Whether capillary dilation can heal itself depends on whether the capillary dilation is primary or secondary, and generally the former cannot heal itself, while the latter has the possibility of healing itself. 1, primary capillary dilation: capillary dilation due to congenital or genetic factors usually cannot heal itself, and needs to be improved with clinical treatment, which can eliminate the locally dilated capillaries and thus achieve the purpose of healing. Common treatment methods include laser treatment, cryotherapy, high-frequency electric knife treatment, isotope radiation therapy, etc.; 2, secondary capillary dilation: for secondary capillary dilation caused by long-term sun exposure, ultraviolet radiation, etc., in the early stage of symptoms, through sun protection, face ice, etc., can make capillary dilation self-healing; secondary capillary dilation due to the use of hormonal drugs, after stopping the drug can The secondary capillary dilation caused by the use of hormonal drugs can be cured by itself after stopping the drugs. For secondary capillary dilation with longer onset time, the capillary dilation is persistent and the contraction and diastolic function is irreversible, so it usually cannot heal by itself. Patients usually need to pay attention to skin care, such as the stimulation of temperature changes, excessive sun exposure to make the capillary tolerance exceed the normal range, causing capillary dilation.
