Winter is better, and the probability of infection is less when the temperature is low. It is best not to wash with water within one week after ordering. When you feel uncomfortable, you can gently wipe it with a clean sterile cotton swab. Don't knock on the door with your hands and feet. I haven't eaten hair since noon. Hair is a food that will scar and entangle. For example, tofu, beef, spinach, mutton, coriander, ginger, and all spicy and heavy foods should be eaten as little as possible or not. At the same time, avoid soy sauce, tea, coffee and all foods and drinks with strong melanin. Normal people's skin growth cycle is generally 28 days, and the metabolism is at most one month slow. During this period, the new skin can be restored to normal as long as it is taboo, sunscreen and laser. I hope my personal experience is useful to you O(∩_∩)O
