Redness, or capillary dilatation, can be removed by laser.
Capillary dilatation is due to the weakening of the elasticity of the capillaries and the increase in brittleness, resulting in the continuous expansion and rupture of blood vessels. Capillary dilatation is commonly treated with laser, the principle of which is to remove capillary dilatation by applying light and heat, acting on the hemoglobin in the microvessels, causing the superficial capillaries to form a closure and be phagocytosed by the macrophages in the human body.
Capillary dilatation can also be treated with photons, the hemoglobin in the deep blood vessels absorbs the heat of the photons and passes to the vascular endothelial cells, which will undergo photocoagulation, destroying the blood vessel wall in order to achieve the purpose of treating capillary dilatation.
If capillary dilatation is caused by hemangioma, vascular nevus, angiokeratoma and other diseases, the primary disease should be actively treated, and the capillary dilatation can be relieved after removing the cause of the disease.
When capillary dilatation occurs, it is necessary to go to the hospital in time to find out the cause of the disease and treat the symptoms under the guidance of the doctor.
