What it is: A powdered vitamin C supplement for your face that helps boosts collagen, fight sun damage and firm skin.

What it does: Vitamin C is an ingredient that's hard to stabilize, which means that most products that tout its benefits lose their potency somewhere between manufacturing and hitting shelves. Topical-C is a powdered Vitamin C, meaning that it only activates when mixed into your existing moisturizer, serum or face oil. Add to your regular routine for a brighter, more even appearance.

How to use: Add two to three shakes of powder to your moisturizer, serum or water, mix in the palm of your hand, and apply to clean, dry skin. It can be used morning or evening.
