U Beauty Resurfacing Compound

• PROS: Helps to smooth and plump skin with antioxidants and exfoliating acids
• CONS: One of the more expensive options on the list

Glycolic acid (one of the main ingredients in this anti-aging serum) has been shown not only to exfoliate but also to stimulate dermal collagen production—two key things for reducing the appearance of fine lines, large pores, and skin discoloration. In addition to glycolic acid, the formula contains hyaluronic acid to plump and smooth skin plus antioxidants (like vitamin C and E) to protect skin from the aging effects of free radical damage. THE REVIEW: "This morning when I woke up I looked in the mirror and felt truly happy with my skin," said one person who tried the product. "This product is amazing—and took the place of three different products in my routine. Seems pricey but it’s worth it if you ask me."
