I'm going to travel soon, how to improve my skin quickly?

First of all, you should make sure that this situation is not a precursor to your physiological period.

If not, then first of all, we should standardize our diet and regulate our sleep.

Food is mainly vegetables and fruits, and meat intake is controlled. That is, breakfast milk/soybean milk+bread/wowotou+cucumber/tomato; Have a little rice for lunch, more vegetables and less meat+1 apple, dinner paste/mung bean porridge+cold salad, avoid spicy food, drink plenty of water, stay in the air-conditioned room as little as possible, take a walk after meals+aerobic exercise, 10 sleep, and get up at 7: 00 in the morning. I think your acne will disappear. There are acne mainly because of endocrine disorders, or maybe you are too excited. It is also important to keep a peaceful mind. I hope you have a wonderful trip!
