How do you knock down the over glossy skin?

I have some figures where the skin is just too glossy. So much so it make the figure look sweaty or wet. So how do I tone this down?

Surface panel glossy and relativity sliders.

There are several ways to decrease the skin gloss, but basically, you need to adjust the skin settings. Here's some tips...

Adjust Skin Settings (and Remove Glossy Skin/Shiny Skin):
NOTE: Some parameters only show under certain settings, such as types of Base Mixing, etc.
1. Select G8F figure in scene tab
2. Open your G8F figure in the Surfaces tab (twirly arrow)
3. Select: "Skin-Lips-Nails"

Next, adjust the following surface parameter sliders:
Dual Lobe Specular Weight: Reduce or turn-off to eliminate shiny skin shine
Glossy Roughness = 0.5 = Default (increase roughness to remove shiny skin by making it more dull)
Glossy Layered Weight = Lower if skin or cotton clothes are too glossy (around 0.5 - 0.0 would be non-glossy)
Metallicity: Reduce for less glossy skin
Reflectivity: Reduce for less glossy skin

Optional Surface Settings:
Set Base Color Effect: Change from Scatter & Transmit to Scatter only for less shine
Backscattering Roughness: Reduce for less sheen
Top Coat Weight: Reduce for less specular surface reflection
Glossiness: Reduce for less highlights and less shiny surface

Alternately, you can try a product in the Daz store, such as Ultimate Iray Skin Manager:

It depends a bit on how the skin is set up, but generally speaking you want to increase parameters that include the word "roughness".

It depends on the surface.  Daz figures have used different types of skin shaders, and different PAs using the same shader will make adjustments to different sliders, so those excessive glossy effects can come from different surface settings on the same shader type.  There really isn't any substitute to actually going to the "Edit" panel of the "Surfaces" tab, making adjustments with different sliders/values, and making a 30-second test render in your preferred lighting conditions and render settings.  Assuming you're working with a relatively new character with an Iray shader, I'd begin by adjusting "Glossy Reflectivity" to a lower level.  I almost never touch any "Roughness" settings--They can reduce the glossy appearance, but I find that the reduction comes with unwanted side effects.  Sorry, but there's no short answer that will be absolutely correct for every user with every model in all lighting conditions and render settings.  It's trial-and-error, but the adjustments involve less error with practice.

[This is a clear instance of how a chapter about editing surfaces in a proper manual would be so useful.]

I would toss him a towel  . . . or use curves in photoshop for a matte finish.
