Oral emergency contraceptive pills usually do not cause acne. The emergency contraceptive pill is a highly effective progestogen, and is mainly used clinically as a remedial oral contraceptive after sex without contraception. The main cause of facial acne is a bacterial infection, mainly caused by Staphylococcus aureus infection. It is advisable to go to the dermatology department for further treatment. It is likely to be a coincidence if the acne is after taking the emergency contraceptive pill. Therefore, it is recommended to go to the dermatologist as soon as possible, and it is also recommended not to use cosmetics during the period of acne, and to keep the skin locally clean. It is also recommended that if you are not planning to get pregnant, it is best to use condoms for contraception, which are safe and have fewer side effects.
