Join Allure as we explore the inextricable link between science and beauty — and don't be surprised if you discover your next favorite serum, hair mask, or scalp treatment along the way. Jenny Bailly, executive beauty director, and Dianna Mazzone, senior beauty editor, are asking the tough questions and getting the straight answers from dermatologists, cosmetic chemists, and at least one expert on climate change (we said the questions were tough). So if you’ve always wondered what a wrinkle actually is (and how retinol can make it go away), or why your hair is curly (and which polymers will give it the most spring), come get nerdy with us!
