How about
rgbImage(:,:,3) = 0; % Remove all blue components from every pixel.
Otherwise, attach your image (like most other people who want image processing advice do) and explain what you mean.

Explain in detail what "remove" means to you, keeping in mind that images must remain rectangular, not have irregular "holes" in them. Do you want to make it all solid, pure black? Do you want it to have the same coloration as the lighter skin? Why do you need to remove it anyway? It looks like you probably are interested in the dark melanin regions so why can't you just find the blue and ignore it? Have you tried the Color Thresholder app on the Apps tab or the tool ribbon? If not, why not?
