Use of Cosmetics Regular cosmetics can block oil glands and cause new lesions. Cold creams can cause obstruction of oil glands and create new acne. Sex Hormones and Acne Sexual activities have absolutely nothing to do with the development or remission of acne lesions. Some women do notice a flareup of acne symptoms a few days to a week before the onset of their menstrual periods. This can be handled adequately with adjustment of the acne treatments, including increasing the dosage of the medicines you'll be using around that time.
Androgens are male sex hormones.
Acne is considered to be an androgen-dependent condition. Androgen excess, either systemic or local, is associated with more severe forms of the disease. Androgens control sebaceous gland secretion and exacerbate the development of abnormal follicular epithelium. The endocrine glands are any of various glands, such as the thyroid, adrenal, and pituitary, that secrete hormones directly into the blood or lymph. Endocrine disorders producing excess androgens are important etiological factors in the onset of acne.
