Wrinkle Prevention with Collagen, Keratin Keratin is an extremely strong protein found in the skin, hair, and nails that helps make skin waterproof, while restricting the ability of chemicals and pathogens to gain access to your body. Along with collagen and elastin, keratin gives skin its strength. It is made by specialized cells in the skin called keratinocytes.
If skin is rubbed or pressure is applied, keratin is produced in larger quantities, and calluses develop as, for example, when the skin of your big toe joint hardens from rubbing against the inside of your shoe. You may not appreciate calluses, but athletes and musicians do because it protects their skin from repetitive rubbing.
Perhaps you’ll appreciate your keratin more, though, when you realize that it helps prevent sagging and wrinkling. Having too many of these dead keratin cells, however, can dull your appearance. Facial scrubs are designed to remove excess keratin cells so the natural glow of your skin can be seen.
Wrinkle Prevention Collagen
Collagen, which is found throughout the body, is a protein that holds the dermis together and supports the epidermis. It gives skin its strength and durability, and is a vital part of the internal scaffolding responsible for smooth, tight, beautiful skin. Understanding the structure and function of collagen can help you maintain a healthy, youthful appearance.
Collagen is a protein with a triple helix structure that provides a strong framework to support cells. Its tensile strength (the ability to resist force without tearing apart) is greater than that of steel, which explains why your skin is so strong. About one-third of the protein in your body is collagen. It supports your tissues and organs and connects them to your bones. Even your bones are made from collagen, along with minerals like calcium and phosphorus.
Perhaps collagen’s most important role is providing the structural scaffolding that surrounds cells and supports cell shape and differentiation, just as steel rods reinforce a concrete block. The mesh-like collagen network binds cells together and provides a supportive framework where cells can develop and function. This framework aids in the healing of tissues and bones, just as scaffolding helps construction workers build walls.
Collagen makes up 75 percent of our skin. Healthy collagen levels give skin a smooth, plump, young, healthy appearance. A breakdown in collagen or a decline in collagen production, however, leads to unwanted wrinkles and the appearance of aged skin. As a result, beauty seekers try to find ways to boost collagen levels and repair collagen damage. Adding nutrients such as vitamin C, which is known to support collagen production, to skin creams is one way to increase collagen synthesis in the skin. Some will go as far as to inject collagen directly into the skin and lips to achieve the desired smooth, plump appearance.
