About Gundry MD Dark Spot Diminisher

By HighYa Research Team
Published on: Aug 12, 2016

By “harnessing the power of polyphenols,” Gundry MD Dark Spot Diminisher promises to significantly fade the appearance of dark spots in just a few weeks. How?

According to Gundry MD, Dark Spot Diminisher delivers a “breakthrough” solution to your skin that can address the problem from the inside, helping to reduce the appearance of age spots, sun spots, liver spots, macules, freckles, and more on the outside. Then, its polyphenols can help protect against UV damage and the glycation process (more soon), which can prevent future dark spots from appearing.

And because Dark Spot Diminisher claims to strengthen cell membranes and provide better moisture retention, Gundry MD promises to deliver fresh looking skin for any skin type.

To accomplish this, Gundry MD tells us you only need to apply a dime-sized amount of Diminisher to your dark spots twice daily (once in the morning and again at night), and you could see visible results in as little as two weeks. Perhaps best of all, they claim to only use 100% safe ingredients without any reported side effects.

Even if Dark Spot Diminisher really can help you “take back the glow you deserve,” will it provide the most value for your money? Are there other options that could work just as well, but at a lower price? Let’s start finding some answers to all your important questions.

What Are Dark Spots? How Do They Form?

Age spots can go by many names, including sun spots, liver spots, solar lentigines, and more. Regardless of what you call them though, they’re simply flat brown (sometimes black or grey) spots underneath the skin caused by the accumulation of melanin.

Here’s a good way to think about it: If you spend too much time in the sun, your skin naturally produces more melanin to protect against further UV damage. This is what most of us refer to as a suntan.

After years of sun exposure, this melanin can begin “clumping” together permanently, resulting in age spots, which become more prevalent after we reach the age of 40. This is why sun spots most often appear in areas frequently exposed to sun, such as the face, back of the hands, forearms, and shoulders.

Glycation, AGEs, & Polyphenols, Oh My!

What about the glycation and A.G.E. referenced in the Dark Spot Diminisher video and on their website? Glycation occurs when a protein or lipid molecule bonds with a sugar molecule, resulting in a “haphazard process that impairs the functioning of biomolecules.”

The final result of the glycation process is something known as advanced glycation end products (AGEs), which “are known to contribute to increased oxidant stress and inflammation, [and are] are linked to the recent epidemics of diabetes and cardiovascular disease.”

Polyphenols, on the other hand, are a type of antioxidant found in a variety of foods, which, like most other antioxidants, might have the ability to fight free radicals and reduce instances of cancer and other diseases.

Now, is there anything contained in Dark Spot Diminisher that can fade dark spots or reduce the effects of glycation?

What Ingredients Does Dark Spot Diminisher Contain?

According to Gundry MD’s website, Dark Spot Diminisher contains:

Deionized Water, Propanediol (Vegetable Derived), Diglucosyl Gallic Acid, Vitis Vinifera (Grape) Seed Oil, Squalane (Derived from Sugar Cane), Glycerin (Vegetable Derived), Terminalia Ferdinandiana (Kakadu Plum) Fruit Extract, Butyrospermum Parkii (Shea Butter), Dimethicone, Cyclopentasiloxane, Rhodiola Rosea (Roseroot) Extract, Argania Spinosa (Argan) Kernel Oil, Camellia Oleifera (Green Tea) Leaf Extract, Euterpe Oleracea (Acai) Fruit Extract, Lysolecithin, Oxycoccus Palustris (Arctic Cranberry) Seed Oil, Resveratrol, Diamond Powder, Niacinamide, Polymethylsilsesquioxane, Sodium Acrylate/ Sodium Acryloyldimethyl Taurate Copolymer, Vaccinium Angustifolium (Blueberry) Fruit Extract, Polysorbate 60, Fragrance (Parfum), Ethylhexylglycerin, Caprylyl Glycol, Caprylhydroxamic Acid, Xanthan Gum, Pullulan, Sclerotium Gum, Tetrasodium Glutamate Dictate

Like just about every OTC skincare treatment, the vast majority of Dark Spot Diminisher’s ingredients act as emollients, lubricants, preservatives, and skin conditioning agents. As such, they’re primarily responsible for making the cream feel good against your skin while helping your skin retain additional moisture.

While this is certainly positive, most of these seem to have very little clinical evidence indicating that they’ll address dark spots in any meaningful way.

To this extent, diglucosyl gallic acid is a patented molecule that’s converted into trihydroxy benzoic acid (THBA) by the body’s natural microorganisms, which may even skin tone and lighten pigmentation. However, there doesn’t seem to be any publically available clinical evidence supporting these claims.

