How to heal years of damage due to picking the palms of my hand?

Hi all, So I've been picking the skin on the palm of my hand for about 5 years now. I pick and pick and pick till it bleeds. I've finally figured out a way to manage it. Moisturizing gloves and lots of hand cream! You must wear them as much as possible! I've come a long way the past 3 weeks...finally there not much there to pick. But- the skin is still rough, red, raised and hard :( Can anyone recommend anything to help the healing proccess? I've used, shea butter, vaseline, polysporin, regular hand cream, spectro e-care cream, vitamin e, aloe vera gel.... Will the skin ever be normal again?! I'm getting slightly discouraged. Any advice is appreciated.
