Usually you don't 'add' skin texture. When you retouch, you shouldn't remove it in the first place.

Use the dodge and burn method (there's a RetouchPRO tutorial available),
or use one of the noise reduction plugins that won't eliminate all texture.
Try Portraiture, it does a nice job when you don't need a high end retouch.

to add skin texture is to add the skin texture on a new layer, blendmode linear light, the use high pass filter and adjust radius until the skin texture "fits"...I tend to take down opacity as well! hope this helps!
