattoo that’s distracting from what you’re trying to convey with your subject, you can try the frequency separation.
Therefore, many photographers will try Photoshop to use frequency separation to retouch skin in the photo, and we will also introduce a photo editing tool for you that is comparable to Photoshop but easier to use - FlexClip. Please read on!

1# How to Use Frequency Separation in Photoshop
With Photoshop’s frequency separation, you can retouch either the high or the low frequency without affecting other areas — but it doesn't apply any actual edits to your work. Instead, it allows you to break an image apart so you can work on different sections, like modifying skin texture independent of color or shadow. Photoshop’s frequency separation can create a canvas for you to work within precisely, so you’re able to make fine adjustments with other tools.
Once you’ve used frequency separation to parcel out areas of your image, you can then use layers, blur effects, shadow and color features, and blending to help you change the shape and tone of any image.
Frequency separation can take a lot of steps, but it’s an opportunity to learn Photoshop actions — a feature that allows you to record a particular set of operations so you can do complex edits and techniques in a single click. They’re handy when you need to make a series of edits that are the same every time.
Step 1
Select Window › Actions, and click Create New Action in the sidebar that appears. Name your action and select Record, and this will begin the recording for the frequency separation.
Step 2
With your image open, right-click the layer and select Duplicate Layer. Then click the lock icon in your background layer to allow it to be modified. From there, name the top layer “Skin+Texture” and the bottom layer “Shadows+Color.”
Step 3
Combine the layers into a group by selecting both and navigating to Layer › Group Layers.
Step 4
Select the Shadows + Color layer, use Filter › Blur › Gaussian Blur, set the radius to 5px, and click OK.
Step 5
Select the "Skin + Texture" layer. Select Image › Apply Image. Choose Shadows + Color in the Layer selection menu, Subtract in the Blending menu, and set Scale to 2 and Offset to 128. Click OK.
Step 6
In the Layers panel with Skin + Texture selected, select Linear Light in the Blending modes menu.
Step 7
Congratulations, you’ve set up your two layers for retouching. Click the stop icon in the Actions sidebar, and the action will be saved so in the future all you need to do is open an image, click the action, and you’ll be ready to work.
