Promoting the synthesis of collagen is another way to encourage healthy, plump, smooth skin. This means providing the skin with vitamin C, an important cofactor required to convert collagen subunits into active collagen proteins. Because vitamin C is water-soluble, it cannot build up in the body and form reserves, so consuming vitamin C–rich foods frequently is important to ensure that your skin can make collagen.
Wrinkle Preventer #3 Elastin
Elastin is a coil-like protein that helps the skin resume its shape when poked or pinched. A decrease in elastin can cause the skin to lose its firmness. With age, the body produces more of a hormone called DHT, which inhibits elastin production. Thus, as we age, elastin production decreases, and the resilience of existing elastin fibers diminishes. This results in areas of decreased firmness, especially along the jawline, along the neck, and around the eyes. In addition, repeated mechanical stress to elastin (from frowning, for instance) can permanently stretch out these fibers and lead to sagging and wrinkles.
Maintaining Your Skin
Ever wonder how clean your skin really is? Dead skin cells are continually sloughing off the epidermis. Sweat and gland secretions are excreted continually in your skin, and dust, dirt, and other environmental pollutants land on your skin all day long. Together, these create a filthy layer on the skin’s surface. Minimizing this layer of grime will help your skin’s complexion shine, allow your skin’s functions to work properly, and reduce the chance of infection, inflammation, or acne
A layer of dirt on the skin blocks some of the skin’s functions, including the production of antibacterial compounds. Unclean skin is a good environment for the growth of bacteria, which can lead to infection (not to mention an unpleasant odor). Proper hygiene practices can prevent dirt from accumulating on the skin, and wearing season-appropriate clothing can help sweat on the skin properly evaporate. Nutrition can also offer the skin healthy oils (e.g., monounsaturated fats, omega-6 fatty acids) to promote a balanced, healthy moisture level.
Understanding Acne
When pimples become chronic, the condition is called acne. Acne can result from an overgrowth of certain microorganisms or from too much oil on the skin. Other factors can promote clogging of pores as well, such as an accumulation of dead skin cells in hair follicle shafts.
Propionibacterium acnes is a relatively slow-growing bacteria that is linked to acne. This bacteria lives on sebum, which is the fatty acids in the sebaceous glands at the base of hair follicles. People with acne have more P. acnes than do people without this skin condition.
This bacteria can generate enzymes that degrade the skin, as well as proteins that elicit an immune response from the body. In other words, the presence of these bacteria on the skin attracts white blood cells to the follicle. White blood cells consequently produce an enzyme that damages the wall of the follicle, allowing the follicle’s contents to enter the dermis. The result is the red bump that typically surrounds a pimple.
Understanding Oily Problems
The glands in the skin provide moisture that is necessary for avoiding dryness and psoriasis, but too much moisture can result in oily skin, which is susceptible to clogged pores. Oily skin can appear greasy or rough in texture and have large, visible pores.
