leather protection

I have beige leather seats in my 2016 s, and drivers seat color started appealing, was wandering if anyone can recommend products to stop this appealing and even repair it if there's any coloring products. Also what you use to keep leather in good condition?

Wanted to share the protective car seat cover I purchased to guard the leather from my child booster seats. Bought 2 sets of both Royal Oxford and Diono. Not only is the Diono of better quality and craftsmanship, its larger covering more surface area.
