When one is inspecting and evaluating his or her skin for maximum treatment benefit, it’s best to go beyond the capabilities of the human eye. Underneath the top layer of skin are virtually undetectable imperfections that only an advanced system such as the VISIA system can uncover. Knowing what’s going on below the surface is quite possibly the most important step in choosing the correct procedure. Just as a mechanic wouldn’t fix a car by simply looking at the hood, you shouldn’t get treated until you get a full diagnosis by a trained professional using the VISIA system.
