Mod The Sims has a tone of good skins/eyes. http://www.modthesims.info/download.php?t=398421
for realistic skin.http://www.modthesims.info/download.php?t=287488
for realistic eyes. I used to use these eyes until I switched to Nouk's (great creator, by the way) eyes. http://www.modthesims.info/download.php?t=354309
there are also these eyes by dragonmandy.
I think Mandy (dragonmandy) is without a doubt one of the best creators for realism. She for the most part does eyes and makeup, and has some hair. She's one of my favourite creators, so I would recommend checking out her stuff at http://www.modthesims.info/member.php?u=1051765
Happy Simming! (I use dragonmandy and Nouk's stuff to make my Sims look more realistic)
