Reduced Elastin Production 

Elastin is a protein found in connective tissue. It is the key substance that causes the skin to tighten back to its original shape after stretching or contracting. In other words, it provides flexibility. As we age, the cells shut down elastin production. You will notice with older skin that it has lost its elasticity. If you put pressure on it, it takes a few seconds to return to its original shape. This demonstrates loss of elastin. Elastin cannot be absorbed into the skin, but use of other ingredients in skin creams, such as those found in Corium 21 can moisturize the skin and provide a more elastic quality and appearance.
