Do Collagen Products Really Work? Creams, Powders & Lasers

Y’all, collagen is everywhere! It is in our creams, serums, supplements, coffee, smoothies, gummies, and some pretty pricey beauty devices. Every product seems to promise plumper skin, fewer wrinkles, stronger nails, healthier joints, or all of the above.

But do collagen products really work? More importantly, which ones are actually worth our money? The truth is not as simple as “collagen works” or “collagen is a scam,” because a collagen cream, a scoop of collagen powder, and an at-home laser work in completely different ways. Let’s put those claims under a very bright bathroom light! I’ve been working on this post for months, and I did the research so you don’t have to.

What Is Collagen, and Why Do We Lose It?

Collagen is not just a beauty buzzword! It is the body’s most abundant structural protein, providing strength and support to our skin, cartilage, bones, tendons, ligaments, blood vessels, and other connective tissues. Think of it as part of the framework that helps hold everything together.

As we age, our bodies gradually produce less collagen, and the collagen we already have becomes weaker and more fragmented. For women, the drop in estrogen during menopause can accelerate collagen loss, while sun exposure, smoking, and excess sugar can break it down even faster. (Here’s a helpful overview of collagen and aging.)

In our skin, that loss can lead to wrinkles, sagging, thinning, and slower healing. Throughout the rest of the body, declining collagen can contribute to stiffer tendons and ligaments, reduced joint cushioning and mobility, and less structural support in our bones. Not every wrinkle or aching knee is caused by a “collagen deficiency,” and taking a scoop of collagen cannot automatically reverse these changes. Still, understanding collagen’s role throughout the body helps explain why this conversation is about much more than skincare.

Do Collagen Creams Really Work?

Here is the problem with traditional collagen creams: A full collagen molecule is enormous! Skin researchers commonly use something called the “500 Dalton rule” as a guideline for skin penetration, meaning molecules larger than about 500 daltons generally have difficulty crossing the skin barrier. A native collagen molecule is roughly 300,000 daltons. That is not a close call! (You can read the research here.)

In other words, intact collagen in a cream is not slipping through the epidermis, settling into the dermis, and filling in our wrinkles. That does not make collagen creams completely useless. Collagen can help hydrate the skin’s surface, making it feel softer and look smoother or plumper temporarily. A good hyaluronic acid serum (I haven’t tried that one, but it’s widely considered the best!), or an inexpensive ceramide moisturizer can provide similar hydrating benefits without claiming to replace lost collagen.

Kiehl’s 1cc CollaShot Plumping Serum

Kiehl’s 1cc CollaShot Plumping Serum takes a more innovative approach by using smaller recombinant collagen polypeptides and what the company calls a “Supra-Liposomal” delivery system. Kiehl’s reports improved plumpness after eight weeks and improved cheek sagging after 12 weeks, but its own fine print says the ingredients reach the skin’s upper or surface layers, not the dermis. I have used it, but not consistently enough to give you a fair personal verdict. For now, I would consider it an intriguing plumping serum and an optional splurge, not a proven way to replace collagen deep within the skin.

You will also see peptide serums marketed as “collagen boosters.” These products do not deliver new collagen into the skin. Instead, certain peptides may signal the skin to produce more of its own, although evidence varies by peptide and formulation. I would prioritize the better-established collagen-supporting ingredients we will discuss below, especially retinoids, vitamin C serum, and daily sunscreen.

Are Cosmetics Regulated by the FDA?

You have probably heard that cosmetics aren’t regulated by the FDA, but that’s not quite accurate. The FDA does regulate cosmetics, although most cosmetic products and ingredients do not require FDA approval before they are sold. Companies must sell safe, properly labeled products, and their labeling cannot legally be false or misleading. (The FDA explains its authority over cosmetics here.)

Still, phrases such as “clinically tested,” “visibly plumps,” and “supports collagen” may be based on small company-sponsored studies, consumer questionnaires, or improvements in surface hydration. “Clinically proven” does not automatically mean that a large, independent study proved the product rebuilt collagen in the dermis. This is where reading the fine print matters!

Should Women Take Collagen Supplements?

When we swallow collagen, it does not travel intact from our coffee directly to our crow’s feet! Wouldn’t that be convenient? During digestion, hydrolyzed collagen breaks down into amino acids and smaller peptides. Some of those peptides can be absorbed into the bloodstream, but our bodies ultimately decide where to use them.

Some studies have reported modest improvements in skin hydration, elasticity, and wrinkles after eight to 12 weeks of collagen supplementation. However, a 2025 review of 23 randomized trials found that while the combined results looked favorable, the benefits disappeared when researchers considered only higher-quality studies or studies that were not funded by industry.

