Look at your obj tree are things grouped/ Are they in individual pieces etc. Skin and hair are usually seperate unless you choose a specific option on import. Like if I import a poser character as a daz obj. I combine or group by name etc... You may very well have to alter diff parts of skin.From DAZ that shininess would most likely be due to plastic light model. But the key is more in the texture and shaders than lighting.

No need to think outside the box....
    Just make it invisible.
