Red marks will appear after the chickenpox heals, and most of them will fade naturally, but the exact time depends on the healing situation. Usually, if no infection occurs, most of the red marks may gradually lighten in color within 1-2 months. Of course, in some cases, if infection or poor healing occurs, the time for the redness to fade may be further prolonged, and even longer can last for about 3-6 months. So in order to promote the fading of the redness, you can apply a local scar removal cream for treatment. For more obvious red marks in daily life, laser irradiation can also be applied in combination, often using 585nm and 595nm wavelengths of lint removal laser. By emitting a certain wavelength of laser light to make the scar within the capillaries to absorb, and then generate heat so that the capillaries are destroyed, thus removing the red marks. In daily life, chickenpox patients should keep the air circulating in the room, drink more water, and also change clothes and blankets regularly to keep the skin clean.
