Every month right before my period, I get these pimples and it seems I always get them in the same areas. I thought acne was just for teenagers. I am in my forties and I am still breaking out every month before my period. How annoying! —Cecilia V., Miami, FLOily Skin and Acne: The production of sebum by sebaceous glands all over the body is controlled by sex hormones called androgens. These androgens are made by the adrenal gland and the ovaries in women. Certain enzymes in the sexual organs can make these androgens more active, thus increasing the production of sebum. This overstimulation of the oil glands can clog pores, thus producing not only oily skin, but also acne. Thus, if there is persistent acne or worsening of the condition, a hormonal imbalance in the sexual organs could be the cause. During the adolescent years, skin may also appear to produce more oil and acne develops. The developing body also produces more androgens during puberty, thus increasing the production of oil and therefore acne. Breakouts right before menstruation are also signals of hormonal changes in the body that are directly related to our sexual organs.
