A Nudge, Not a Lift: What Collagen Powders, Capsules, Gummies, and Serums Actually Do

Black and white still life of a scoop of collagen powder beside a glass of water and a supplement jar. Commentary on collagen formats by Dr. Frank Agullo, MD, FACS.

Flow Space called this month to do a piece on collagen supplements. When we got on the phone, the interviewer finally asked the real question on everyone’s mind: powder, pill, gummy, or serum; what actually gets absorbed and works for you?

The explanation I gave her was shortened to fit the article. Here is the full one. The formats are not equal, and the gap between the worst and the best is larger than the price suggests.

Powder Wins, and It Is Not Close

There are no other formats in that aisle with enough human data behind them. Only powder. The researchers did not measure mouse models; they did not measure cells under a microscope. They measured human volunteers at the end of human trials.

They study dosages of anywhere from 2.5 to 10 grams of hydrolyzed collagen peptides a day, and those have resulted in measurable, though often subtle, improvement in skin hydration and elasticity over 8 to 12 weeks.

Read it twice. Modest. And 8 to 12 weeks.

Powder wins because the doses in those studies come out of the tub by the spoonful. You can take exactly what the studies used, which happens to be the hardest thing to manage among all the products in this category.

Capsules Are Usually Underdosed

Capsules are not fraudulent. They are just small.

You would need a large number to get close to even the lower end of what is used in the studies. People pick up a two-cap bottle, think they are being proactive, but still end up with a small fraction of the dose used in the trials, with virtually none of the bottles labeled to warn them about that reality.

Just look at the label to know how much you actually have per serving. Go for the real dose and stick with it, rather than fine-tuning something you will abandon in a month anyway. It costs more per gram with less in the bottle.

Gummies Are the Weakest Option, and Sugar Is Why

Gummies push my buttons in two specific ways, and the two go together poorly.

First, you do not get a meaningful dose. How much collagen can you pack into a gummy and still make it taste good and look like a gummy.

Second, and this one is my main point as a surgeon: most gummies contain added sugar. Sugar in the blood drives glycation, which is essentially when excess sugar in your body binds to proteins and stiffens them. One of the body’s proteins, collagen, happens to be sensitive to this, which leads to stiffness and makes repair take longer. After glycation, collagen fibers become less stretchy, brittle, and break easily, losing the elasticity we all want to retain.

It essentially provides you with a collagen-infused product while including an ingredient that destroys the collagen your body possesses. Strange trade-off to make in the name of skin care, wouldn’t you agree?

Format Delivers the studied dose? Evidence behind it My read
Powder Yes, easily Best human data in the category Where I would put the money
Capsule Rarely, without high pill counts Same peptides, wrong dose in practice Acceptable if you take enough
Gummy No Low content plus added sugar Weakest option in the aisle
Serum Not applicable, does not absorb Surface hydration only A moisturizer, priced like medicine

Serums Cannot Reach the Place That Matters

A collagen serum is a hydration product wearing a lab coat.

The collagen molecule is too large to cross the outer barrier and reach the dermis. Collagen synthesis happens inside the dermis, and for the collagen in a serum to get there, it has to travel all the way from outside the skin. However, if the barrier let large molecules like that pass, it would defeat its one job of providing protection to everything below it.

Collagen serum just makes skin appear moisturized because it is holding water in the outermost layer of the epidermis. Skin appears dewy because it is storing and keeping that moisture. For a short amount of time, collagen serum helps skin perform that duty better than it would on its own. When you stop, the effect fades right back out.

If you want to tell your skin to produce new collagen, buy retinoids, decent vitamin C, and peptides. Do not ever buy something just because “collagen” is slapped onto the packaging.

The Menopause Number Nobody Prepares You For

The statistic I gave Flow Space hit me right in the head, since it quantified something many of my patients go through but cannot explain.

The average postmenopausal woman loses anywhere from 25 to 30 percent of her skin’s collagen in as little as five years after menopause, not over a lifetime. Within five years.

Therein lies why women report feeling as if they hit a sudden wall with their skin. It changed rapidly, not gradually, and falling estrogen is a big part of why.

