Hey Kate, No high or low profile means where they are going to place the implant. I’ve had the inspira soft touch implants, they are suppose to have more shell layers and feel more natural and they are suppose to have a less chance of rippling/rupture. The CUI ones are also very good, the soft touch are just the next ones up. Most surgeons are more than happy with the CUI’s. I went for the soft touch cus im only 24 so i wanted piece of mind of knowing i’d picked the best i can at the time. I paid £461 extra and as far as i no all surgeons will use them if u ask xxx
