The Science Of Skin Aging

There are basically two types of aging – intrinsic and extrinsic aging. The first is genetically driven and cellular programmed thus inevitable. The second – extrinsic or skin aging – is caused by the exposure to various environmental stressors which can be mitigated through proactive and preventive measures such as adopting a healthy lifestyle by eating a well-balanced diet and not smoking.

After the age of 30, the population of melanocytes decreases by 6-8% every decade, leading to hypopigmentation and hyperpigmentation of the skin. The Langerhans cells – found on the surface of the skin and prevent harmful microbes from entering the body – decrease in their quantity and density.

This leads to a lowering of the immune surveillance and contributes to the increased occurrence of premalignant and malignant lesions. Aging also causes disruption in the reproduction and differentiation of keratinocytes, resulting in cell loss and replacement imbalance at the top layer of the epidermis.

Look Out For The Signs

A fundamental characteristic of skin aging is the loss of the body’s adaptability and ability to maintain its internal strength and resilience against environmental stressors.  Most of the skin damage is caused by continuous exposure to UV rays and changes in the skin are typically visible and noticeable through the appearance of fine lines and wrinkles due to the loss of elasticity of the skin.

Dryness and roughness of the skin are commonly associated with aging skin.  There could be due to several factors such as a decrease in moisture content of the stratum corneum, the vertical height of the epidermis, and an increase in the overall surface area of epidermal cells and abnormalities of cholesterol synthesis. This would make the skin look flatter, less flexible and increase its vulnerability to shearing forces due to the reduced shared area between epidermis and dermis.  

The most visible change in aging skin is in the dermis, noticeable by the appearance of fine lines, wrinkles and crow’s feet. UV radiation and the presence of free radicals within the skin cause the enzyme elastase to degrade the elastin fiber network. The gravitational forces pull and stretch the elastin fibers, causing the skin to be the leathery, wrinkled and saggy.

Simple Tips For Skin Youthing

First, wash your face correctly by using a mild but effective cleanser that clears impurities without stripping excessive sebum. Next, ensure that you get at least 7 hours of good quality sleep every night because the lack of sleep increases cortisol, which in turn ups sebum production and leads to oily skin, enlarged pores and acne. Third, hydrate the body properly by drinking adequate clean filtered water, using a good moisturizer and keeping surroundings well-ventilated. Third, maintain a nutritious diet high in electrolytes and minerals to promote homeostasis (balanced internal environment) and improve skin health. In addition, avoid sugar as it forms a free radical called Advanced Glycation End Products (AGEs) in the blood which degrades collagen structure in the skin, causing dullness and wrinkles. Finally, pop a First Light Ceramides Skin Supplement daily – Ceramiracle’s award-winning beauty capsule that hydrates and moisturizes the skin to help maintains its youthfulness.
