SSS needs to be used carefully. It's not a do-all, be-all solution. When a plugin was first released for Daz Studio to have SSS, the results were mixed. If the effect is too strong, what happens is that the thinner parts of the body like cheeks, lips, nose, ears and fingers all looked like they glowed red from the inside. In the Daz forums, this was described as "lava mouth." The effect needs to be carefully adjusted for the specific lighting in the scene.
