Facial redness/rosacea treatment: Which laser or treatment do you think would be best for my concerns?

Thank you for your question. You are correct that there is no “cure” for rosacea, but the good news is there are effective treatments for keeping the uncomfortable, embarrassing symptoms in check. At my office, we tend to have the greatest success with the Vbeam laser, or intense pulsed light therapy (IPL), which target the vessels of rosacea and also has anti-inflammatory effects.  Photodynamic therapy is also an excellent choice for rosacea. You will likely need a series of treatments at first to achieve an optimal outcome and then regular touch-up sessions to maintain your positive results. Make sure the provider you choose is a board-certified cosmetic dermatologist with the expertise and experience to produce the best possible results for you.

Photodynamic therapy with the blue light is not the best treatment for rosacea, and can make it worse.  PDT is for actinic keratoses which are precancerous lesions that have nothing to do with rosacea.  Most patients are pretty red after PDT and that's probably not the look you are going for.  I would recommend discussing other options with your dermatologist involving lasers for vascular conditions, which include IPL and KTP lasers, also pulsed dye lasers and long pulsed Nd:yag can be helpful.  Please see an expert and buyer beware!
