With age, cell renewal decreases, skin loses its elasticity and density and also becomes dehydrated. Consequently, wrinkles are formed, particularly in the face because it is permanently exposed. Wrinkles also form throughout the whole body, although they are less deep.
Aging is caused by both external and internal factors. External causes include environmental factors, for example solar radiation, while internal factors such as genetic heritage also play a role in aging.
Depending on skin tone, for example Asian or Caucasian, the manifestations that aging produces are different : in the former, spots appear before wrinkles, while in the latter, the reverse is true.
Oxidative stress is a very important biological factor. It occurs when an imbalance in the cells exists between free radicals – which produce oxidation or aging cells due to poor regenerative function – and antioxidants that our body needs to fight against the oxidative stress caused by the free radicals.
The first signs of aging begin with expression wrinkles becoming deeper and more clearly defined, followed by crow’s feet, lack of brightness, spots, loss of elasticity and the apearance of flab.
This is because with the passage of time decreased collagen fibers and hyaluronic acid tend to disappear. These pillars maintain the structure of the skin in the dermis-epidermis junction and provide smooth and dense appearance of youthful skin.
