In daily outpatient clinics, we often encounter patients who, because of their eagerness to cure diseases, blindly take some drugs harmful to their bodies, leading to liver cirrhosis, kidney failure and femoral head necrosis. Faced with such a group of patients who cannot be given drugs in vivo, ultraviolet light bath with topical drugs has received good results. For ordinary patients with psoriasis over 12 years old, light therapy is more likely to speed up the healing process. Patients with palmoplantar pustulosis can use topical therapy (256) to reduce the recurrence rate. Phototherapy is even an excellent choice for treating vitiligo. Because oral medications mostly contain photosensitive ingredients, long-term use will increase the risk of cataracts, so patients should be advised to wear glasses with UV protection. The actual fact is that you will find a lot of people who are not able to get a good deal on a lot of things. The internal organs and eyes are far more important than the skin!