No, you are not adding powder and getting 25 percent of your dermal collagen back. That is the reality. Supplements can support the tissue you have left. They cannot rebuild the structure once it is gone.

The Thing That Beats Every Supplement in the Aisle

The cheapest way to protect the protein that keeps our skin tight and supple is not a pill or powder. It is sunscreen.

UV damage is the number one controllable reason collagen loss happens. It causes enzymes to destroy collagen in the skin and hinders new collagen development. One can eat heaps of collagen every day and undo the benefit simply by spending time outdoors in the sunlight later on.

You top it with your retinoid, vitamin C, a bit more protein so your body gets what it needs to make new collagen, real sleep, no tobacco, and less sugar, which relates to glycation all over again, except now you are eating it with dinner.

All free, all better than anything you can buy by the tub.

Where the Real Collagen Work Happens

When a patient wants a bigger push, we work our way through the epidermis and down into the dermis.

Sculptra, as an example, has been shown to produce genuine collagen over a span of months, not days. Radiofrequency microneedling, and microneedling generally, provides enough controlled injury to encourage remodeling. Resurfacing lasers work at the surface and just below it.

When it is descent and not quality, nothing ingestible touches it. Descent means the thing has moved downward and it has to move back up. That is precisely what a deep plane facelift accomplishes, and no amount of scooping replaces real repositioning.

Mayo Clinic trained, dual board certified, and a 13-time consecutive Castle Connolly Top Doctor, yet not one time in my entire career have I seen any of these supplements make any sort of difference to a person’s jawline. Believe me, I have looked.

So Should You Take It?

Sure, if your bank account and your timeline allow, and if you take it in a delivery system that actually works.

I told Flow Space that collagen is a nudge, not a lift. It is not a facelift in a scoop. But it is good for something, and when a category is choked with things that are good for nothing, that is a real step.

The powder is the one, definitely get some. Wear sunscreen always. And give it three months before you call it. #StayBeautiful.

The Jar Is Marketing, the Ingredient List Is Medicine: What a Collagen Cream Can Actually Do

Black and white close-up of a jar of face cream beside its ingredient list on a bathroom counter. Commentary on collagen creams by Dr. Frank Agullo, MD, FACS.

WOWMD asked me to weigh in on collagen creams for a roundup of the best formulas of 2026. I gave them one sentence that I would tape to every bathroom mirror in America. Look at the active ingredient, not the front of the jar.

The front of the jar sells you a feeling. The back of the jar tells you whether the product can do anything at all.

So let me take my own advice and turn the jar around.

The Word Collagen on the Label Is Doing Almost Nothing

Here is the part the marketing does not want you to sit with. The collagen molecule is large. Far too large to pass through the outermost layer of your skin and reach the dermis, which is where your own collagen is made and where it would need to go to rebuild any structure.

Rub collagen on your face and it sits on top. It does not sink down, find your fibroblasts, and get stitched into your scaffolding. That is not how the skin barrier works, and a barrier that let large proteins pass freely would be a barrier that failed at its one job.

So what does a collagen cream actually do? It hydrates. It holds water in the top layers of skin, and hydrated skin looks temporarily plumper, smoother, and more reflective. That is a real and pleasant effect. It is also a cosmetic one, and it fades when you stop.

Plumped is not rebuilt. A good collagen cream is a very nice moisturizer wearing a lab coat.

The Ingredients That Actually Signal Your Skin to Build Collagen

Now the useful part. Some topicals really do push the skin to make more of its own collagen. They just are not the collagen itself. They are the messengers that tell your fibroblasts to get to work.

Three of them carry the real evidence.

Retinoids come first. Prescription tretinoin and well-formulated over-the-counter retinol are the most studied collagen-stimulating ingredients we have. They speed cell turnover and nudge the skin to lay down new collagen over months.

Peptides come next. The right peptides act as signals, telling fibroblasts to behave as though repair is needed. Not every peptide on a label is doing this, but the category is legitimate.

Vitamin C is the third. It works as an antioxidant and as a required cofactor in your body’s own collagen production. It also brightens, which people notice faster than firmness.

Then there is the supporting cast that makes the whole formula wearable and effective: hyaluronic acid for hydration, niacinamide for barrier and tone, ceramides to seal the barrier, and growth factors where the formula is stable and actually tested.

