The KTP laser is used primarily for the treatment of Rosacea. “KTP” stands for Potassium Titanyl Phosphate. The flushing and telangiectasias associated with Rosacea are notoriously difficult to treat with standard medications. Newer technologies, namely medical lasers and light sources, have made it possible to control and improve erythematotelangietatic signs of Rosacea. The KTP laser in particular is an efficacious and safe tool for treatment of this disease.
