I have been shaving my pubic area for almost 2 years now and I'm just noticing that my pubic area seems dark. I use an electric razor and sometimes I get razor bumps or it gets itchy. I've used petroleum jelly a couple times and hydrocortozone once to prevent bumps/itch. Since I've only done it a couple of times I don't think that's the cause, but is there anything I can do to make it brighter?
