This WILL ruin your headlights! It works because it chemically strips a portion of the plastic, plus it adds a layer of oils to them, as well as micro melting them. It can also damage surrounding paint.
Oxidation needs to be removed manually by polishing and sanding, then reprotected with a sealer or coating.
I'm a professional detailer, full disclosure. You can do this with one of the kits, then buy some sealer, but in most cases, dropping by (or getting it done mobile) a qualified detailer is the best way, and will run you less than $100. It will last longer than the factory with much better results.
Please don't put off, wd40, or any other quick fix crap on your expensive lenses.
I just replaced a set of $1500 Lexus lenses because my friend did this to hers.
Here's a video with a bit more explanation.
I hope this helps someone.
