Thanks for the photos, and the description. The diagnosis is one of a PWS and you will require multiple treatments. I prefer the pulse dye laser at 595 nm. You will require between 4-10 treatments, note that 10% of PWS are resistant to treatment. See a qualified laser dermatologist for steps forward. In regards to costs, laser in Australia is partially coved by Medicare, and you will reach your threshold after 3 treatments. In Australia, Medicare provides 6 subsidised treatments per year.Once your threshold is reached, treatments are as cheap as $110 USD. Good excuse to move to Oz :)All the best, Dr Davin Lim Laser Dermatologist Australia, BRISBANE
