Should I get V-Beam or use a lightening cream for this scar? (Photos)

My scar is darker than the surrounding skin. It's been like that for quite some time now from when I was very young and had a large cyst that resulted in this. Scar used to be a hypertrophic scar that is now flat. It is on my upper arm. I would like to look at ways to lighten the scar so it can match my skin. I'm not sure if it's this color because of hyper vascularity or due to hyperpigmentation. Any creams that I can use to make the skin blend in?
