Here is the result of both cheek wrinkles being slightly lighter.




In the next two examples,  I am using the Clone Stamp to replace one area with another area I have selected. Notice the wrinkle above the nose. I select the Clone tool and then holding down the ALT key, I select right above the wrinkle. I then let go of the ALT key and drop the circle to the wrinkle. Holding down the mouse key, I drag the circle across the wrinkle and replace the wrinkle with clean skin. This takes practice but works well. You can see the before and after.
