Photon skin rejuvenation and photon skin rejuvenation treatment of red blood filaments are also based on selective photothermal reaction. The light used by photons to remove blood filaments contains wavelengths that are strongly absorbed by hemoglobin. When hemoglobin strongly absorbs light energy, it will It is converted into heat energy to heat the entire blood vessel, causing it to coagulate and become necrotic, and is finally absorbed by the human body to achieve the purpose of treating bloodshot eyes. After photon treatment, the blood streaks are removed and the diseased capillaries are eliminated, so there is no possibility of recurrence. From this perspective, photon removal of red blood lines is permanent and will not rebound.
