Collagen is a protein frequently used in cosmetics to combat the effects of skin aging. However, do you have in-depth knowledge of this substance that is naturally found in our body? We're going to take a closer look at five benefits of collagen.
The dry weight of skin is made up of up to 80% collagen, which, along with another protein called elastin, plays a crucial role in the firmness and elasticity of our skin.
Our collagen levels are higher when we are young, which is why children have such smooth skin. Collagen production naturally slows as we age. From the age of 20, collagen levels decrease by around 1% per year. From that point on, our bodies are simply no longer able to replace the collagen we lose as quickly as it breaks down. Collagen fibers also become thinner and more fragile.
This is why, to compensate for this loss, many creams and serums contain collagen. They stimulate its natural production in the different layers of the epidermis.
The benefits of collagen:
Collagen is a regenerating element for the skin, because it helps to synthesize and regenerate skin cells. It is particularly recommended in healing treatments which stimulate cell renewal and increase their natural production. In addition, it promotes the regeneration of skin tissues.
Collagen has anti-aging properties because it acts on the elasticity and quality of the skin. In fact, it makes the skin more supple and resistant to stretching, which helps maintain a smoother appearance for a longer period of time. However, natural collagen production declines with age, but certain treatments can help compensate for this loss. Thanks to these treatments, it is possible to delay the appearance of wrinkles and maintain skin quality for longer.
Its gelatinous texture has a film-forming effect which helps preserve a good level of hydration in the skin. Although it does not directly hydrate, collagen plays an essential role in combating skin dehydration. In addition, by acting in synergy with hyaluronic acid in the deeper layers of the dermis, it stimulates its production, which allows hyaluronic acid to capture and retain water to maintain the hydration level of skin tissues. .
