you could easily just use a good concealer. They have ones formulated to cover tattoos like DermaBlend and such. I used concealer when I had my maternity pics done and I wanted to cover up that dark line.

And yes Dragonfly, I think it is usually women who get it, which is why I'm trying to find what the best treatment is for someone who was born with it.
If you have some kind of hyperpigmentation, your doctor will most likely prescribe hydroquinone and/or Retin A.
Why not go to your doctor and make sure you have something harmless like linea negra and not something else more serious. And then the doctor can prescribe the right mediations.