What it is Front-of-jar promise What it really does
Topical collagen Rebuilds your collagen Sits on top, hydrates, plumps temporarily
Retinoid or retinol Anti-aging Genuinely signals new collagen over months
Peptides Firms and lifts Signal fibroblasts to repair, when well chosen
Vitamin C Brightening Antioxidant plus a real cofactor for collagen
Hyaluronic acid Plumping Draws and holds water, a hydration workhorse

How to Read the Back of the Jar

Flip it over. Ignore the hero word on the front and read the first five or six ingredients, because that is where the meaningful concentrations live.

If a jar screams collagen on the front but the back is mostly water, thickeners, and fragrance, you are buying a moisturizer at a serum price. If you see a retinoid, a credible peptide, or a stabilized vitamin C near the top, the product can earn its keep.

You are not looking for the longest ingredient list. You are looking for the right ingredients high on it.

How to Start Retinoids and Vitamin C Without Wrecking Your Skin

The active ingredients that work are also the ones that can irritate, and irritation is the number one reason people quit before they ever see a result.

So start slow. If your skin is at all sensitive to retinoids or vitamin C, begin two to three times a week, not nightly. Let your skin adapt, then build up as tolerated. A little dryness or flaking early on is normal. A red, stinging, angry face is you moving too fast.

Retinoids at night, vitamin C in the morning, sunscreen every single day. Sun exposure is the fastest way to undo the collagen you are trying to build, so the sunscreen is not optional. It is half the program.

Set Your Clock to 8 to 12 Weeks

Here is the expectation I gave WOWMD, and it is the one that keeps patients from quitting. The most noticeable results are subtle, and they take 8 to 12 weeks of consistent use to show up.

Not eight days. Eight to twelve weeks. Collagen turnover is slow biology, and any product promising a new face by Friday is selling you the hydration bounce and calling it transformation.

Consistency beats intensity. The person who uses a decent retinoid three nights a week for three months beats the person who uses a great one for four nights and rage-quits.

Where Surgery and In-Office Treatments Actually Fit

Creams maintain and refine. They do not lift structure that has already descended, and they will not erase a deep fold.

When a patient wants actual structural change, the tools that reach the dermis are the ones that matter: energy devices like radiofrequency microneedling and lasers, biostimulators such as Sculptra that provoke a real collagen response, and, when the issue is genuine laxity, surgery. Preservation-style facelifting repositions tissue that no cream can reach.

I completed my plastic surgery fellowship at the Mayo Clinic, I am double board certified, and I have been named a Castle Connolly Top Doctor for 13 consecutive years. None of that changes the biology of a cream. It just means I will tell you honestly which of your goals a jar can serve and which ones need something more.

The best skin plans I build usually use both. A smart topical routine for maintenance, and an in-office treatment for the change a cream cannot deliver.

The Point

A collagen cream will not hand you back the collagen you have lost. What it can do is hydrate well, and if it carries the right actives, quietly help your skin build a bit more of its own over a couple of months.

Turn the jar around. Buy the ingredient list, not the label. #StayBeautiful.

The Quiet Way I Treat Aging: NAD Plus, GHK-Cu, and the Peptides I Stand Behind

NAD plus and GHK-Cu copper peptide vials on a marble medspa counter, reflecting the standalone wellness peptide protocol prescribed by Dr. Frank Agullo, MD, FACS, double board-certified plastic surgeon at Southwest Plastic Surgery in El Paso, Texas

There are two types of plastic surgeons when talking about aging. They are the loudest type and the quietest type. The loud type says fillers, then more fillers, then a surgery. The quiet type takes a longer view and plays the game on a cellular level. Better mitochondria, better collagen, better skin, better sleep. Less for the surgeon to do eventually, as the patient ages more slowly.

My career took the loud road. Deep plane facelifts, breast preservation, body contouring. These are real operations on real anatomy you can see from across the room. I am not going anywhere near quitting those. In recent years, though, I have found myself thinking more about the quiet road as well, because the science is finally at a level where I can stand up and discuss it. This is a post on my take on peptides outside the operating room. NAD+ as a tool for daily energy and longevity, GHK-Cu as a skin-quality investment, and the GLOW blend used on patients who are not recovering from surgery but would like to see a bit more of their thirties in their forties.

