But pay attention to the following points:
1. The cleaning time should not exceed 5 minutes, so as not to affect the efficacy.
2. If the skin is damaged, it is not recommended to use wormwood kneepads, because wormwood kneepads may irritate the damaged skin and cause unnecessary pain.
The above suggestions are for reference only. If you encounter any problems during use, it is recommended to consult a doctor or a professional.
