Psoriasis is related to a variety of factors, including immune system abnormalities, genetic factors, and environmental stimuli. While it cannot be completely cured at present, symptoms can be effectively controlled through proper treatment and daily care. The following are common triggering or aggravating factors:

1. Immune system problems: Disorders of the body's defense mechanisms lead to excessively rapid growth of skin cells, resulting in scaling and erythema.

2. Family history: Some patients have a family history of the disease, but not everyone will inherit it.
3. External environmental stimuli: such as infection, skin damage, dry climate or mental stress may induce or aggravate symptoms.
4. Lifestyle factors: Smoking, drinking alcohol, or certain medications may affect the stability of the condition.
We recommend that you avoid scratching your skin and use gentle moisturizing products; pay attention to regulating your emotions and ensure sufficient rest; if the symptoms are obvious, you should go to the dermatology department of a regular hospital in time, and the doctor will develop a personalized treatment plan based on the specific situation.
