The Miracle Serum Emily Ratajkowski, Rosie HW, and More All Use Religiously

Retinol products have come a long way since their genesis. Originally used as an acne treatment, scientists quickly realized that this heavy-hitting exfoliator was actually a powerful and untapped anti-ager. A byproduct of vitamin A, retinol works by removing dead skin cells to encourage cell turnover. Thus, pores are unclogged and dull skin is diminished to make way for a new, healthy complexion.

Today's retinol features a more stabilized form of the ingredient that has an advanced shelf life and is even more potent than earlier formulations.
