Collagen and Elastin: What are they & How are they interrelated

Collagen and Elastin are proteins that are generated in the matrix of the cells that make up the dermis. Our body naturally produces these two components, however, over time, the amount we produce begins to decrease significantly and therefore, we begin to notice small lines of expression and a lack of firmness on our face.

What is the specific function of Elastin and how does it differ from that of Collagen?

What is Elastin?

Elastin is a protein that makes up connective tissues, bone system and cartilage. It forms fibres that build a kind of network that allows the skin to stretch and return to its place with each movement. In other words, it acts as a kind of elastic band for the skin, especially in bodily processes such as weight loss and gain.

This protein is responsible for preserving the hydration of the dermis, protecting the collagen fibres and keeping them in place, to preserve the elasticity of the skin and its firm appearance. It is composed of amino acids such as valine, proline, glycine, lysine and alanine; and contains minerals such as magnesium.

However, when the elastin fibres are stretched to the maximum they break, and at this moment the tissue suffers an injury that gives rise to the formation of stretch marks. The lack of elasticity of the skin occurs at critical moments such as puberty, pregnancy, or constant weight gain and loss.

Also, the passage of time,  sun exposure, poor diet and poor hydration can prematurely age the skin, and the body decreases the production of elastin.

Just as we can use special skincare products to avoid cumulative damage to elastin, we can also extract it from a diet that includes soy derivatives, green leafy vegetables (chard, spinach, lettuce, among others), foods that have a sulphur (asparagus, meat, eggs, among others). As well as foods rich in Zinc  (dark chocolate, oysters, crabs, among others), and finally foods that contain Vitamin A (melon, mango, carrots, among others).

Functions and benefits of Elastin

Among the numerous functions, properties and benefits of this protein for health, especially for the skin, we can find:

• Provide elasticity.
• Keep skin hydrated
• Prevent breakage of connective tissue fibres
• Prevent the appearance of stretch marks
• prevent sagging
• Helps fight against the symptoms of ageing (avoiding wrinkles)
• Improve the synthesis of natural collagen
• Give resistance to cartilage, bones and muscles.
• Extension and relaxation function.

It contributes to the union of cells and the formation of biological tissue, which is why our lungs, cartilage or blood vessels need to function properly.

Differences between collagen and elastin

Collagen and elastin are two very important proteins for the functioning of the body that, although closely related, do not have the same functions.

Collagen is an essential protein that is present throughout our body. We find it in the bones, tendons, muscles and skin; and its main function is to provide strength, structure and support, that is, it maintains the firmness of the skin.

For its part, elastin also has structural functions, but, unlike collagen, it ensures elasticity rather than resistance. In addition, it is part of the connective tissue of the skin that forms fibres (similar to an elastic net), keeps the skin looking good, preserves the hydration of the dermis and protects the collagen fibres.

The involvement of both proteins in the appearance of the skin explains why many facial treatments have them among their components. However, these proteins are not only important for beauty but also for the proper functioning of the body.

How to maintain Collagen and Elastin?

The objective is to show off the healthy skin and prevent the appearance (or multiplication) of the signs of ageing, so we can help our body to continue producing these substances in the following way:

• Choose foods that help you with the production of collagen and elastin- A diet rich in minerals, vitamins, amino acids and antioxidants is essential for protein formation.
• Maintain good hydration- Water is essential as it is involved in all biological reactions, including the synthesis of collagen and elastin
• Use products that stimulate the natural production of collagen and elastin. Today you can find skincare products on the market that contain active ingredients to reactivate the production of collagen and elastin  in your body
• Use Sunscreen daily- The formation of free radicals is the worst enemy of collagen and elastin fibres, so we recommend using a photo protector that prevents sun damage and in turn contains antioxidants to prevent the formation of free radicals.
