Why does the skin ages? How to prevent this process?
It is scientifically proven that the skin begins to age at the age of 25. The slowdown in cell production and the decrease in the humidity rate stored by the connective tissue lead to a lower resistance to external aggressions.
Today, when we talk about this phenomenon, we rightly distinguish between “aging due to age” and “attributable to external factors”. The first describes the skin changes related to the normal senescence process, which involves thinning all the layers of the skin, as well as less activity of the skin glands.
At the origin of wrinkles and fine lines there is the lower elasticity of the fibers of the dermis. The speed of this process depends on genetics, although environmental factors play an important role in the aging process, which can accelerate and enhance. In light of these considerations, it is appropriate to treat separately those aspects of aging that depend on external agents. In this case, the determining factor is the amount of UV rays to which you are exposed in the course of your life, to the point that we often speak of “photoaging”. However, there are other factors that accelerate this process, for example a less blood circulation of the skin, following an abuse of nicotine.
The main causes of skin aging are free radicals, which attack the cell walls, changing the genetic heritage of the nuclei and causing a lower quality of the new skin cells.
Based on our current knowledge, vitamin A (retinol) is one of the most effective antioxidants: it stimulates cell renewal, improves the structure of tissues and reduces the depth of wrinkles.
To allow retinol to penetrate the skin, dead cells must be removed. For this purpose, glycolic acid, a natural agent extracted from sugar cane, can be used, which stabilizes the thickness of the horny layer and reduces skin irregularities. Dead corneal cells are gently eliminated, restoring its smoothness and delicate appearance to the skin. Some newly developed products are available on the market that combine vitamin A and glycolic acid.
In addition to these “cosmetic measures”, it is certainly reasonable, in the course of one’s life, to expose oneself to the sun in moderation and reduce the consumption of nicotine (or even give up smoking), because “the skin has memory!”
