1. You could try to increase Vitamin E content. So any foods with healthy Fat in, or somerthing like Cucumber.
2. Drink more water possibly.
3. Use something like Cocoa Butter.
4. Try a product like Bio-oil.
5. Live with it and accept it's better than having doo dah, that isn't fit for much except chronically slow peeing.
I'm not speaking from experience by that, before anyone gets the urge to take that comment further
