Now, select the layer you just created and invert the colors with the Control + I key combination.
Change the image mode with the drop-down that you will see on the layer. Select Vivid Light. The picture will turn gray and you will probably barely make out the silhouette of the face.Intense light mode
To visualize the relief of the face, apply the Gaussian Blur filter. You can access it from Filter and then Blur.Apply a blur
Increase the radius of the effect until you can make out the silhouette of the face.
Immediately apply the High Pass filter. Thanks to this effect, you will be able to merge the gray embossed layer with the layer below. Then, you will see the image a bit blurred. This effect is the one that blurs facial imperfections. For a natural look, you should play with the filter ratio to dilute the imperfections. Avoid overdoing it. When you think you have the right level, click OK.Apply a high pass filter
Once all this is done, it is time to retouch certain parts of the face. It is necessary to create a mask so that the changes only affect the areas we are interested in. To create a mask, click on the mask creation button.Create a layer mask
