If you mean something to the effect of pores on the skin, I have a fantastic way to achieve the pore look.
It's simple, after you have completed and set your veins, the next layer would typically be the layer in which you would create your pores. Mix up your skin color and make a pretty thin consistancy. Then, brush on the skin mixture and pounce it with a sponge. Try not to pounce the same area too much or you will smooth out the texture. Do this on each limb and the head and that should cover it! I hope this helped. This may not be the way everyone does this, but it's the way that I do it and it works great for me =)
Another skin texture is fine baby hair on the face. To achieve this you would use the same directions for the skin mixture and paint it on with a mop brush. and it should give the effect of fine baby "peach fuzz."
