The causes of Ageing Skin.

 

What causes the ageing process in skin:

Research shows that there are two distinct types of aging. Aging caused by the genes we inherit is called intrinsic (internal) aging. The other type of aging is known as extrinsic (external) aging and is caused by environmental factors, such as UV Sun exposure and Wind exposure.


~Intrinsic aging, also known as the natural aging process, is a continuous process that normally begins in our mid-20s. Within the skin, collagen production slows, and elastin, the substance that enables skin to snap back into place, has a bit less spring. Dead skin cells do not shed as quickly and turnover of new skin cells may decrease slightly. While these changes usually begin in our 20s, the signs of intrinsic aging are typically not visible for decades.

~A number of extrinsic, or external, factors often act together with the normal aging process to prematurely age our skin. Most premature aging is caused by sun exposure. Other external factors that prematurely age our skin are repetitive facial expressions, gravity, sleeping positions, and smoking.


-Prematurely Aged Skin:

Prematurely aged skin suffers from decreased cellular turnover, photodamage and a loss of collagen and elastin. Approximately every 27 days new skin is regenerated through skin cell turnover. The bottom layer, known as stratum corneum, is where new skin cells originate. As cells are created they crowd and are pushed upward into the next higher layer. As the cells move into the higher layers, they flatten and eventually die. As old, dead skin cells reach the outer surface, they slough off replaced by the upward moving cells below them. This process can take from 40 – 120 days in adult skin. When dead skin cells do not shed rapidly, it results in a dry, dull, wrinkled, uneven complexion.

-Signs of Aging:

-Intrinsic Aging (Internal):

~Dull Complexion.
~Fine Lines and wrinkles.
~Loss of skin firmness.

-Extrinsic Aging (External):

~Rough skin texture.
~Brown spots/pigmentation.
~Excessive Wrinkles/Deep lines.
~Uneven skin Tone.

What you can do to help ease the aging process, both internal and external:

External: Limit sun and wind exposure, and pollutants such as cigarette smoke. Wear a sunscreen of at least 40 SPF if you go out in the sun, rubbing it over the back of your hands as well as your face, chest and ears. Wear proper UV protection sunglasses to avoid squinting. Wash your skin at night with a mild cleanser and lukewarm water. Exfoliate at least once weekly to help cellular turnover. Use an unscented, moisturizing cream or Retinol cream after cleansing at night. 

Internal: Take a daily supplement of CoQ10, Alpha-lipoic acid and Omega fatty acid from a reputable company *(I recommend the AOR company for all supplements.) Be sure to drink plenty of fresh water, green tea and Pomegranate Juice  (because it is loaded with powerful antioxidants called polyphenols that help protect the skin from the inside). Eat plenty of colorful fruits, vegetables, fish, whole grains, Yogurt, Olive oil and any healthy (Omega) fats. *Limit sugar intake, sugar substitutes as well as any fat substitutes or trans fats (Margerine), these items cause oxidation and harm the skin internally.
