As we age, our skin goes through many changes. One of the key factors that contribute to youthful, glowing skin are two powerful proteins: elastin and collagen. These proteins work together to maintain the firmness, elasticity, and smoothness of our skin, helping us hold on to that radiant, youthful appearance.

But as we get older, the production of elastin and collagen naturally slows down, leading to wrinkles, sagging, and loss of skin resilience. Understanding how these proteins work—and how we can support them—can make all the difference in maintaining a vibrant, youthful complexion. In this article, we’ll dive into the roles of elastin and collagen in skin health and explore how you can keep them at their best for glowing, youthful skin.

What is Collagen?

Collagen is the most abundant protein in your skin, making up about 75% of its dry weight. It's like the framework of a building, providing structure, support, and elasticity. Think of it as the glue that holds your skin together, giving it strength and keeping it firm. Collagen is woven throughout the skin in a dense network, creating a foundation that ensures your skin has the right structure and integrity.

The Role of Collagen in Skin Health

Collagen's primary function is to maintain your skin’s structure and elasticity. It helps your skin stay firm, smooth, and plump. Without collagen, your skin would lose its firmness and ability to snap back after being stretched. The fibers of collagen are long and strong, and when they’re intact, they act like a net, preventing your skin from sagging or drooping.

This is why collagen is often referred to as the "scaffolding" of your skin—it’s what gives your skin its youthful, taut appearance.

As we age, collagen plays a crucial role in keeping our skin youthful. When collagen levels are high, our skin looks full, smooth, and vibrant. It helps to minimize the appearance of fine lines and wrinkles by keeping the skin tight and hydrated. The more collagen you have, the less likely it is that your skin will develop those signs of aging.

The Decline of Collagen with Age

Starting as early as your mid-20s, your body begins to produce less collagen each year. On average, you lose about 1% of your collagen every year after the age of 20. This slow decline is not noticeable at first, but over time, the effects begin to show up. By the time you reach your 30s and 40s, the loss of collagen is much more evident.  (1)

Your skin may start to lose its elasticity, becoming thinner and more fragile. You might notice that your face looks a little less plump, and the lines and wrinkles around your eyes, mouth, and forehead become more pronounced.

The decrease in collagen also leads to a loss of skin volume. As collagen breaks down and is not replaced as efficiently, the skin can begin to sag. The cheekbones may lose some of their fullness, the skin may appear less firm around the jawline, and the overall contour of your face might look less youthful. This gradual breakdown of collagen fibers is one of the key factors behind the development of sagging skin and the deepening of wrinkles.

External Factors That Accelerate Collagen Loss

While the decline of collagen is a natural part of aging, several external factors can accelerate this process, leading to earlier signs of aging. For instance, sun exposure is one of the biggest culprits. UV rays from the sun break down collagen and elastin in the skin, speeding up the aging process and leading to premature wrinkles and sagging. (2)

This is why it’s so important to use sunscreen daily, even on cloudy days, to protect your skin from the harmful effects of UV rays.

Smoking is another factor that accelerates collagen loss. The chemicals in cigarette smoke reduce blood flow to the skin, impairing its ability to produce collagen. This leads to the skin becoming thinner and more prone to wrinkling.

Additionally, smoking causes damage to the collagen fibers themselves, making them weaker and more brittle.

Other environmental stressors, such as pollution, can also damage collagen. Pollutants in the air can break down collagen and reduce the skin's ability to repair itself, causing premature aging signs like fine lines, wrinkles, and sagging.

The Impact of Collagen Loss on Skin

When collagen decreases, the skin can no longer retain its firmness and elasticity. As a result, the skin becomes more prone to the formation of wrinkles, sagging, and an overall loss of volume. The first signs of collagen loss are usually fine lines around the eyes and mouth, followed by deeper wrinkles and skin sagging. The skin may also lose its natural radiance, appearing dull and thin.

Without enough collagen, your skin struggles to maintain its structure and resilience, and this contributes to the overall aging process. Wrinkles and sagging become more noticeable, and your face might begin to look less full and youthful.

What is Elastin?

Elastin is another incredibly important protein in your skin, and it works alongside collagen to keep your skin looking youthful and healthy. While collagen provides the structure and firmness, elastin is

responsible for the skin’s ability to stretch and bounce back to its original shape. You can think of elastin as the “rubber band” of your skin. When you pull your skin, elastin allows it to stretch and return to its normal position without losing its shape.

The Role of Elastin in Skin Health

Elastin is crucial for maintaining the skin's flexibility. Without it, your skin wouldn’t be able to move freely or retain its smooth, supple appearance. It’s what gives your skin that youthful, bouncy texture. Whether you're smiling, raising an eyebrow, or just turning your head, elastin ensures that your skin moves with you and doesn't sag or wrinkle unnecessarily.

This flexibility is essential in everyday functions like facial expressions, and it also helps your skin maintain a smooth and even surface. Elastin fibers are woven throughout the dermis (the skin’s second layer) and are responsible for its ability to stretch, snap back, and resist the formation of fine lines. Thanks to elastin, your skin can handle everyday wear and tear, returning to its smooth form after every stretch, bend, or pull.

When elastin is in good condition, it contributes to your skin’s natural firmness and elasticity, ensuring that it looks plump, smooth, and youthful. However, as we age, the production of elastin slows down, and the elastin fibers in the skin begin to weaken and become damaged.

How Elastin Declines Over Time

Just like collagen, elastin production also decreases with age. As we get older, the elastin fibers become less resilient and start to lose their ability to stretch and bounce back. This decline usually starts in your late 20s or early 30s and continues over time, contributing to the appearance of wrinkles, sagging, and the overall loss of skin elasticity. The skin becomes less able to snap back into shape, and you may begin to notice that the fine lines and wrinkles become more pronounced. (3)

External factors like sun exposure, smoking, and pollution can speed up this process, making the skin age more quickly. UV rays from the sun, for example, break down elastin fibers in the skin, weakening their ability to provide that natural stretch and flexibility.

