Test the product on a small area for a color match - most manufacturers supply a toner to alter the color if needed. If your satisfied with your test area, apply the product per the manufactures recommendations - usually with a spray gun, a soft bristled brush or by a sponge; we prefer the latter.
For creases and cracks, dilute the product with 30% water and rub it onto the leather. Let it dry for about a minute and then wipe with a damp cloth. The product will come off good leather, but will remain in the creases and cracks.
