Get a bottle of quality silicone lubricant, the best you can find.
I buy wet platinum and use it for everything. My 4 years old leather jacket still looks like new, and so do my sofa-bed and chairs. It is also good if you have good quality leather seats in your car, it keeps them soft like when the car was new out of the dealership.
And of course it was intended for the skin in the first place, so it's a wonderful moisturizer if you have allergies and cannot use lotions. Seriously, I buy giant bottles of the stuff, and haven't purchased a tub of lotion in years. It is especially good for your hands when you have to wash your hands a million times a day at work!
