Hi C.,
I have seen a lot of client with the same problem. What I usually tell them is stop the shaving first! Start waxing! This will help your skin a lot!
As far as home remedies, there are a lot of whitening treatments that you can use at home, but I'm not sure how efficient or safe they are. I would find a local medical spa near your home, they will be able to help you! I usually do chemical peels on my clients to solve the problem, and have seen some satisfying results! Hope this helps!
