i say you take a skin texture that is pretty close and then modify it in photoshop. https://www.youtube.com/watch?v=qM9amZJUIok

google skin tones palette and then use the video above to match the skin tone, load all the textures into the same photoshop file and then save each texture individually to avoid any slight variation that would result in a seemline along the texture. the nipples and the lips might require some extra color correction
