HID’s causing Headlamp oxidation?

My plastic headlamps tend to slightly oxidize after a few years from the sunlight, I have given them a couple of hard polishes since I have owned my car, which cleans the outside oxidation up.

But now I'm wanting to convert my headlights to HID with projectors. Do HID's cause oxidation in headlamps? If yes, is the oxidation on both sides of the plastic (inside & out)? Meaning you will have to replace the headlamps as you can't polish the inside layer clean.
