IPL/BBL versus Vbeam for flushing and permanent redness from Rosacea.

Sorry to hear you are dealing with Rosacea, but the great news is that it is very controllable, particularly in your skin type. Based on a lot of research in this area, and me, the doctor, suffering from Rosacea myself, we have made this a specialty of the office.
Many patients with Rosacea benefit from topical or oral antibiotics with antiinflammatory properties as well as an antiinflammatory diet. After much research, I have chosen BBL as the technology I want for myself and my patients. Although in our office, most lights and lasers are performed by me, the physician, that is unusual. Usually a nurse, tech or aesthetician does most offices lasers. BBL is Sciton's brand name for it's version of IPL. Although a much more expensive machine for the doctor to buy, I chose it due to its greater power and also better precision and finesse. It is the only device with research from Stanford to support anti aging benefits and with proper settings, improves reds, Browns, collagen production, Rosacea, overall l brightness of the skin and should not remove any abnormal pigment. It is a workhorse in my office and between my Rosacea and having to have my skin look its best, I do it 4-6 times a year, every year.

Great question! First of all, BBL is the same as IPL. BBL is just a brand name of one IPL device. The laser companies are always trying to become a brand name, like Kleenex or Xerox, but it is hard for them because there are so many devices that are all similar. BBL happens to be an expensive one.
Without pictures, it is hard to give you a firm answer to your second question, but if you have pale skin with mild rosacea, you are probably a great candidate for IPL or a vascular laser like V-beam. Most of us do not have vascular lasers-- they do one thing well, but they're much less versatile than IPL and much more expensive. So we do a lot with IPL. 
Lets clear something up here: Lasers and IPL have a target (or chromophore). We most often talk about "pigment" or "redness" as the targets, but there are others. For you, the target is redness or dilated vessels. "Pigment" generally refers not to redness but brown pigment or melanin in the skin. Lasers that target pigment cannot distinguish between a sun spot and a tan. They all work best when you have light skin. The darker your skin, the more trouble you can get into trying to treat pigment. You'll see many pictures on this site of people who were trying to get rid of brown spots and lightened the entire treatment area. If you are treating redness with IPL, it will also target brown pigment-- something the Vascular lasers do much much less. So, people who have medium or dark skin should definitely seek out a vascular laser for redness. But if you have light skin, IPL is a great tool.
I hope that helps!
