Guiding opinions:
You can try the following methods: 1. Rub your hands with salt, you may have a burning sensation for a short time, but it will usually get better soon. After rubbing your hands with salt, it is recommended to rub your hands with vinegar and finally wash your hands with soap. 2. Rub your hands with a little vinegar. The pungent substance in pepper is capsaicin, and vinegar is acidic, which can neutralize the discomfort caused by capsaicin. You can add a little ice water to the basin, but don't put too much ice, or your hands will be uncomfortable if they are too cold. 4. You can wipe the affected area with aloe juice. 5. External coating of toothpaste.
Remember not to wipe your eyes with your hands until the symptoms are relieved. You'd better wear gloves when cutting a lot of peppers in the future.
