Odd Skyrim skin glitch

[MrSangurch]

So, i've downloaded a few mods recently that add some minor NPCs to the game (Dawnguard city guards, Bandits for a modded dungeon, etc.) The problem being is that the texture of their skin appears multi-colored and pixelated, not at all what it should be. So i was wondering whether this is an issue with the mod, or if something else is causing this, and if there is some kind of work around.
