Open the photo to be processed and select the Repair Brush tool in PS. Move the mouse to the part of the dark circles, hold down the Alt key and click on the normal skin area next to it for sampling.
Then, gently brush the dark circles with the repair brush tool. You don't need to brush it perfectly at one time, you can apply it several times to make the color gradually uniform.
Then, adjust the opacity of the layer to better blend the dark circles and the colors of the surrounding skin. You can see the natural effect by reducing the opacity, which can generally be adjusted to about 50%.
Next, deal with the bags under the eyes. Select the oval box selection tool in the selection tool, and draw an oval box selection in the small bag with the mouse. Please note that the selection box should include the entire pouch area.
Select the liquefaction option in the filter menu. In the pop-up dialog box, use the shrink tool in the toolbar to gently drag the pouch area inward. Be careful not to pull too much, lest the effect be unnatural.
After the liquefaction operation is completed, click OK to save the picture.
Through the above steps, you can use ps to effectively deal with dark circles and bags under your eyes. Remember to gradually repair the color of dark circles, and pay attention to adjust the opacity of the layer to get a natural effect. Be careful when handling the bags under your eyes to avoid the unnatural appearance caused by excessive pulling.
