https://www.nubwaybeauty.com/products/high-frequency-spider-vein-removal-machine/ High Frequency Spider Vein Removal Machine Nubway thread vein removal machine uses high-frequency painless treatment to transmit the released energy to the lower surface of the skin to remove the diseased capillaries. The hemoglobin fragments are then broken into small molecular clusters that can be absorbed by the tissue. Due to the repair and regeneration of the skin, after being absorbed by the tissue, the space for the broken hemoglobin and capillaries will be replaced by new skin tissue. If red blood streaks are treated with this technique, they will not rebound for life.
