Turned up some of the lights and area light was moved closer on the right hand side. This made render times go up significantly.

Disabled all spot and area lights, just have IBL turned on.
Whats interesting here, is the detail in the skin is lost and seems more "grainy" regarding to light. Im guessing its due to IBL being used as an environment light and not having enough samples per pixel to create a higher definition. Interesting. Clearly you need to have spot, area lights in the scene.

Here you can see grain even though render quality set to 100%. KEEP THIS IN MIND!!
