Wow, you really go into depth on how you want to lighten those dark spots. That’s great. My best guess for what you want to try next is to apply a gentle, pure shaving soap to those spots. It’s going to probably be less abrasive than anything else you’ve tried, and it’ll be gentle enough that you can get some good absorption with a light scrubbing.  You can just use shaving soap like you normally would. If you decide to add something else, maybe try using a dab of petroleum jelly to the spot for more moisture.  Do you want to see a demonstration of how to use a shaving soap like this?

Why would I use shaving soap? How would that help?
