Period skin is skin that breaks out in blemishes right around that time of the month. It's common for acne breakouts to occur during this time due to hormonal fluctuations that are linked to the menstrual cycle. Understanding this can help you be patient with yourself and your skin. Paying extra attention to eating healthily during this time and avoiding high glycemic foods can help as a preventative move in the days leading up to your period. Additionally, getting in enough sleep and cleansing your face in the morning and the evening are two other steps you can take.
