We all want our skin to stay firm and plump and it's mainly thanks to collagen and elastin, two proteins naturally present in our body. However, as we age, the production of these proteins tends to decrease. We explain to you!
Collagen is a "structural" protein that is naturally present in our body in the form of fibers in the deep layers of our skin. It plays a supporting role and resists the stretching of the skin. It is thanks to him that the water is better absorbed, the skin is more toned and rebounds.
Elastin is another fibrous protein that is responsible for providing flexibility to the skin but also to the arteries and lungs. Like a rubber band, elastin allows the skin to stretch and return to its original size. Elle is therefore essential for plump skin.
Hyaluronic acid is also a natural constituent of the dermis. It acts like a sponge by capturing and retaining water and supports collagen and elastin. By ensuring the function of hydration, the skin is denser and firmer.
From the age of 30, the content of hyaluronic acid and collagen gradually decreases. Thus, the skin loses support, which breaks or weakens the elastin. As a result, the skin becomes less firm and plump over time. This can be explained by several factors: a vitamin C deficiency, a decrease in estrogen in women (accelerated by menopause), poor diet, tobacco, stress, the sun (UV rays).
