OK it is zit cream. I just use Walmart Equate brand because zit cream is kind of expensive for some reason. I just use a frayed ended wooden toothpick to apply, because I want the line to be only as wide as the ink line. You want it on thick enough that you can't see the ink through it. Then you set it in the sunlight outside. I guess it is a combination of the UV rays and the chemicals in the zit cream. Bring your purse in when the sun goes down and wipe it off with a damp rag. If you can still see any ink repeat the process until the ink is gone.
This works on suede also. BUT, I have to mention I have only used this method on the white or creamy colored bags like I have pictured above. The picture above only took one time. It works on black and blue ball pen and permanent marker type inks. I am currently trying it on red and have it at a very light pink right now, so red seems to be tougher.
I think if you guys want to give it a shot, I would recommend trying it on the inside leather first because it is a bleaching process. I haven't tried it on brown or any other colors of leather YET. But I will eventually try it on a non Coach first.
Let me know if you give it a shot and how it works for you!
I love how it says "vanishing formula" on the box.
