Quinlor, glad you got something out of the tut. Fresnel Effect....well at one point I had this theory that light reflected a different colour based on the angle it hit the skin (almost like the skin cells bounced back white light straight out, and red light if it hit the side of the cell. If you had a look at any photo taken with a flash, you'll see all the 45 degree skin surfaces are red, and the facing skin is white. So it all sort of made sense and I implemented the fresnel effect. Then I got more into sss and realised that's what was causing the redness, so I removed the fresnel effect, implemented the incident effect, but the renders still lacked a little something. So I added the fresnel again! The fresnel is almost impossible to see, but you notice it if it's not there.
