I'm sorry that you don't like your freckles, most people really do find them charming, but I guess you don't;
I've never treated freckles before but I know of a recipe thst is proported to work, it is based on the plant Broom, and if you like I could make some up for you as I happen to be surrounded by lots of lovely wild Broom.
I can't promise that it will work, but it mmay be worth a try.
