The red blood, i.e. capillary dilatation, can be improved by general treatment and physical therapy. 1. General treatment: For patients with capillary dilatation, they need to pay attention to skin care in daily life, avoiding the skin being stimulated by too cold or too hot. Usually travel also need to do a good job of sun protection, such as wearing a sun hat, umbrellas, etc., to avoid prolonged exposure to the sun, in order to prevent the aggravation of the disease. 2. Physical therapy: laser therapy is one of the common physical therapy methods for capillary dilatation, including dye laser, intense pulsed light, etc., which can play a role in destroying the abnormal capillary dilatation, and help to improve the capillary dilatation. There is no single way to improve capillary dilatation, so it is recommended that patients go to regular hospitals and cooperate with doctors to carry out standardized treatment.
