A recent publication by the American Academy of dermatology has advised that one of the biggest acne causing culprits can be milk. Cows are fed hormones to increase milk yields, and ingesting these hormones can inflame acne. This includes all dairy products, such as cheese, yoghurt, and milk chocolate. If you are concerned about blemishes try switching to non-dairy milk (such as soy or almond) and dark chocolate.
Some birth control pills, such as the ‘mini pill,’ do not help regulate hormones and so are not helpful in the treatment and management of acne. Therefore, women who suspect that their hormonal system is making their acne worse should investigate hormone-blocking birth control, ideally containing drospirenone e.g. Yasmin. However, the risks of side effects including blood clots and stroke are increased, especially in smokers, with these types of birth control and so caution should be taken with use. I will sometimes prescribe spironolactone, a diuretic fluid reducing pill that also helps block acne causing hormones.
