Hello I have gone through your question and understand your concern. Cerazzette is the trade name of desogestrel. This is an oral contraceptive,progresteron-only pill that act by suppression of gonadotropins, inhibition of ovulation,changes in the cervical mucus which reduce the likelihood of implantation and pregnancy. It is true that acne can be due to a fluctuation in hormones caused by periods and pregnancy. Spots form when the sebaceous glands in the skin become clogged with dead skin cells. This can occur when too much sebum is produced due to a change in the levels of hormones; in particular, testosterone, which is an androgen. Cerazzete can help in hormonal imbalance. This pill helps to control the fluctuation in hormones associated with these changes. As endocrinologist i can say that the most effective versions of Contracetive pills for acne treatement contain a hormone blocker that reduce the amount of testosterone in the body thus slowing down the production of oil from the overactive sebum gland. There are several treatment options available for acne, depending on its severity. For women, certain types of combined oral contraceptive pill can be used to help alleviate the condition. -The progesterone-only pill,like cerazzete, is not prescribed to help treat acne. This is because the increase in the progesterone hormone can stimulate the production of sebum, thereby initiating or increasing acne symptoms. At the other side,it is possible that you get acne as a result of taking the mini pill(cerazzete), but if you already have acne then it is unlikely that your GP will suggest this type of contraceptive. My advice for you is to discuss with your Gp about the best treatement for you and to use of a neutral cleansing wash in combination with your pill in order to increase the chances of success. You should also bear in mind that it can take around three to four months before you start to notice visible improvements. Hope this information is helpful for you. If you have other questions,feel free and ask. Regards.
