In addition to applying medication, facial dermatitis can also be treated with physical therapy (i.e., through instruments), a treatment that not only improves symptoms but also helps to repair the skin. Compared to hormones, it has fewer side effects and has some cosmetic effect. The disadvantage is that it is more expensive and you have to go to the hospital every day on time for treatment. If the symptoms of dermatitis are severe, semiconductor laser treatment is often used. This treatment is well suited for the acute swelling phase of dermatitis; physical therapy can be booked in an outpatient clinic. For acute dermatitis, patients need to visit the hospital daily for semiconductor laser treatment, once a day for five consecutive times; if the treatment is more effective, it can be done once a week in the later stages. The acute inflammatory phase of sunlight dermatitis and cosmetic dermatitis can also be combined with cold spray therapy.
