Vaseline is just a barrier that keeps moisture from escaping, it’s called an occlusive. I would suggest using virgin coconut oil, shea butter or cocoa butter and having him wear Nitrile or vinyl gloves, latex will break down. Those 3 oils are an occlusive that have natural moisturizing and healing properties. Think of it as lip balm for your body.
Ah yes, the famous classical painting titled “Drunk stripper falls over.”
