Firstly, I copy the one layer from background named blemish for preparation. Then use the spot healing brush tool to remove obvious blemish on the skin. Secondly, To make the skin more smooth, we also should creat the two copies of the blemish layer and rename it as skin tone and details separately. Use the gauss blur to remove the texture on the skin tone layer and use then use the ‘apply image option’ to subtract the color of skin tone from details layer. Adjust detail layer to linear light to make the image can display normally. Use the lasso tools to select the area you think should be more smooth and use the gauss blur tool to blur them.Thirdly, Create a new copy of skin tone and use the dodge and burn to adjust the portrait as you want. Lastly, To enhance the eyes, create a lightness and contrast layer and improve the brightness of whole portrait. Then use the brush with black but white ground to cover the whole picture except pupil.
