Haven't used leatherique myself but seen the results on a friend's Beemer. Was impressed. It's the best DIY leather restoration you're going to find. If you don't want to mess with that you can always go with a pro and get a quote from an upholstery shop.
Simple do it yourself solution. Take a sample of dash item or anything that matches the seat color to Home Depot and have them match the color in a sample size bottle ($6 or so) of premium interior latex paint.
Clean the area to be redone and brush the paint on a small area. Let it sit for about a minute and then wipe it off with a paper towel. All the creases will fill with the paint and also leave a small film on top. You can experiment with more layers of time to leave on before wiping off. Buff with cloth when dry.
I know this sound crazy, but I do it on my LS430. It almost exactly what an upholstery shop will do if you ask them to redye the panel. It doesn't peal and flake off, but it will wear off in a few months. Then just repaint.