Collagen supplements are also promoted for joint mobility, bone strength, hair, and nails. Some studies have found modest improvements in joint pain and function, and one 12-month study of postmenopausal women found improved bone mineral density with a specific collagen peptide product. However, different collagen formulations are not interchangeable, and the evidence for hair, nails, and gut health is much weaker. Collagen may offer some support, but it cannot rebuild cartilage, treat osteoporosis, or replace strength training, complete protein, and appropriate medical care.

That does not prove collagen supplements never help. It does tell us that the evidence is less convincing than many supplement companies would like us to believe. I still use a collagen peptide powder, but I consider it an optional supplement rather than a must-have or a fountain of youth.

What Is Collagen Powder Made From?

Most collagen supplements are made from animal connective tissue. Bovine collagen usually comes from cow hides, marine collagen is generally made from fish skin or scales, porcine collagen comes from pigs, and chicken collagen commonly comes from cartilage. Multi-collagen powders may contain several of these sources, so anyone with food allergies or dietary restrictions should read the label carefully.

Products marketed as vegan collagen usually contain nutrients that support the body’s own collagen production rather than actual collagen. Recombinant collagen, like the topical ingredient Kiehl’s uses, is a separate category made through fermentation technology.

How Do You Choose a Good Collagen Powder?

Collagen products are regulated as dietary supplements, not drugs, and the FDA does not approve them before they reach the market. (Here is a helpful explanation of supplement oversight.) That makes label transparency and third-party testing especially important.

I look for a clearly identified collagen source, hydrolyzed collagen peptides, the amount of collagen listed per serving, independent testing or certification, and a short ingredient list. I would avoid mysterious proprietary “beauty blends” that don’t disclose how much collagen they contain. Taste and texture matter too, because even the most impressive supplement won’t help if it sits untouched in the pantry!

Collagen is not a complete protein, so I would not use it as a replacement for dietary protein or a complete protein powder. For most healthy adults, collagen is generally well tolerated, but digestive discomfort and allergic reactions are possible. Check with your healthcare provider if you have kidney or liver disease, food allergies, protein restrictions, are pregnant, or take medications that could affect supplement safety.

And yes, you can put collagen in hot coffee or tea! Normal coffee temperatures will not make the amino acids disappear.

The Collagen Powders I Use

Vanilla Naked Collagen Creamer | Cozy Earth Bamboo Stretch-Knit Sleep Dress (in “Blossom”) – lots of color options (Use code CE-EMPTYNEST for 20% off) | Heart Mug

I have been using Vanilla Naked Collagen Creamer for about a month, and I really like it! I love the vanilla flavor, and its ingredient list is refreshingly short. The company identifies its bovine collagen source and lists NSF certification and contaminant testing on the product page. If you want the simplest possible version, Unflavored Naked Collagen contains only bovine collagen peptides.

One month is not long enough for me to claim dramatic skin results, but the flavor and simple ingredient list make the vanilla version easy to use consistently. It is a strong option for anyone looking for a straightforward flavored collagen powder without a lengthy list of added ingredients.

I have also used Physician’s Choice Collagen Peptides for nearly 10 years. It contains grass-fed bovine collagen peptides along with a digestive-enzyme blend, and I originally chose it because it was hydrolyzed, easy to add to my morning tea or smoothie, and readily available on Amazon.

The company markets the added enzymes as helping with absorption. I wouldn’t assume that automatically makes it superior to every other hydrolyzed collagen product without comparative research! Both products are good options, but I especially like the short ingredient list and flavor of Vanilla Naked Collagen Creamer, while Physician’s Choice Collagen Peptides has the advantage of being a product I’ve used for nearly a decade.

Does the NIRA Pro Laser Build Collagen?

NIRA Pro 3 Laser (Use code SUZY_10 for 10% off)

This is where the collagen conversation changes. The NIRA Pro 3 Laser doesn’t try to push collagen molecules through the skin’s surface. It uses a 1450-nanometer laser to create controlled heat in the dermis, where our collagen-producing cells are actually located. The goal is not to penetrate past the dermis, because the dermis is the target.

That controlled heat is intended to stimulate the skin’s natural repair and remodeling response. This is a much more biologically plausible way to affect dermal collagen than rubbing intact collagen onto the surface.

NIRA markets the device as FDA-cleared, and the FDA database lists the NIRA Beauty Skin Laser as cleared for treating wrinkles around the eyes. (You can read the FDA clearance here.) Remember that FDA-cleared does not mean the FDA has endorsed every marketing claim or every possible treatment area. Clearance is tied to a specific device and indication.

You know I love mine, and I use it consistently every single night. (Just ask Bob!), and they’ve worked for me. I documented my experience and results in my NIRA Pro 3 Laser review and my original NIRA 90-day results post. The key word is consistently, because collagen remodeling takes time! This isn’t an overnight fix, but of all the products in this post, the NIRA Pro Laser offers one of the most credible ways to stimulate collagen where it matters.

