I have a over 2 years old pink scar on my nose bridge to Dorsal. I was told it is telangiectasia and that RadioFrequency/IPL (Pulsed Light) Radiofrequency (RF) will help. How dangerous is this? What are the side effects? Pulse dye laser and BBl has not helped. Is RadioFrequency/IPL (Pulsed Light) Radiofrequency (RF) safe? Are there other options?
