In medicine, redness refers to capillary dilatation. Due to individual differences, there is no good way to remove capillary dilatation, but it can be improved through physical therapy and general treatment. 1. Physical therapy: For patients with capillary dilatation, photoelectric treatment can be taken, using high-energy laser to denature hemoglobin, thus destroying and blocking capillaries, thus improving skin symptoms. Common lasers are photorejuvenation, dye laser and so on. 2. General treatment: For patients with capillary dilatation, they should avoid prolonged exposure to the sun and avoid excessive cold or hot stimuli. Usually, you can use more gentle skin care products to prevent damage to the skin barrier. Improvement of skin capillary dilatation is not a method, it is recommended that patients go to a regular hospital, with the doctor for standardized treatment.
