That's right. The brand concept of medical skin care is relatively new. I have contacted them with a grain of salt before and found that they are really professional. My skin was allergic before, and I used ointment. Later, it was red and itchy for a while. I always thought it was an allergen. I went to our Qingyuan Hospital for examination, which showed that I was allergic to essence and pollen. But then after taking a shower, my skin was red and itchy. This is really painful, and I don't know what to do. I accidentally saw the ocean from the Internet, so I searched it on WeChat and contacted it. That was the first time I knew that skin was a barrier function. I told my teacher about my skin care process and habits, and the teacher corrected my problems one by one. Although I don't believe it, there is no other way. I tried it and followed the instructions. Take a facial cleanser as an example. The teacher always tells me for a long time. Sometimes I hate her wordiness, hahaha, behind.
