I used to go to a private hospital to treat acne on my face. After several treatments, I didn't see any effect at all. I spent more than 2000 yuan, which really hurts. Later, after being introduced by my classmates, I went to the Second Affiliated Hospital of Anyi University, and the doctor gave me laser treatment. Once it was only a few hundred yuan. I did it five times, and it was all right. I dare not go to a private hospital next time. Fortunately, my face was not disfigured, otherwise I would have cried to death.
