collagen

no, not the injections. i'm talking about natural collagen... the kind that your body produces!

so, what is collagen?
Collagen is a major structural protein in the skin. It plays a key role in providing the structural scaffolding for cells, tissues, and organs. If it weren't for collagen, the body would literally fall apart. Collagen also gives the skin its strength and durability and is responsible for the smooth, plump appearance of young, healthy skin. Understanding the structure and function of collagen will help you better know how to maintain a healthy, youthful appearance. (source: nuskin.com)

Basically, collagen keeps your skin nice, tight and plump (in a healthy, non-fattening way). Take this example: PORES. Why is it that little kids don't have any visible pores? It's because they have an abundance of healthy collagen (and elastin + other biological and environmental factors). as we age, our collagen production decreases and/or breaks down, causing our skin to look dull, thin, wrinkly, and loose. Sucks to get old, ey?

ways to promote collagen production
There are many ways to promote the synthesis of new, healthy collagen. First, you can provide the skin with a reserve of vitamin C. As a necessary cofactor in collagen synthesis, vitamin C is proven to increase the production of collagen. One study showed that extended exposure of human connective-tissue cells to vitamin C stimulated an eight-fold increase in the synthesis of collagen (Murad et al., 1981).

Another way to promote the synthesis of collagen is to use chemical exfoliants, such as alphahydroxy and polyhydroxy acids, which break down the bonds between cells of the stratum corneum and slough away dead skin. Consistent exfoliation stimulates cell renewal. Chemical exfoliation has also been shown to increase dermal thickness. Scientists attribute this dermal thickening to the synthesis of glycosaminoglycans and collagen within the dermis.

A third way to promote collagen synthesis is to supplement with collagen stimulating peptides. Fibroblasts are naturally stimulated to begin the synthesis of collagen when specific combinations of peptide signal molecules (fibroblast growth factors) bind to receptor sites on the fibroblast membrane. These signal molecules can be supplemented with topically and help boost collagen production. Some skin care companies are including these peptide fragments in their treatment products.

Because collagen gives the skin its strength, durability, and smooth, plump appearance, it's important to protect and promote collagen growth. Taking good care of your skin means taking care of your collagen. (source: nuskin.com)
