Both HSI and YCbCr are based on the idea of separating the brightness component from the color component.

I in HSI is (roughly) the equivalent of Y in YCbCr. H and S in HSI is (roughly) a polar representation of Cb, Cr in YCbCr. For the exact difference check the formulas.

It might be a bit more convenient for you to work in polar coordinates (HSI), since skin tone is located in a specific H range.
