Mild psoriasis is commonly seen in the punctate form of psoriasis and can be clinically cured, mostly in adolescents. Mild plaque and other types of psoriasis can be treated topically and do not require systemic drug therapy. All types of psoriasis cannot be cured, only controlled. Mild psoriasis with relatively few lesions and PASI score <10 is often treated clinically with topical topical medication, and physical therapy and phototherapy can be added when the treatment effect is poor. Topical treatment can be topical hormone-based and hormone-free drugs, and drugs are selected according to the type of lesions and the site of lesions, for example, mild trunk and extremity punctate psoriasis can be treated topically with carbotriol or moisturizing emollients. For plaque psoriasis with slightly thicker lesions, alternating medium to weak hormonal creams with topical hormone-free carbotriol-based drugs can be used. Local treatment of large plaque psoriasis is not effective, and phototherapy, such as physical narrow-spectrum UV 308 treatment, can be added.
