Hormones Glossary

As women, we hear talk (and blame) of our hormones all the time. But what do they really mean for our bodies and our skin? 

As the body’s chemical messengers, hormones control everything from your metabolism and development to reproduction and your response to stress. Balanced hormones are essential to maintaining the healthy ecosystem you need to thrive. This guide will help you understand each of the hormones — what they do and the questions to ask about them.
