Follicle Stimulating Hormone (FSH)

Produced in the pituitary gland, FSH acts as something of a messenger hormone during the menstrual cycle. As the ovulation phase approaches, FSH levels spike and signal to the ovaries that it’s time to produce an egg. Because this hormone is only active for a brief time each month, its direct effect on the skin has not been studied, but its healthy functioning is critical to fertility.
