We are going to start by removing skin problems. Select Healing Brush Tool. This tool lets you correct imperfections, causing them to disappear into the surrounding image. Like the cloning tools, you use the Healing Brush tool to paint with sampled pixels from an image or pattern. However, the Healing Brush tool also matches the texture, lighting, transparency, and shading of the sampled pixels to the pixels being healed. As a result, the repaired pixels blend seamlessly into the rest of the image.
Set up the brush size about 20 pixels. Set the sampling point by positioning the pointer over an area of the image and Alt-clicking. Then click or drag in the place where you want to apply sampling point. The sampled pixels are melded with the existing pixels each time you release the mouse button.
It’s very important to leave natural look for the skin so you should have at least leave some small defects. We are going to remove some wrinkles also. When you finish working with Healing Brush Tool you should have something similar to image below.
