matters needing attention

Here, I would like to remind you that scratching can make the skin continuously subject to mechanical stimulation and become thicker, and even cause infection. Scratching also plays a strengthening role. The more patients scratch, the more itchy they are. The more itchy they are, the more they scratch. A vicious circle is formed and the course of disease is prolonged. In particular, alkaline soap is a kind of chemical stimulation to skin, which can aggravate dermatitis and eczema. If you need soap decontamination, it is best to choose less irritating boric acid soap.
