1. Genetic factors: Goosebumps are mostly autosomal dominant inheritance, and the incidence rate is higher if there is a family history.

2. Endocrine disorders: hypothyroidism, Cushing's syndrome, long-term use of glucocorticoid and other reasons may cause skin damage, which may lead to the symptoms of goose bumps.

3. Vitamin deficiency: If nutrients such as vitamin A and vitamin B are lacking, symptoms of goose bumps will also occur.

As for whether the use of Chen Yangzhixing shower gel with body lotion will have an effect, it needs to be judged according to the specific situation. If these products contain ingredients that can improve goose bumps, such as some antioxidants or keratin softeners, they may have certain effects. However, if goose bumps are caused by serious skin diseases or endocrine problems, then these products may not solve the problem. Therefore, it is suggested that you should pay attention to maintaining good living habits and skin care while using these products, and consult a doctor or dermatologist if necessary.
