What should I do if my skin is severely dehydrated? I think we should look at this problem from two aspects. First of all, if the skin is severely dehydrated, we definitely need to hydrate the skin. But the choice of hydration methods is certainly dazzling. Because of the various treatments and improved products on the market are blown out of proportion. But is it effective? We need to put a question mark. As a dermatologist, I recommend a treatment for readers with dehydrated skin, and it is hydration injections. How does hydration injection hydrate? The specialized hydration injections in medical facilities are done by injecting our water locking substance hyaluronic acid directly into the superficial layer of the dermis. Then let hyaluronic acid to help us hydrate. Secondly, for skin dehydration, we also need to focus on moisturizing. No matter how much water you inject into the skin. If you do not moisturize, the water in the skin is not retained, like a hurried passerby, immediately metabolized to the air with the body’s activities. If you can’t figure out how to imagine your skin as a straw, when we cut open a straw that has just drunk water, it must have a lot of water. But put on a while, the moisture will follow the air and run away. If we do not wrap a layer of cling film on the surface of the skin, it will lose a lot of moisture very quickly. Therefore, we must treat skin dehydration with a two-pronged approach. The first is to inject water into the skin, and then to repair the skin barrier, so that the skin’s cling film can be able to store the moisture inherent in the skin, only then can the problem of skin dehydration be completely solved.
