Which proteins and molecules are missing in the skin after 30?

The skin needs a set of proteins and molecules in order to maintain its suppleness and get its moisture needs after the age of 30. Among these components, we mention: hyaluronic acid, urea, elastin, and collagen, which are naturally present in the body and decrease with age. But fortunately, these ingredients are available in many skin care products, so make sure they are present in the creams and serums that you use in your daily skin care routine.

Hyaluronic acid to moisturize the skin and fill wrinkles:

Hyaluronic acid molecules are found naturally in many tissues and fluids of the body, but its highest percentage is found in the skin, specifically in its deep layers, and in a smaller amount in its upper layers.

This acid is distinguished for being one of the best anti-wrinkle molecules, as it maintains skin moisture due to its ability to absorb the equivalent of a thousand times its weight in water.

Skin rich in hyaluronic acid maintains its moisture, smoothness, and firmness, as this molecule is able to fill the voids that separate cells, causing the appearance of wrinkles.

Hyaluronic acid forms an ideal shield against wrinkles, as it accelerates the healing of scars and promotes the building of skin tissue. But the natural production of this acid declines after thirty, causing the skin to dry out and lose its compactness. Therefore, it is recommended to compensate for this deficiency by using products rich in this acid or obtaining it through nutritional supplements, and it is also possible to undergo hyaluronic acid injections in the dermatologist’s office in order to fill wrinkles.

Urea to gently exfoliate and moisturize the skin:

Urea is among the molecules produced by the breakdown of proteins in the body. It has many benefits for the skin, and that is why cosmetic laboratories resort to including it in skin care formulations.

The urea in cosmetics is made from ammonia and carbon dioxide. It is a molecule with an exfoliating action that removes dead cells by gently dissolving them and smoothing the surface of the skin.

Urea maintains the moisture content of the skin, as it is one of the ingredients that easily retains water and is suitable for the requirements of dry and sensitive skin.

Elastane to maintain skin suppleness:

Elastin is a protein produced by fibroblast cells, which are found in the deepest layers of the epidermis. Elastin imparts suppleness to the skin, as its molecules can stretch up to 150 times more than their original length before they are broken.

Elastin plays the role of a link between cells and contributes to the formation of vital tissues, and is involved in the functions of the skin, lungs, ligaments, blood vessels, and even tendons.

The level of elastin in the skin decreases with age, causing the skin to lose its elasticity and firmness. It becomes unable to cope with the effect of muscle contractions, the recurrence of which causes wrinkles to appear. Repeated exposure to ultraviolet rays accelerates elastin damage.
The use of elastin-rich care products helps the skin to maintain its suppleness and softness, as tests prove that, starting from the age of thirty, the elastin stock in the skin decreases and it becomes in dire need to compensate for this deficiency.

Collagen for skin firmness and regeneration:

Collagen is a fibrous protein found in significant amounts in the body. It is an essential component of the skin. Collagen is also found in blood vessels, cartilage, teeth, cornea, and the digestive system. Its primary role is to bind cells together thanks to its adhesive properties.
Collagen contributes to maintaining skin moisture and tissue regeneration, which makes it an ideal ally to activate the scar healing mechanism and make the skin more supple and resistant when subjected to stretching.

To compensate for the decrease in the natural production of collagen associated with age, experts recommend turning to care products that compensate for this deficiency and maintain the suppleness and firmness of the skin. Especially since collagen delays the manifestations of aging when used in creams, serums, masks, and even nutritional supplements.
