The husband asked, "Do you use azelaic acid to cleanse your face?"

On the other hand, he said: "Azelaic acid is mild in nature and has no risk of breakouts. It has antibacterial and anti-inflammatory properties, and can regulate the keratin, so it is rare for the skin to break out due to it. However, people's skin is different, or there are sensitive people. When using it for the first time, there is occasional discomfort, or the appearance of breakouts may appear. However, over time, the skin adapts, and this phenomenon will disappear. If the breakout is obvious, suspend use, seek medical treatment, and determine the treatment method for the reason."
