Facial mask is absolutely necessary for girls nowadays, as a magic weapon for skin moisturizing. However, if the mask is used improperly, it will not moisturize but hurt the face.
Recently, in order to make her skin moist and young, Ms. Liu in Shenzhen has to apply the moisturizing mask twice a day. Unexpectedly, I have used countless products, but the skin on my face is not moisturized, but it is getting drier and drier, sometimes it turns red and itchy for no reason.
The doctor said that many patients have facial skin problems in clinic, and they feel that they need to replenish water, but their way is often to spray all day long, or apply mask every day, which is actually wrong. "Excessive hydration will also weaken the skin barrier, which will easily lead to skin sensitivity."
Seeing this, I was frightened by Xiao Bian who had just applied the mask. So, under what circumstances will sensitive skin be caused? How to prevent it? Come and have a look with Xiao Bian!
