Treatment misconceptions: Some patients have not been to a formal hospital, they have chosen to treat themselves with some drugs, and even use hormonal drugs to treat acne. Although there will be some effect for a short period of time, long-term use may get hormone-dependent dermatitis, thus aggravating the condition and poor treatment response.
