Acne nodular hard lumps take about three months to gradually fade away. Nodular hard lumps are a nodule-like change formed during the inflammatory process of inflammatory acne. Patients will have visible subcutaneous nodules when touched by hand, and mild pain may occur when pressure is applied. In this case, if the patient does not take complementary treatment, it will take a very long time for the nodules to subside on their own with their own repair system, and the local skin surface will have a reddish color. If the patient wants the nodules to fade quickly, he or she can choose to use hot towels or apply medications that promote local blood circulation to speed up the fading of the nodules. At the same time, the patient can go to the local dermatology department to irradiate the semiconductor laser, or fire acupuncture treatment to play an auxiliary role. In addition, in daily life, attention should be paid to a light diet, so as not to eat spicy food to stimulate the aggravation of the disease.
