Psoriasis, medically known as psoriasis, is an immune-mediated, chronic, relapsing, inflammatory, systemic disease induced by a combination of genetic and environmental factors. There is no drug that makes psoriasis less likely to recur. Risk factors for psoriasis recurrence include patients with hypoproteinemia, family history of psoriasis, bad habits such as smoking and drinking, and psychological factors. The vast majority of patients will relapse after remission, but the disease can be effectively controlled through medication and physical therapy. Currently there is no drug that can make psoriasis less likely to recur. Topical medications such as retinoic acid such as retinoic acid cream, vitamin D3 derivatives such as Calcipotriol, etc. can be used with obvious efficacy, and oral retinoic acid such as Avitamin A. Biological agents such as adalimumab have better efficacy in psoriatic arthritis and moderate-to-severe psoriasis. Physical therapy, such as photochemotherapy (PUVA) and UVB phototherapy, can also relieve lesions. It is recommended that patients with psoriasis go to the hospital in time, follow the doctor’s instructions and actively carry out treatment as soon as possible to avoid delaying the condition.
