Colour change on my model

After taking my photos and loading them on to the computer I noticed that my model had some small imperfections on her skin such as a red nose and lighter patches of skin on her forehead where her makeup had rubbed off. To fix this I created a new layer and then used the colour tool and picked up the colour of her skin around the imperfection, I then coloured over the imperfection trying to follow the natural curves of her face. This will make the colour look better but will not blend very well into her natural skin, so I changed the opacity on the layer that I coloured in until I was satisfied with it. I then took the blur and smudge tools and gently dragged the original skin and the colour placed on top until it looked natural. I done this technique on her nose and also the high points of her face where her skin looked patchy.