What a Peptide Is, in Plain English

Peptides are small amino acids in a chain. Insulin is one, oxytocin is another, and human growth hormone is a peptide. Your body makes tens of thousands of peptides each day, sending signals between tissues. The therapeutic peptides we offer on the wellness menu are the man-made counterparts to molecules that your body produces every single day, made at a cGMP pharmaceutical standard and dosed by the milligram.

The dose simply tells the body to do something it already knows how to do: lay down collagen, repair damaged DNA, build new microvasculature, or restore mitochondrial energy. Peptides do not perform the chemistry to do this work, the peptides signal cells to do so. The work is done by the patient’s own cells.

This is the crucial distinction that tells you what peptides cannot do. Peptides cannot bring back a face that has lost over 20 pounds of its volume along with all of its supportive ligaments and muscles. They cannot make a 45-year-old neck look like one at 30. Surgery does this. Peptides cannot replace surgery when surgery is what your body needs. However, they can build the cellular foundation around surgery stronger, both before and after it. And for the patients who do not need surgery just yet, they can extend the length of the runway.

NAD Plus, the Molecule I Take Seriously

NAD+ is the chemical that means nicotinamide adenine dinucleotide. Technically, it is a coenzyme, and it sits on the menu next to peptides as the longevity molecule with the highest evidence. The “nicotin” component refers to its link to the etymology of vitamin B3. This is not related to smoking. I discuss this with patients on every visit.

NAD+ is the cofactor required for the operation of mitochondria, the part of a cell that produces its energy, and it is used by sirtuins, an enzyme family important in DNA repair and cell maintenance. Longevity researchers care about NAD+ because the levels drop as we get older, correlating with visible signs of aging and even hidden ones, and restoring the NAD+ levels in animals restored cellular function. Human studies are younger, more chaotic, but on track in the same direction.

NAD+ infusions are the more common NAD+ formulation patients have heard of. It is what is responsible for the “I felt so amazing after my infusion” posts online. An infusion run too fast will make patients uncomfortable with chest pain, hot flushing, and burning around the neck and head. That is dose and infusion-rate dependent and normal. An infusion run more slowly over 2 to 3 hours will make patients comfortable throughout. We use the slow rate for all of our infusions. The low-dose subcutaneous injection taken at home is maintenance therapy.

When speaking with patients about NAD+, I suggest they look at two separate timeframes: the acute and noticeable lift in energy and mental clarity immediately after an infusion, and the slower, less noticeable cellular improvements over months and years. Patients book their NAD+ infusion because of the former. I prescribe it because of the latter.

GHK-Cu, the Skin Investment That Runs Deeper Than Topical

GHK-Cu, or copper peptide, is glycyl-L-histidyl-L-lysine copper, a three-amino-acid string normally present in human plasma in high concentration, peaking in one’s twenties with a concentration decrease following that point in life. GHK-Cu is the same active compound in many topical copper peptide skin-quality products available on shelves at any dermatology or beauty counter. However, topical GHK-Cu must penetrate the skin’s outermost barrier (the stratum corneum), designed specifically to keep molecules such as this from entering the skin at high enough concentrations to start cell repair and regrowth. Injectable GHK-Cu delivers the peptide at a controlled dose directly to the dermis. It does not have to fight the skin barrier.

GHK-Cu has been shown to trigger more than 300 gene functions related to repair of injured tissue, and to stimulate fibroblasts (skin cells) to create new collagen, new elastin, and support the survival of stem cells of the epidermis (basal stem cells). Copper peptide also demonstrates anti-inflammatory properties and holds results through preclinical research and some early clinical data on hair regrowth, wound healing, the dermal density of skin, and photoaging. There is not a single part of this story that has been fabricated out of thin air by a skincare brand. What has been misrepresented, and is essentially a lie, is the implication that the topical version of GHK-Cu achieves anything remotely similar to the concentrations proven beneficial in studies of GHK-Cu as a treatment.

