Pay more attention to the intake of vitamin C in your diet at ordinary times, which can promote the wound to heal faster. I used to have an oral ulcer, so I put a piece of VC on the wound and it will be much better the next day. It is recommended not to eat too much a day, otherwise the body will be seriously short of VC and get sepsis after the wound heals. If you are a vegetarian, you can choose fruits and vegetables with more vitamins, and it is best to eat more protein and collagen, because the main component of skin is protein, like pigskin upstairs. You can't just eat vegetarian food if you want your skin to heal. You need balanced nutrition to get better soon.

Skin injury should eat less irritating food, seafood, etc.
