On the one hand, we say that psoriasis is not an incurable disease; but on the other hand, it must also be admitted that no cure has been found yet. Some patients with psoriasis have not relapsed after treatment, but this does not mean that the root is broken. Because psoriasis is genetically determined, and it is still not possible to treat psoriasis genetically, it is not possible to talk about a cure. At present, it is believed that psoriasis is determined by several genes and environmental factors, and environmental factors are also one of the determining factors. Therefore, we can prevent the expression of psoriasis genes and cause disease by preventing and controlling infections, avoiding wet and cold stimulation, maintaining good living habits and psychological state and other environmental factors. Do not easily believe in false propaganda of newspapers and broadcasts about curing psoriasis.
