Acne is treated in a graded manner according to its severity. For example, type one and type two, where the face shows red pimples, acne and some small amounts of pus, can be completely adjusted by Chinese herbal medicine at this time, using methods of clearing lung heat or regulating the spleen and stomach and clearing damp heat. Of course, it can also be combined with topical western medicine at the same time to speed up the treatment. Sometimes it can also be combined with physical therapy, such as red and blue light and intense pulsed light, to improve the effectiveness of the treatment. For Type III and Type IV, called heavy acne, where there are many red inflammatory papules and pustules, and even some nodules, cysts, and scarring, it is often recommended to use both herbal and western medicine at this time. Especially in severe cases, Western medicine can quickly reduce the inflammation. Especially for patients with scarring, it is possible that topical western medicine with high power, such as injectable drugs, may be needed later on to allow the scarring and nodules to disperse. Different treatments are chosen for different degrees of acne.
