Is psoriasis harmful to phototherapy?

Hello! Psoriasis phototherapy belongs to physical therapy, and the treatment principle is to prevent and treat diseases by using sunlight, visible light and invisible light in artificial light sources. Ultraviolet irradiation can improve the symptoms of psoriasis in a short time and filter out harmful ultraviolet rays, which is mainly used to treat systemic or local intractable psoriasis.

Suggestion: Although phototherapy is effective in the treatment of psoriasis, it has great side effects and cannot achieve the therapeutic effect fundamentally. Common are stomach upset and itchy skin. Long-term use will increase the chances of spots, premature aging and cataracts on the skin. Moreover, many surveys of patients who have received phototherapy for a long time show that long-term use of phototherapy may induce skin aging and skin cancer, and it is not recommended for patients to use phototherapy.