When GHK-Cu is ordered for wellness (not surgery), it is most often a woman in her early-to-mid forties who follows best practices about sun exposure, knows surgery is not for her at this time, but wishes for her aesthetic plan to use meaningful cellular improvements as well. The blue color is normal, caused by the copper. It is also injected subcutaneously, most often with injections done at home by the patient.

GLOW, Used Outside the Operating Room

GLOW is a mixture of three peptides: GHK-Cu, BPC-157, and TB-500. I covered these peptides in my post on surgical recovery, where their ability to work synergistically to bring about healing (collagen, angiogenesis, and cell migration) is best leveraged. On a wellness, non-surgical front, the thinking is a little different.

In terms of using the blend on an ongoing basis in wellness settings, I most frequently prescribe only GHK-Cu on a cycle basis, rather than the full blend. The effects and benefits attributed to GHK-Cu, namely improved skin and hair quality, are largely a story on its own. The two peptides BPC-157 and TB-500 show literature to be most beneficial for tissue repair, which is exactly what these peptides were designed for. Dosing them as a permanent maintenance medication for a healthy patient without any particular illness is, to me, dosing the patient far past marginal benefit. It would be better to keep the peptides available to be utilized for a genuine wound, injury, tendinopathy, or surgical recovery, where the effects of higher doses are more easily evaluated.

The only exception that would justify use in a wellness, non-surgical patient would be one dealing with a chronic soft-tissue problem, significant chronic inflammation, or who is recovering from a previous injury. In this scenario, the GLOW blend can be of benefit when cycled and used over a fixed course of time. It is important that this discussion take place with the patient on a case-by-case basis.

What Peptides Do Not Replace

Peptides cannot replace the use of SPF, can never replace adequate and consistent sleep, and can never replace what any given individual uses to maintain themselves day to day, such as some combination of sleep, protein consumption, resistance training, sun protection, and not engaging in behavior that will age you faster (such as drinking your liver and face into early aging). A peptide protocol can be layered on top of this foundation. However, peptides cannot be used as substitutes for it. The attempt at the latter will be a waste of money.

Peptides also are incapable of replacing surgery when the actual physical structure and tissue of your face need it. A patient who has experienced loss of volume along the cheeks and jawline in a way that takes decades off their appearance is not going to achieve a return of these areas with a peptide treatment, regardless of what it may offer. In this scenario, the appropriate course of action is a deep plane facelift, done well, and peptides can serve as support for the recovery process and longevity afterward, not as an outright replacement for it.

The Cautious Side, in Plain Language

It is essential to note that peptides are not under the regulatory process known as FDA new drug approval. Instead, they are compounded at US 503A pharmacies by a licensed and registered physician, and, as I said, there are gray-market options for peptides with questionable identities and origins. This is because a great percentage of the time, such products have not been formulated in a sterile and consistent environment. My clinic partners exclusively with a US-based pharmacy that adheres to cGMP regulations and provides a certificate of analysis with each batch. While my costs will likely be higher than many other sources of peptides you may encounter (on places like Instagram or Telegram), that extra expenditure is, without a shadow of a doubt, why you should stick to a trustworthy source. Do not buy peptides from Instagram. Ever.

For peptides such as growth-factor peptides (a related category of growth factors and signaling molecules), active malignancy is a contraindication to treatment. Pregnancy and breastfeeding are also off the protocol. For patients with a prior personal history of cancer, we will have an extended conversation, and in most instances we will request that an oncologist sign off on treatment. For patients who are anticoagulated for medical reasons, doses will be adjusted in coordination with their cardiologist to maintain patient safety.

Fillers are a tax. That is the way I think of them when it comes to cosmetic procedures. I like and use fillers all the time for the right patient, but the comparison stops there. Peptides differ, in that they do the work that the body already knows how to do, and once you stop peptides, your body just continues on with its own pace of aging. There is no rebound effect, no dependency, and no need to keep dripping peptides for the remainder of time. Used judiciously for specified periods, with a physician defining the dosage and the length of treatment, these can indeed be a valuable longevity tool. However, for patients who wish to continue with the peptides forever, with no rhyme or reason to their prescription, the situation is far more murky.
