What Can I Do to Minimize Potential Hyperpigmentation by Vbeam?

Thank you for your question.  I don't think you will need the Vaseline, and depending on your skin type, the risk of pigmentation is really low if you are not too dark in skin color.  Have a test spot done first, and talk with your provider about pretreatment with Hydroquinone and Retin-A.

I hope this helps.

The V beam laser works great for treating spider veins or red areas on the face.  The most important thing you can do to avoid any hyperpigmentation from the treatment is to make sure your skin is not tanned or sun burned.  You want your skin to be your lightest normal color.  I would try to avoid sun to your face as much as possible before the treatment and be sure to wear sunscreen.  

If you have a light skin type, it is unlikely that you have to worry about hyperpigmentation following vbeam.  Nevertheless, strict sun avoidance just prior to and following the vbeam procedure, making sure your skin is not tanned is the best thing to do to prevent any hyperpigmentation.  Remember to use a good physical sun block following treatment as well.
