![]() ![]() Fluences were selected by the treating physician based on extensive experience with earlier generation PDLs, and observation of tissue responses during laser treatment. ![]() Then diffuse redness was treated over the entire face with a 15 mm diameter circular beam, a pulse‐duration of 3 ms, and increasing average fluences over the four treatments starting at 6.25 J/cm 2 for the first treatment and averaging 6.97 J/cm 2 for the final treatment (Table (Table1). Linear vessels were first treated using a 3 × 10 mm elliptical spot at a fluence of 15 J/cm 2 and a 40 ms pulse duration. All treatments were administered and visualized by the investigator using a cross‐ and parallel‐polarizing head lamp (v900 Syris Scientific, Gray, ME). Of the 19 subjects, 17 received the maximum four laser treatments with a 1 month interval between treatments, while two subjects missed a single treatment and had just three treatments due to scheduling difficulties. The improved efficiency of this new PDL enables delivery of higher fluences, and/or much larger beam diameters than were previously available, as well as longer dye life than currently‐available PDLs.Īll subjects received full‐face treatments with the novel PDL (V‐Beam Prima, Syneron‐Candela). In this study, we investigate the safety and effectiveness of treating rosacea using a novel pulsed dye laser (PDL). Vascular‐targeting lasers are a mainstay for treating superficial skin vessels, which are the root‐cause of the flushing and blushing that characterize rosacea. Whatever the true numbers, rosacea is a very common disorder, caused in very large part by chronic sun‐exposure. ![]() Another study directly examining people for rosacea, and not depending upon historical data, found 10% of those examined had rosacea in one community, with women having a higher prevalence (14%) than men (5%) 8. Rosacea prevalence ranges widely from 1% to 22% depending upon the population and the means of surveying various populations, with one study demonstrating a prevalence of 9.6% in a diverse population, and 16% in a more focused study of Caucasian women 7. Subjects may also present with facial stinging and burning, ocular symptoms, and hypertrophy of nasal sebaceous glands, termed rhinophyma 2, 4. Rosacea is characterized by facial redness, spider veins, flushing in response to numerous stimuli, and papules and/or pustules. This would implicate UVA as having a significant impact on developing rosacea, because window glass blocks virtually all UVB. The main culprit in causing rosacea is sun‐exposure as evidenced by the predominance of photodamage, including facial redness and telangiectasias, on the side of the face adjacent to the car window for drivers and passengers, which varies by country 5, 6. Numerous stimuli cause these extra blood vessels that occur due to chronic sun‐exposure to temporarily dilate, including: hot, cold, exercise, sunlight, coffee, alcoholic beverages, and many other common aspects of normal life 1, 2, 3, 4. Rosacea results from chronic sun‐exposure and is more commonly seen in lightly pigmented individuals who are genetically susceptible to develop diffuse redness, telangiectasias, and/or papules and pustules in response to chronic sun‐exposure.
