The skin (from Latin pellis) or cutis (from Latin cutis), also called the integumentary system, is the outer layer of vertebrates and one of the most important organs. In humans, it is the largest organ in the body and the layer that protects it.
The people are exposed to a range of external factors, which can alter their genomefrom birth to death. In the case of our skin, these factors act on this, possibly accelerating or simply causing skin aging.
Solar radiation
It is confirmed that the 80% of skin aging is due to sun exposure. People who do not use daily sun protection live 24% longer than those who do. They affect both visible light and UVA rays, which also penetrate the window glass. Infrared radiation and visible light, especially the color blue, have also been shown to have an effect on aging, destroying the skin matrix and forming free radicals.
Pollution
It is a factor that enhances the effect of UVA radiation and we can speak of ‘photocontamination’. According to experts, that will be the case more skin aging, more spots and greater wrinkle formationmore exposure to small particles, higher levels of nitrogen dioxide and higher levels of ozone
Smoking
Is in favor of the development of wrinkles and damages skin clarity and tone. It impairs the formation of fibroblasts and leads to aging. It causes damage from oxidative stress and inhibits the body’s antioxidant defenses, which may be involved in the aging process, experts say.
Power supply
It is responsible for 30% of wrinkles. A diet rich in antioxidants, vegetables, legumes and olive oilIn addition to avoiding alcohol as much as possible, they can slow down skin aging. A diet high in meat, dairy products and butter can be harmful. It has also been seen that consuming a lot of sugar can cause more wrinkles.
Tension
Chronic stress promotes skin aging, according to doctors, although the mechanism underlying this link is still being studied. Some medical data indicates that the Stress causes a decrease in the permeability of the epidermis and impairment of barrier function and its recovery.
Dream
Sleeping less than five hours per night is linked to more signs of aging and with a reduction in the barrier function of the epidermis.
Dangerous cosmetics
The use of certain cosmetics can be positive in combating skin aging because they can serve as a barrier against certain external aggressions, but there are also many products that contain toxic elements. That’s why we have to choose certified organic cosmetics.
Knowing these external risk factors for each individual can help dermatologists identify a risk factor preventive treatment for aging skin. Someone who lives in the south of the peninsula or in the Canary Islands, or who smokes and lives in the countryside, or someone who has a lot of stress, is not the same. But everywhere and in situations you need to take care of yourself and ask professionals for advice for healthy skin and a healthy life.
