How often does it happen that one would require more than one Halo Fractional treatment to get a positive result? (photos)

Thanks for the great question and the photos. I also combine BBL with Halo pretty routinely in my practice. I think that it maximizes the reduction of the brown pigment in the skin. Looking at your photos, you will definitely get an improvement with a single treatment, but you will likely require a couple of treatments for most of the pigment to be gone. An aggressive treatment often times means that the laser will be treating a higher percentage of the skin at a great depth. You are a good candidate for a more aggressive treatment. Best of luck!~Dr. Sieber

Great question - you are an ideal candidate for Halo treatment! In our office, we always combine BBL (Broad Band Light) with our Halo treatments. It doesn't add anything to the downtime, but you get much more improvement in browns, reds and antiaging than you would with Halo alone.
Halo can be done in a wide range of intensities from very light to quite strong. The lighter the treatment, the more you will need. Also, it takes less treatments to improve color (brown and red) than if you are looking for a lot of texture (wrinkles, lift and pores). You should see some improvement with any treatment, but given the damage you're starting with, your best results would be with 1-2 very strong treatments, or a bigger series of light-moderate ones.
