Useful! Amway! Because of endocrine disorders, acne often grows. After drinking Xiao Yuan for a month, I really don't feel so often. It used to be one for every three days, but now it rarely grows. Of course, sleep is also very important. Internal adjustment+external supplement is really possible. Friends who are troubled by acne like me can try! ! If you have acne, you must pay attention to drink more water and rest more ~
