For women, the cause is often hormonal. As we explained above, hormones influence sebum production and play an important role in the development of acne.
Why do these annoying pimples always appear during that one period of the month? One week after ovulation (which takes place about 14 days before menstruation) many women develop acne. This has to do with the hormonal balance in the body. After reaching a peak (ovulation), the amount of estrogen in the body decreases and the amount of progesterone increases. And yes, progesterone is the hormone that stimulates sebum production and in this way stimulates the formation of pimples.
"Other things or phases can also lead to a change in the hormone balance and associated acne upsets" says Dr. Ostijn. "Think for example of: a pregnancy, stopping the pill, taking a pill with progestogens or switching to an IUD".
In addition to these hormonal influences, there are also lifestyle factors that can play a role: genetic predisposition, wearing a face mask, specific medication, cosmetics, smoking, pollution. Stress often plays a role in people in their thirties.
