Skin aging occurs due to a number of factors, both internal and external. To prevent skin aging, we must first understand its origin.
How does skin aging manifest itself?
The skin splits into three layers, which are the epidermal, dermal and subdermal layer. The skin aging manifests itself in each of the skin layers, with different features:
- Cell renewal on epidermal layers becomes slower and lipid production declines, causing roughness and dryness of the skin surface. Therefore, this layer of the skin becomes more sensitive to UV light as it ages and causes a decrease in their immune system.
- Starting a reduction of collagen and elastin in the dermal layers, which act as a shield on the surface of the skin, resulting in the appearance of wrinkles and loss of normal brightness of the skin.
- There is a reduction in the number of cells that store lipids on the subdermal layers, which represent the largest source of energy for the body. This leads to the loss of volume, forming deep wrinkles, stretched skin and a deterioration in the immune system, slowing the healing of wounds.
Internal and external factors that cause skin aging
We may retard the aging process of the skin, however, some of the causes of aging are inevitable. Age determines changes in the skin and the efficiency of cellular functions, which declined with the passage of years.
The natural aging process called intrinsic aging and the aging process caused by external factors is called extrinsic aging. Both show up visibly with the same results, yet the extrinsic aging is the one that we can fight against.
What are the internal factors that cause skin aging?
Without an efficient blood supply to the skin, to provide oxygen and nutrients, the natural glow of the skin disappears and changes to a duller skin tone.
Genetics plays an important role in the skin aging. Besides, race and skin type are a key factor in accelerating the appearance of wrinkles.
What external factors cause skin aging?
The external factors affecting skin aging, are due to the release of molecules called free radicals, or reactive oxygen species in the body. Consequently, lifestyle accelerates and triggers the process of aging by several external factors.
Some of these factors are:
- Sun exposure is the number one reason the skin ages. Exposure to UV rays is the main external factor responsible for skin aging. Hence, is is also responsible for the uneven pigmentation.
- Repeated facial expressions lead to fine lines and wrinkles. Sleeping position also has a similar effect since the skin is pressed up against the pillow for many hours, every night.Allow the nude skin to pollution, can cause the release of harmful free radicals to the skin. As a result, it worsens the effects of sun exposure.
- Smoking speeds up the aging process significantly because cigarettes contain nicotine chemicals. Therefore, are responsible for the increase of free radicals in the skin, intensifying the effects of sun exposure.
- Repeated facial movements for smoking can cause mouth and lip wrinkles.
- Alcohol consumption deteriorates the skin-protecting, antioxidant Vitamin A supply in the skin, which can also lead to liver damage which results in a pale and dull complexion.
- Poor diets lacking in protective, antioxidant and vitamins, lead to unhealthy looking skin. Antioxidants neutralize free radicals that damage the skin and accelerate aging.
- A diet with lots of fruits and vegetables, rich in antioxidants, can become a fundamental tool in preventing the aging process.
- A poorly care system makes our skin ages faster. We can maintain a healthy skin, using appropriate products for our skin type, together with an effective sunscreen when exposed to sunlight.
