How Collagen and Elastin Keep Your Skin Looking Youthful

You’ve probably seen the word “collagen” splashed across the labels of serums, supplements, and powders. It’s become one of those buzzwords that gets repeated so often it starts to lose meaning.

But collagen, along with its lesser-talked-about partner elastin, plays a central role in how your skin looks and behaves. Understanding what these proteins do and what happens when your body produces less of them makes it a lot easier to understand why certain skincare approaches work and others don’t.

At Eze Health Center in Waldorf, Maryland, Chinyere Eze, MS, PA-C, and our team help patients understand the science behind their skin’s changes so they can make informed decisions about care and treatments to keep your skin looking youthful. Here’s what you need to know.

Collagen is your skin’s structural foundation

Collagen is a protein, the most abundant one in your body, and it makes up roughly 75%-80% of your skin’s dry weight. Think of it as the scaffolding beneath the surface — it gives your skin its firmness, thickness, and overall structure. 

Your body produces collagen naturally, but production slows considerably starting in your mid-20s. Several factors accelerate that loss beyond what aging alone accounts for:

• Prolonged ultraviolet (UV) exposure without sun protection
• Smoking
• High-sugar diets
• Chronic stress
• Pollution and environmental damage

When collagen is plentiful and healthy, skin looks full and smooth. When it starts to break down, your skin can become thin and crepey.

Elastin keeps your skin snapping back

Elastin doesn’t get as much attention as collagen, but it’s equally important. As the name suggests, elastin gives your skin its elasticity, the ability to stretch and return to its original position. Pinch the skin on the back of your hand and watch it spring back — that’s elastin doing its job.

Like collagen, elastin production slows with age. Unlike some other proteins, elastin has very limited regenerative capacity. Your body produces most of it during childhood and adolescence, and once it’s gone, it’s difficult to replace. 

This is why sagging and loss of skin resilience become more pronounced over time, particularly around your jawline, neck, and under your eyes.

How collagen and elastin work as a team

Collagen provides structure and density; elastin provides flexibility. When both are functioning well, skin is firm but supple. As both decline, skin becomes thinner, looser, and more prone to fine lines and wrinkles.

Building a routine that protects your collagen and elastin

You can’t stop the natural aging process, but you can slow down the preventable loss and support your skin’s ability to maintain what it has.

Sun protection

Daily broad-spectrum SPF is the single most impactful step. Wearing it every day, including on cloudy days, reduces the cumulative UV damage that breaks down both collagen and elastin over time.

Retinoids

Retinoids are among the most well-studied topical ingredients for stimulating collagen production. Prescription-strength tretinoin has the strongest evidence behind it, though over-the-counter retinol products can also provide real benefit with consistent use.

Vitamin C

Vitamin C serums help neutralize the free radicals that break down collagen, and they support your skin's natural collagen synthesis process at the same time. Look for stable formulations with L-ascorbic acid for the best absorption and efficacy.

TempSure® Envi

For patients looking to improve their skin’s responsiveness, Eze Health Center offers skin rejuvenation with TempSure Envi. This noninvasive radiofrequency treatment stimulates new collagen and elastin growth beneath the skin’s surface as the radiofrequency energy generates heat, tightening the skin from within.

Sessions take about 30 minutes, require no downtime, and work on all skin types. 

When to talk to a provider about collagen and elastin loss

If you’re noticing increased skin laxity, loss of firmness, or fine lines that topical products can’t keep pace with, we can help you figure out the right next step. Call Eze Health Center at 240-219-6889 or send us a message online to schedule an appointment.
