There are several solutions:
1. Stick it on the affected area with wide adhesive tape (it is recommended to use wide transparent adhesive tape), then take it off, take it off and replace it with a new one, continue to stick it and then take it off. Just remove three pieces of tape, which will stick the thorn. There is also a premise that you don't sweat. If you sweat, wait until the sweat is dry before sticking it with tape, otherwise the effect will be bad.
2. Apply baking soda or edible alkaline noodles with some water to the affected area, or apply toothpaste or essential balm to the affected area. There is also an indigenous method, which uses the body fluid of pepper to smear the affected area, but you can't touch the thorn again.
3. If it is particularly serious, it is recommended to seek medical advice.
