First get a mask of the face - a binary image that's true where there is face and false elsewhere. Then...
% Extract the individual red, green, and blue color channels using imsplit() (introduced in R2018b).
[redChannel, greenChannel, blueChannel] = imsplit(rgbImage);
meanR = redChannel(faceMask)
meanG = greenChannel(faceMask)
meanB = blueChannel(faceMask)
