Rosacea is an inflammatory condition that causes redness and flushing on the face. For some patients, there can be an acne-like pimple eruption. In addition, discrete blood vessels can appear on the face, especially on the nose and central cheeks. A burning sensation is not uncommon.

Over the past five years, there have been significant advances in the way dermatologists treat rosacea. Simple dietary changes are now known to be capable of having a dramatic impact. New topicals are available. Lasers are being used differently than in the past, with better results and minimal to no downtime. When necessary, a low-dose antibiotic can be useful–so low that the pill is no longer efficient at killing bacteria but rather blocks inflammatory pathways that contribute to rosacea.

Dr. Rosenbach designs a personalized treatment regimen for each patient that could include topicals, oral medications or laser treatments. The pulsed dye laser is Dr. Rosenbach’s go to laser for attacking and breaking down the redness of rosacea. These laser treatments are administered every 3-4 weeks for around 8-10 treatments.

Rosacea is a chronic condition. Dr. Rosenbach would say that about a quarter of the patients who request treatment of their rosacea actually have other conditions. For this reason, patients seeking treatment for rosacea are carefully evaluated before treatments are implemented. While there is no cure, Dr. Rosenbach is usually able to achieve considerable improvement.
