Red nose corresponds to rosacea in Western medicine. In clinical treatment, the first thing to do is to get tested for mites. If the test is positive for mites, you can choose to apply clindamycin metronidazole and apply metronidazole tablets for mite removal. If the effect is not significantly improved, you can add isotretinoin and use pulsed dye laser or intense pulsed light treatment, avoid alcohol and pay attention to sun protection during the treatment period.
