THEY SAY: The formula contains vitamin E, chamomile and sunscreens to effectively protect your skin against the sun’s harmful UV Rays as well as premature aging.

WE SAY: Keep reading for reviews from Style staffers!

Pros: It made my face shiny, but not in a greasy way. It was more like I had just gotten a facial. It was the first time a product gave me that JLo glow!Cons: I wish the SPF was higher. —Danielle D., Editorial

Pros: It protected my face from the sun during an all-day hike. I also like that it’s designed specifically for the face, so you can skip the pore-clogging sunscreen and still be protected.Cons: When you first apply it, the serum can feel a little greasy on the face. But if you give it a minute to sink in, it completely absorbs.—Kathryn C., Editorial

Pros: This serum gave my skin a moisturizing healthy glow when I applied it before my makeup. I love that it provides sun protection without the usually shiny effect most SPFs leave. And, because the bottle is smaller, it was so easy to carry it around with me even in a small clutch.Cons: While perfect when topped off with makeup, the serum leaves a greasy look when worn alone.—Jessie C., Editorial

Bottom Line: This face serum magically gives you a glow and doubles as an SPF. Sounds like a winner to us!
