Collagen is the protein that gives skin its structure, firmness and bounce. Think of it as the scaffolding beneath the surface: when the framework is full and well-organized, skin looks supported and smooth. As that framework thins, the signs we link with aging start to show.
Microneedling has become a highly requested treatment at our Denver-area practice because it does not try to cover up that change. It prompts your skin to rebuild the collagen it has been losing. Here is what happens beneath the surface and why treatment produces naturally youthful results.
Why Aging Skin Runs Low on Collagen
Collagen and elastin work as a pair. Collagen supplies structure and strength, and elastin gives skin the ability to stretch and snap back. Your body makes plenty of each when you are young, but output starts to slow in your mid-20s and keeps declining from there. The change is quiet at first. Over time, fine lines and wrinkles settle in, pores look larger and the firmness you once took for granted gives way to skin laxity.
The sun pushes the process faster. Ultraviolet light switches on enzymes that break existing collagen apart quicker than the body can replace it, which is a major driver of what shows up as photoaging. That pressure is stronger in Colorado, where a mile of elevation means a thinner atmosphere and a heavier UV load year-round. Consistent sun protection is the smartest way to hold on to the collagen you have, and we break down the specifics in our guide on how to prevent sun damage. Microneedling works the other side of the ledger, helping restore what time and sun have worn down.
How Microneedling Gets Collagen Going
Microneedling uses a device fitted with very fine needles to create thousands of tiny, controlled channels in the skin. Each one is precise: deep enough to reach the dermis, the layer where collagen-producing cells do their work, yet small enough to leave the surrounding tissue intact. The skin interprets those channels as minor damage to fix, and the fixing is where new collagen comes from.
As soon as the channels form, the body starts its natural wound-healing process. Cells called fibroblasts move into the treated zone and begin manufacturing fresh collagen and elastin. A narrative review of microneedling published in Cureus describes how the same process recruits growth factors and encourages new blood vessels to form, which together thicken the skin and support its firmness and elasticity over time. Because microneedling triggers your own biology rather than stripping away a layer with heat or acid, it tends to be well tolerated across a wide range of skin tones.
From Repair Collagen to Lasting Structure
New collagen does not show up finished. In the first days after a session, the body lays down Type III collagen, a soft and temporary version that works like a quick patch over the repair site. Across the following weeks and months, it steadily remodels that patch into Type I collagen, the dense and well-ordered protein that gives healthy adult skin its strength. This is the reason microneedling rewards a little patience. The firmer texture most people notice around the three-month mark reflects collagen that has had time to mature, not a same-day result. It is also why a series of sessions tends to outperform a single visit, since each round adds to the structure while the previous one is still remodeling.
This shift is well documented. In a microneedling review published in Clinical, Cosmetic and Investigational Dermatology, AboutSkin’s practice director, Dr. Joel L. Cohen, and his co-author note that over weeks to months the newly formed Type III collagen matures into Type I collagen, producing visible skin tightening and softer lines.
Here is the rough sequence your skin moves through after each treatment:
| Phase | Timeframe | What Your Skin Is Doing |
| Inflammation | First 24 to 72 hours | Repair signals switch on; mild redness, similar to light sun exposure |
| Proliferation | Days to a few weeks | Fibroblasts build new collagen, elastin and tiny blood vessels |
| Remodeling | Weeks to months | Soft Type III collagen matures into firmer Type I collagen |
A practical review in Dermatologic Surgery found that microneedling delivers real clinical improvement in fine lines and scars with limited recovery, which positions it as a gentler alternative to more aggressive resurfacing.
The Team Behind Your Treatment
Outcomes depend on technique, needle depth and the person running the device, so microneedling at AboutSkin Dermatology and Aesthetics is performed by experienced providers. Our Board-Certified Dermatologists, licensed aestheticians and aesthetic practitioners are all highly qualified to perform the treatment. At your consultation, one of our Board-Certified Dermatologists evaluates your skin to confirm microneedling fits your concerns and your skin type.
Practice director Dr. Joel L. Cohen is fellowship-trained in lasers, has authored more than 336 medical articles and book chapters, and has led over 100 clinical trials on aesthetic devices. He is a Castle Connolly and 5280 Magazine Top Doctor, and our practice has earned a World’s Leading Clinic certification awarded only after independent review.
“Microneedling works with the skin’s own repair machinery instead of against it,” Dr. Cohen says. “The art is setting the right depth and the right plan, then letting the biology do what it already knows how to do.”
When a concern calls for deeper stimulation, we can combine microneedling with radiofrequency energy through Morpheus8, which carries the collagen response further below the surface.
Give Your Collagen a Comeback
Your skin never forgot how to make collagen. It just needs the right nudge, placed at the right depth by someone who does this all day. Call our Greenwood Village office at 303-756-7546 or reach us online to find out what microneedling can do for you, right here in the Denver area.
