Vascular Lesions
Goal - successfully treat unsightly vascular lesions.
These include (but are not limited to):
Angioma - Cherry Angioma
Hemangiomas
Poikiloderma of Civatte
Port Wine Stain Birthmark
Rosacea
Spider Angioma
Telangiectasia (face veins)
Venous Lakes
How - Traditional laser and intense pulsed light systems use light to target Hemoglobin (contained in red blood cells).
Selective Photothermolysis is the process that targets the darker hemoglobin, yet does not harm the surrounding tissue. Basically, the darker colored hemoglobin absorbs more of he light heat energy than the surrounding Lighter color skin tissue. The light energy is absorbed and converted into heat. IF enough heat can be absorbed fast enough , the hemoglobin will coagulate (turn into a solid). In solid form the blood is then able to be filtered up through the layers of the epidermis and is finally removed by the normal process of phagocytosis (dead cell removal).
Many 'salon model ' intense pulsed light systems cannot do effective vascular work because they simply do not generate enough heat energy to coagulate the blood. In fact, many 'professional model ' intense pulsed light systems that do generate the requisite heat, still fail at vascular treatments because they cannot do it fast enough. Many of the existing pulsed light systems require that you pre-cool the skin. This is especially counter-productive when doing vascular work as it constricts / minimizes the target.
