Rosacea is a rash commonly confused with acne. The cause is unknown, but it occurs most frequently in women with a fair complexion who are over 30. Symptoms include a swollen red nose, puffy cheeks, and a persistent blush on other parts of the face. Oral antibiotics such as tetracycline are effective in the treatment, as are topical antibiotics such as metronidazole gel. 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.