This is why sun protection is crucial in any collagen and elastin skincare routine—it helps protect the skin’s elastin from damage and supports the skin’s natural elasticity. Pollution also damages elastin fibers, while smoking reduces blood flow to the skin, affecting its ability to regenerate and repair itself.

When elastin levels drop, the skin begins to lose its youthful resilience. The signs of aging become more visible—think sagging around the jawline, drooping eyelids, and deeper wrinkles. Your skin may look thinner, drier, and less vibrant, as the loss of elastin leads to a more fragile, less flexible surface.

The skin becomes less able to recover from stretching, and wrinkles that once appeared only after facial expressions may now stay for longer periods.

Collagen and elastin are like two best friends working together to keep your skin looking young and vibrant. They each have their own unique job, but they depend on each other to maintain skin’s strength, firmness, and elasticity. Imagine them as the perfect duo that supports your skin’s structure and flexibility, helping it stay resilient to the effects of aging and environmental stress.

How Collagen and Elastin Work Together

Collagen provides the structure and support for the skin. Think of it as the scaffolding that holds everything in place. It keeps your skin firm, smooth, and strong. Collagen is responsible for giving your skin its overall strength, but it’s not enough on its own.

This is where elastin comes in. Elastin is like the elastic band that gives your skin the ability to stretch and bounce back. It provides flexibility, allowing your skin to move, smile, or even stretch without losing its shape.

Together, collagen and elastin maintain the perfect balance of strength and flexibility in your skin. Collagen forms a supportive framework beneath the skin’s surface, while elastin allows the skin to stretch and recover. They work hand-in-hand to keep your skin taut and resilient. When one is lacking, the other can’t do its job as effectively, which is why balanced levels of both are crucial for youthful, glowing skin.

Collagen and Elastin in Action

To really understand how they work together, think about how your skin behaves when you move your face. When you smile or laugh, the skin around your mouth stretches. This stretching is possible because of elastin.

 After the movement, elastin allows your skin to return to its original shape, but it’s the collagen that ensures the skin stays firm and doesn’t lose its tautness. If you didn’t have enough collagen, your skin would lose its firmness, and if you didn’t have enough elastin, your skin wouldn’t have the ability to stretch and recover.

This balance is crucial not just for facial expressions but for the overall appearance of your skin. As we age, the production of both collagen and elastin slows down, leading to changes in how the skin behaves. Without enough collagen, your skin may start to sag and lose its fullness. Without enough elastin, your skin might lose its flexibility, leading to deeper lines and wrinkles. The loss of both proteins can make the skin look less youthful, thinner, and less vibrant.

Why Balanced Levels Are Key

When collagen and elastin are in balance, your skin has the perfect combination of strength and stretch. This balance gives your skin its youthful appearance, keeping it firm, smooth, and flexible. It helps the skin maintain its shape and structure while allowing for natural movement, like laughing or squinting, without the skin losing its tautness or flexibility.

But as we age, both collagen and elastin levels decrease. After the age of 20, we start losing about 1% of our collagen each year. This decline continues over time, making skin appear less firm and more prone to wrinkles. Elastin, too, loses its ability to stretch and bounce back as we age. Without the strength from collagen and the flexibility from elastin, the skin becomes more susceptible to sagging and wrinkling.

How to Support Collagen and Elastin Together

Supporting collagen and elastin doesn’t have to be complicated—just a few key habits can go a long way in keeping your skin firm, elastic, and youthful. Three of the most effective ways to maintain these essential proteins are through vitamin C, sun protection, and supplements. When incorporated into a well-rounded elastin skincare routine, these steps can help maintain skin’s flexibility and resilience.

1. Vitamin C

Vitamin C is one of the best ingredients for preserving both collagen and elastin. It plays a crucial role in collagen production by stimulating fibroblasts, the cells responsible for creating new collagen fibers. Without enough vitamin C, collagen synthesis slows down, leading to weaker, less resilient skin. But that’s not all—vitamin C is also a powerful antioxidant that protects elastin from oxidative stress caused by pollution and UV rays. (4)

Elastin fibers are delicate and can break down easily when exposed to free radicals, leading to sagging skin and wrinkles. Using vitamin C regularly as part of an elastin skincare routine helps prevent this damage while also brightening the skin and evening out its tone. For best results, a high-quality vitamin C serum should be applied in the morning before sunscreen to maximize protection.

2. Sun Protection

Sun protection is one of the simplest yet most effective ways to prevent premature aging. UV rays are the number one external factor that break down collagen and elastin, leading to sagging, fine lines, and wrinkles. Even short-term sun exposure can weaken these proteins, reducing the skin’s ability to stay firm and elastic. The best defense is a broad-spectrum sunscreen with at least SPF 30, applied daily—even on cloudy days.

Sunscreen not only protects existing collagen and elastin but also prevents the formation of free radicals that accelerate skin aging. Wearing protective clothing, seeking shade, and using antioxidant-rich skincare alongside SPF can further enhance elastin skincare benefits.

3. Supplements

Supplements can also be a great way to support collagen and elastin from within. As we age, natural collagen production declines, and dietary supplements can help fill the gap. Collagen peptides are particularly effective, as they are easily absorbed and stimulate the body’s own collagen production. Vitamin C is often included in these supplements to aid absorption and enhance collagen synthesis.

Additionally, certain plant-based extracts, like Tremella fuciformis, have been shown to help maintain skin hydration and elasticity, making them excellent additions to an elastin skincare routine.
