I don't think you should do this. Waxing/epilating irritates your skin and applying peroxide (I'm assuming a commercial solution of hydrogen peroxide) can be damaging to the skin, doing it right after epilating is bad, you can damage your skin. Alcohol is not much of a problem, it is used in aftershave stuff, because it can actually help your skin heal as it is an antiseptic, but it will also make your skin dryer long term. Over all, this will probably not have the results you are after.
