Both of the images attached have the issue. 

Hi Damien,
I was hoping you could help me identify what is causing the weird pinkish blotchy texture/colouration in my images when I use the paintbrush tool to soften my backgrounds. I can't always see it when editing on my mac, but then when I upload the image to Facebook it is very obvious. I have added 2 seperate images with the same issue.
