The Importance of Collagen and Elastin for Skin Health

Collagen and elastin are well-known terms in the context of skin health. They are the main reasons why our skin is firm, elastic, and looks good. Despite their importance, there is often misinformation about these valuable proteins. Today, we uncover the truth about collagen and elastin and provide guidance on how to enhance their levels in the skin.

What Are Collagen and Elastin?

Collagen and elastin are proteins found in the skin and various other organs that provide essential structural support and elasticity. In the skin, collagen is primarily located in the dermis (the second skin layer), where it forms a dense network of fibers. Collagen fibers give the skin its strength and structural integrity, which allows it to resist stretching and sagging. It also regulates wound healing by helping the skin regenerate and repair itself. Interestingly, collagen is also found in bones, tendons, ligaments, and cartilage, where it provides similar structural support.

On the other hand, elastin is located alongside collagen in the dermis and other connective tissues. Elastin fibers are highly elastic and flexible, with a structure similar to rubber. This elasticity is essential for tissues that need to expand and contract, such as the skin, lungs, and blood vessels. In the skin, elastin fibers help the skin return to its original shape after stretching, which contribute to its overall elasticity and smooth appearance.

How Do Elastin and Collagen Decrease With Age?

As we age, the body’s ability to synthesize these necessary proteins decreases. Fibroblasts, the cells responsible for producing collagen and elastin, become less active over time. Apart from that, existing collagen and elastin fibers degrade over time, which makes them more vulnerable to damage.

External factors, such as UV exposure, exacerbate this process. UV radiation triggers the production of enzymes that degrade elastin and collagen. As their fibers diminish, the skin gradually loses its elasticity and firmness. This results in the formation of fine lines, wrinkles, and sagging skin. 

How to Increase Collagen and Elastin?

To slow the skin’s aging process and maintain healthy levels of these proteins, it is important to protect the skin from UV damage, eat healthy food, and use skincare products that promote collagen production. Let’s explore what else you may do to boost elastin and collagen levels:

Stop Smoking

Cigarette smoke contains a huge number of chemicals that impair collagen and elastin synthesis. For example, nicotine constricts blood vessels and reduces oxygen and nutrient delivery to the skin. Carbon monoxide binds to hemoglobin and decreases its ability to transport oxygen molecules. These effects decrease fibroblast activity and collagen production, which result in lower levels of these proteins in the skin.

Quitting smoking is known to boost elastin and collagen levels by reducing toxic chemical intake and oxidative stress.

Protect Your Skin From UV Rays

UV radiation stimulates the production of enzymes called matrix metalloproteinases (MMPs), which degrade collagen and elastin fibers in the skin. Over time, this leads to a reduction in their levels, resulting in sagging skin and wrinkles. To protect elastin and collagen fibers from breakdown, avoid excessive UV exposure, and use sunscreen regularly. 

Use Appropriate Skincare Products

Several ingredients have been shown to improve collagen and elastin levels in the skin. The most powerful boosters include:

  • Retinoids, such as retinol and tretinoin, are vitamin A derivatives that stimulate collagen production and promote skin cell turnover. Regular retinol use has been linked to improved skin texture and firmness. 
  • Vitamin C is a potent antioxidant that helps protect the skin from oxidative stress, which degrades collagen and elastin fibers. It is also involved in collagen synthesis. 
  • Niacinamide (vitamin B3) has been found to boost collagen production and improve skin elasticity.
  • Hyaluronic acid is a hydrating ingredient that plumps the skin and reduces the appearance of wrinkles. It indirectly increases collagen and elastin levels by maintaining skin hydration.

In the appropriate formulations, these ingredients can promote a healthier and more youthful skin appearance.

Pay Attention to a Balanced Diet

Apart from other health benefits, a balanced diet is essential for increasing the skin’s collagen and elastin levels. Foods rich in vitamins, minerals, and polyphenols support collagen synthesis and protect it from degradation. The most important nutrients for boosting elastin and collagen levels include:

  • Vitamin C – necessary component for collagen production, is found in citrus fruits, strawberries, and bell peppers;
  • Vitamin E – found in nuts, eggs, seeds, and leafy greens, protects collagen and elastic fibers against oxidative damage;
  • Zinc – occurring in seafood, meat, and legumes, is also involved in collagen synthesis;
  • Omega-3 fatty acids – occurring in fatty fish and flax seeds, help maintain skin elasticity;
  • Copper – nuts, seeds, and whole grains are excellent copper representatives;
  • Certain antioxidants, like beta-carotene, found in carrots and sweet potatoes, and lycopene, in tomatoes.

Consider Cosmetic Treatments

Anti-aging treatments improve collagen and elastin levels by stimulating their production and protecting them from degradation. These treatments often work by triggering the skin’s natural healing processes, which include the production of new elastin and collagen fibers.

Some treatments, such as laser therapy and radiofrequency, use heat to stimulate collagen production. Other cosmetic procedures, like microneedling, create controlled micro-injuries to the skin to promote collagen remodeling. 

By enhancing collagen and elastin levels, cosmetic treatments improve skin firmness, elasticity, and overall texture. The occasional use of these treatments, along with appropriate skin care and healthy lifestyle habits, can help maintain their optimal levels in the skin over time.


Frequently Asked Questions


What food is highest in collagen?

Bone broth is the best source of collagen. It is rich in collagen derived from animal bones and connective tissues. Other sources include beef, pork, chicken, fish, sardines, shellfish, and eggs. 


What vitamin deficiency causes sagging skin?

A deficiency in vitamin C contributes to sagging skin. Vitamin C is essential for collagen synthesis, and its low levels can weaken collagen fibers and reduce skin elasticity. This deficiency can result in skin that looks loose, sagging, and more prone to wrinkles.
