There are a few things you can do to smooth wrinkles out of photos in Photoshop. The first is to use the “Smoothing Layer” tool. This tool allows you to smooth out the wrinkles in your photo by adjusting the size and shape of the layer. The second thing you can do is use the “Curve Mask” tool. This tool allows you to create a mask that will only be applied to certain areas of your photo. The third thing you can do is use the “Stroke Tool” to add a stroke around each wrinkle. Finally, you can use the “HDR” effect to make your wrinkles look more realistic.
