Conditioner that doesn’t darken leather?

Is it possible to have a leather conditioner that doesn’t darken leather? I bought these beautiful boots and I’m reluctant to condition them because I don’t want to lose the variation in colour.

Bicks or Leather CPR.

I’ll look into those - thanks!

Bick 4, or Effax Leder Balsam. I prefer the latter for non-darkening conditioners.

Thanks! I’ll look into those.
