Here is the Skin Tip of the Day from Eucerin Skin Care products (*hint* pay attention to these because you may need this info later for the giveaway)!
1) First you should know what causes aging. Skin is composed of two main layers, the epidermis and the dermis, with an insulating layer of fat below, called the subcutis. The dermis provides a network of collagen and other connective tissue elements that act like a scaffold that helps to maintain firm, flexible skin. As you age, the collagen network is diminished and your dermis holds less water.
P.S. Don't forget to take the Skin First Pledge! Help yourself while helping others as well!
