1. Washing with hot water and scrubbing with soap are contraindicated in the acute stage. Strongly irritating topical drugs are prohibited. Clinically, we see many cases where the course of the disease is prolonged or the disease becomes allergic dermatitis due to insufficient attention to general treatment.

2. Antihistamine drugs

Antihistamine drugs can be appropriately used, such as chlorpheniramine, cyproheptadine, terfenadine and graminone, etc. Vitamin C can also be used .

3. Ultraviolet irradiation

After the acute inflammation period has passed, the use of ultraviolet spot irradiation can promote the regression of damage.

4. External application of medication

Lugangu lotion can be used for external application.

Mild cases have no subjective symptoms, and the course of the disease is self-limiting. It does not require treatment and may subside on its own. During the acute attack period, all kinds of stimulation and moisture should be avoided. The purpose of treatment is to relieve symptoms and shorten the course of the disease. But the exact effectiveness of some treatments is difficult to evaluate.
