In treating psoriasis, injections of biologics can usually improve symptoms relatively quickly. However, the specific type of injection should be determined by a doctor based on an assessment of your condition; self-diagnosis is not recommended.

1. The role of biologics: These drugs reduce inflammation and skin lesions by modulating the immune system, and may show significant effects within weeks for moderate to severe patients.

2. Examples of common types: Currently, there are different types of biologics available, such as drugs targeting specific inflammatory factors. Your doctor will choose the appropriate type based on your physical condition, medical history, and the severity of your condition.
3. Necessary examinations before treatment: Before starting injections, a physical examination and laboratory tests are usually required to rule out risks such as infection and ensure medication safety.
4. Effects and individual differences: Although biological agents take effect relatively quickly, everyone's response is different, and some people may need to combine them with topical medications or phototherapy for comprehensive management.
We recommend that you first visit the dermatology department of a reputable hospital for a comprehensive evaluation. Communicate fully with your doctor about your treatment expectations and physical condition to jointly develop a suitable long-term management plan, and have regular follow-up examinations to monitor the effectiveness and safety of the treatment.