The NIRA Pro 3 Laser is an investment, but I think it is worthwhile for women who will commit to using it regularly. Empty Nest Blessed readers can use code SUZY_10 for 10% off.

What Actually Helps Protect and Build Collagen?

If your goal is firmer, healthier-looking skin, the first product I would buy is a broad-spectrum SPF 30+ sunscreen! UV exposure breaks down collagen, and a randomized trial found that people assigned to daily sunscreen use showed less skin aging over 4.5 years than those who used it at their discretion. (Read the sunscreen study here.) If we buy collagen products while skipping sunscreen, it’s like filling the bathtub without turning off the faucet!

Supergoop Unseen Sunscreen SPF 50 | Supergoop’s Bright-Eyed Mineral Eye Cream SPF 40

My favorite everyday facial sunscreen is the award-winning Supergoop Unseen Sunscreen SPF 50. Its clear, velvety formula feels lightweight, leaves a natural, non-greasy finish, and works beautifully under makeup. I also use Supergoop’s Bright-Eyed Mineral Eye Cream SPF 40 around my eyes. It’s a mineral brightening, tinted daytime eye cream with caffeine and probiotics that helps reduce the look of puffiness while protecting the delicate eye area from sun damage.

Daily UV protection is one of the best ways to preserve the collagen we already have, and I’m happy to wear both products consistently. When it comes to protecting the collagen you already have, one of the best investments you can make is a sunscreen you’ll actually wear every day!

Counter Retinatural+ Advanced Super Serum

Next, consider a proven retinoid, retinol serum, or retinal serum. Prescription tretinoin has decades of research behind it, and one human study found increased collagen formation in photodamaged skin after 10 to 12 months of treatment. (Read the study here.) Over-the-counter retinol and retinal products are generally gentler, but the best choice depends on your skin and tolerance. I use THIS 0.50 retinol product on my hands before bed every night, and THIS 0.25 retinol product on the rest of my body.

A well-formulated vitamin C serum is another smart addition because vitamin C supports collagen synthesis and helps protect the skin from oxidative damage. Pair it with a good daily facial sunscreen, and use a hydrating night cream or barrier-supporting moisturizer to help your skin look smoother and healthier.

What About Other At-Home Beauty Devices?

One other at-home device category deserves a place in the collagen conversation: red and near-infrared LED therapy. Unlike microcurrent devices, LED therapy has a credible connection to collagen production because the light may stimulate fibroblasts, the cells that produce collagen and elastin. In one controlled clinical trial, participants saw improvements in fine lines and skin roughness along with increased collagen density after 30 treatments.

I use the CurrentBody Skin LED Face Mask and CurrentBody Neck and Décolletage LED Mask, which deliver red and near-infrared wavelengths similar to those studied for skin rejuvenation. I consider LED a gentler, more gradual collagen-supporting option than the NIRA Pro Laser, and consistency is essential. Empty Nest Blessed readers can use code SUZY10 for 10% off CurrentBody. You can read my post about red light therapy HERE.

I would not recommend at-home microneedling devices for collagen production. The FDA says it has not authorized any microneedling medical devices for over-the-counter sale and warns about risks including infection, pigment changes, and scarring. (Read the FDA guidance here.) This is one area where professional guidance matters.

The Bottom Line

My collagen arsenal: Supergoop Unseen Sunscreen SPF 50 | NIRA Pro 3 Laser (Use code SUZY_10 for 10% off) | Counter Retinatural+ Advanced Super Serum | Kiehl’s 1cc CollaShot Plumping Serum | Supergoop’s Bright-Eyed Mineral Eye Cream SPF 40

Collagen itself is not hooey. The hooey begins when every product containing the word “collagen” is treated as if it does the same thing. A collagen cream can hydrate and temporarily plump the surface, while a recombinant collagen serum may offer more sophisticated surface benefits. A collagen supplement provides peptides and amino acids the body may use, but the evidence for visible skin benefits is mixed. A laser uses controlled heat to stimulate the body’s own response inside the dermis, which is a completely different proposition.

My top collagen investments would be a daily facial sunscreen, a proven retinoid or retinol, a good vitamin C serum, and the NIRA Pro 3 Laser for women ready to invest in an at-home device. I consider collagen powder optional, traditional collagen creams part of the moisturizer category, and Kiehl’s CollaShot Serum an intriguing option that I’m committed to using.

I hope you enjoyed this post and learned a lot! I learned so much while putting it together, and the research made me feel much more confident about which products can truly help. I hope you feel the same! Now that you know what really supports collagen, you can make smarter choices, invest in products that deserve a place in your routine, and feel good about skipping the rest. What did you learn, and which product or treatment are you most interested in trying? Tell me in the comments!
