It takes a week to scab. If you don't go to scar for a week, you can wash your face to help go to scar. After removing the scab, your skin may turn red, which is normal and needs to be restored for one to two weeks. Main items after washing your face: it is ok to wash your face, but be careful not to touch the scab. If you get wet, you will be more susceptible to infection. Also, when the scab is wet, it will become soft and easy to fall off, but the skin inside is not good yet, so it should be carefully wiped with a towel. Be sure to wait until the scab falls off on its own. It may itch during wound healing, but don't touch it with your hands. This usually scabs after a click (that's what I did), and then it falls off in a week or so. Facial cleanser can be used after dripping, and it took a few days to start using it. Because it is new skin, it is still on my face, so I have been very careful. I should eat more foods containing VC and VE, because VC can prevent melanin deposition, VE can promote cell division, and it also has a cosmetic effect, so that wounds can heal easily. Don't eat spicy food, seafood and other hair products, and don't eat melanin (such as soy sauce, but a small amount is ok, just like dropping a few drops when cooking). Vinegar will leave scars, so it is best not to eat more (the normal amount should be metabolized). Grapefruit is very good. Besides containing VC, there are many benefits. It is a healthy fruit. Dried fruits should be fine, but if you want a moderate amount, such as walnuts, you can eat two or three a day. Eating too much can't be absorbed, but it's wasted. Fruit, kiwi fruit is very good, rich in VC, lemon is also ok, but you can't eat it directly, and your esophagus can't stand it. It is recommended to soak in warm honey, which has a cosmetic effect. This drink is healthy and delicious. If you drink it regularly, it will be good for your health. This way, there will be no pits, and you should pay attention to sun protection or you may grow back. Of course, don't use sunscreen if you can. It contains chemicals and is not good for new skin. You can use an umbrella or something. Actually, you don't have to be so nervous. It's nothing! I often go to some websites to learn this knowledge. Search for girls.
