NIB: THE HIGHLIGHTER/UNDEREYE TREATMENT COMBO STEPHANIE JUST DISCOVERED

The "A.C.E." in this product's name actually stands for the vitamins you'll find in the formula. Vitamin A is a potent anti-ager, lauded for its abilities to soften fine lines; E is moisturizing; and C is an antioxidant that brightens, tones and firms skin. The 10 percent concentration of the latter in this formula is more than you'd find in plenty of straight skin-care products, making it especially impressive.
