What is photoaging?
Photoaging is the premature aging of the skin caused by prolonged exposure to solar radiation.
Causes of photoaging
We know that aging is natural. So far we cannot prevent the skin from aging, due to the decrease in the organic production of collagen, elastin and other elements such as hyaluronic acid.
When this occurs, the skin loses firmness, furrows form and wrinkles and sagging appear. This aging is called intrinsic aging.
In addition, there are external agents that can accelerate this process. Pollution, poor diet, sedentary lifestyle and sun exposure are some of these agents. This aging is known as extrinsic aging, which is synonymous with premature aging, and its effects are much more rapid than those of intrinsic aging.
According to some studies, 90% of the symptoms of premature skin aging are caused by exposure to solar radiation.
Effects of photoaging
What exposure to ultraviolet radiation actually does to our skin is that it loses its natural capabilities.
Radiation directly damages cellular DNA by activating oxidative stress and forming free radicals.
Oxidative stress causes cells to stop producing the elements that help them maintain tension, they weaken, lose their ability to retain water, blemishes appear and the appearance of the skin changes.
The parts of the body most affected by photoaging are those that are normally most exposed to the sun, such as the neck, face, décolleté, arms and hands.
How to prevent photoaging
The main tool to prevent photoaging is skin care by applying sunscreen every day of the year, not only in summer. Obviously, sun exposure should also be limited.
In addition to protecting, we must try to moisturize the skin to prevent dryness. It is therefore important to use moisturizing products, or products containing active ingredients such as hyaluronic acid, which enhances the skin’s ability to retain water.
On the other hand, it is important to have an additive that helps to combat oxidative stress. In this way, skin structures are protected and free radicals are combated. To do this, we will look for products with antioxidants.
