These are easily treated with Pulsed Dye laser. Typically this requires 3-4 visits. While some lasers don’t produce a lot of bruising, my impression is that the ones that bruise require fewer treatments to get done. I have two different pulse dye lasers and use them frequently. When people have lighter vessels, I use my intense pulsed light to help get rid of them. This is nice because there is usually no bruising.
