I am East Asian and I am looking to increase the height of my nose bridge. Would you recommend a PDO thread lift or fillers? From what I understand, (1) a greater height can be achieved using PDO threads, (2) there is less chance of migration of the product, and (3) there is a reduced risk of blindness and necrosis. What are the downsides of a PDO thread lift (asides from the higher cost)? Can it still lead to blindness (I assume not as there is no substance entering the arteries)?
