Thanks for the photo.
No big deal.
Leather has to be cleaned with leather cleaner to remove dirt and old contaminations. Scratches and little gaps can be filled with a special fluidleather. When it is dried the leather has to be carefully sanded with light "sanding pad" to flatten the leather surface and make it plain and smooth (not sandpaper!). Than the leather has to be dyed with a color that matches your leather color exactly. Finally the leather will be sealed with a leather fat.
Here is a good desciption which also contains videos:
