The appearance of spider-like capillaries is one of the signs time leaves on our skin. They may be found anywhere on our body surface, but usually bother us most when found on our face.
Telangiectasia, or broken capillaries get their color from clotted RBC (Red Blood Cells).
These capillaries can be seen and get their color due to weakness of the one-way valves found in the veins. Once the valves are weak, vein blood with little oxygen can stay in the capillarie instead of being pumped to the heart. Since these capillaries are very narrow, blood cells may get "stuck" in them.

Two treatments are administered in order to treat the capillaries:
