Wel, it depends. If the magic sort've 'keeps the skin going' for a while, he may not need to trade off That Often.
If all it does is let him wear the skin, then yeah. But I'mt hinking it allows him to sort've 'feel' alive; get the person's senses of touch and taste briefly. Though after a while, those go too, like it's slowly dieing and shutting down.
Of course, there's always 'Grim Repose'.
