20 Products You Need to Buy the Day You Turn 30

Why: Before you slap on any old body cream, go for the season's newest iteration: the body serum. The skin on the body changes over time, and a body serum (which is lighter and sinks in deeper) will give you added moisture benefits to keep everything looking tight on the beach. Feel free to layer a heavier lotion over it (like you would for your face) for double the hydrating benefits.

Try: I am a recovering tan-aholic, so L'Occitane Almond Velvet Body Serum ($52) is the perfect remedy for my freckled bod. It has vitamin C and almond native cells to reduce the appearance of those dreaded dark spots. And the floral-almond scent is an easy way to skip perfume on busy mornings.
