Collagen is an ingredient in many anti-aging creams and lotions. Often referred to as your "fountain of youth," the reservoir of collagen in your skin gets more shallow over time and repeated exposure to the elements. Before you invest in skincare products such as collagen creams, be aware that the type of collagen they contain won't put collagen back into your skin–but they can improve your skin's texture and appearance.
Collagen and Your Skin
Collagen is a protein that makes up 30 percent of your body mass, says skincare expert Paula Begoun. Collagen is found in not only in the skin, but in your tendons, blood vessels, bones and organs. Collagen is the most common protein found in your skin, says the Cleveland Clinic, comprising 75 percent of your skin's dry weight. Collagen collaborates with elastin, another protein, to give your skin structure and elasticity.
Collagen Depletion
The inevitable process of growing older causes collagen depletion, called intrinsic aging. This starts in your mid-20s. However, other factors can cause collagen damage, most notably repeated sun exposure, says the American Academy of Dermatology. Reduced levels of collagen are associated with the fine lines on your face and other signs of aging.
Collagen in Skincare
The type of collagen added to anti-aging creams comes from animal sources, according to Cosmetics Cop; however, "pseudo-collagens" derived from plants may also be used in personal care products. Collagen is an efficient water-binding ingredient, regardless of its form.
Effect On Skin
When used as an ingredient in anti-aging creams and other skincare products, collagen won't cause your skin produce or build its own collagen. Begoun points to alpha hydroxy acids or beta hydroxy acids as good exfoliating ingredients to look for on your product's label if you want your skincare product to encourage new collagen growth.
How Collagen Creams Benefit
Collagen is a sufficient "skin-identical ingredient" you might want in your anti-wrinkle moisturizer, Begoun says. Collagen creams provide a protective barrier for your skin, allowing it to retain moisture while it self-repairs. In the process of mimicking the skin's structure, collagen creams give your face a smoother, dewier appearance.