The mild caffeine content found in green tea may help temporarily (and very mildly) firm skin, while the diamond powder is an abrasive, supposedly to help exfoliate skin and promote cell turnover.

Finally, Kakadu Plum contains high levels of antioxidants (which we’ve already discussed), as does acai and blueberry.

What conclusions can we draw? Based on the available clinical evidence for each of its ingredients, it doesn’t seem that Dark Spot Diminisher’s formulation would be especially effective for promoting even skin tone or reducing the appearance of age spots.

How Much Does Dark Spot Diminisher Cost?

Dark Spot Diminisher is priced as follows:

  • 1 Bottle: $49
  • 2 Bottles: $86
  • 3 Bottles: $120

Like all Gundry MD products (more about this next), Dark Spot Diminisher comes with a 90-day satisfaction guarantee, less S&H. In order to request one, customer service can be reached at (800) 852-0477.

Does Dark Spot Diminisher Have Any Competition?

Because you’re reading this review, you almost certainly recognize that there are thousands of other products out there claiming to address dark spots in one way or another. In fact, we’ve reviewed many of these popular products here at HighYa, including Beverly Hills MD Dark Spot Corrector, City Dark Spot Corrector, truVitaliti, and Genucel.

Comparatively, how does Gundry MD’s formula stack up?

While their exact formulations can be as diverse as the manufacturers themselves, most dark spot correctors work using ingredients intended to lighten skin, such as hydroquinone, lignin peroxidase, ellagic acid, and more. Conversely, Dark Spot Diminisher uses diglucosyl gallic acid, which appears to have less clinical evidence supporting it than more traditional ingredients.

From a price perspective, most dark spot correctors seem to fall somewhere between $30 and $60, so Dark Spot Diminisher appears to be priced somewhere in the middle.

Who Is Dr. Steven Gundry?

Dr. Steven Gundry is the namesake behind Gundry MD, and has been practicing medicine as a heart surgeon for 30+ years. He’s also Director for The International Heart and Lung Institute in Palm Springs, as well as the Founder for The Center for Restorative Medicine in Palm Springs/Santa Barbara.

According to Dr. Gundry, he founded Gundry MD in order to help customers benefit from a new scientific breakthrough that has allowed literally thousands of people to feel healthier and happier than they ever thought possible.” Exactly what this breakthrough is, we’re not told, but it’s likely something related to polyphenols.

Let’s carry this thought over into the final section.

Will Gundry MD Dark Spot Diminisher Work for You?

In the Gundry MD Dark Spot Diminisher promo video, like many of Gundry MD’s other products (including Primal Plants, Vital Reds, Lectin Shield, and more), the company claims to treat root of the problem from the inside-out. However, since Dark Spot Diminisher is only applied to the surface of the skin, this simply can’t occur.

If Dark Spot Diminisher did actually effect change from the inside-out though, it would be considered a drug (versus and OTC beauty product) and subject to much more intense government oversight.

Next, while polyphenols certainly seem to have some positive clinical evidence showing their ability to reduce free radicals (just like any other antioxidant), it’s not clear exactly how much is needed to accomplish this. Even then, we didn’t come across any evidence indicating polyphenols are especially good at reducing dark spots or preventing UV damage—or that they’re effective at all for these purposes.

In the end, we’re consumers too, and we want to get just as much value for our dollar. Given this, despite the largely positive customer feedback for Gundry MD’s other products, we might talk with our doctor before placing our order.

If you’re intent on ordering though, Gundry MD seems to stand behind their products with a 3-month refund window, which means you might only be out a few bucks in S&H if you’re dissatisfied.

    Grundy MD Dark Spot Diminisher did not work

    • Dallas, TX,
    • Aug 16, 2019
    • Verified Reviewer

    I have used the Grundy Dark Spot Diminisher consistently in the morning and evening for over a month now and I don’t see any improvement to the spots on my cheek, instead, I see the spots look a little darker. I am so disappointed and sad as I had very high hopes.

    Bottom Line: No, I would not recommend this to a friend

    Disappointed

    • Chicago, IL,
    • Aug 15, 2019
    • Verified Reviewer

    I purchased three months worth of this product. It has done absolutely nothing for the spots on my hands, I wrote claiming a refund as per 90-day guarantee, they say I have to return the product for a refund. I don’t have any left, I faithfully used all three bottles as per instructions and recycled the bottles. What’s the point of returning empty bottles? Don’t purchase, it doesn’t work and is very expensive, and the 90-day guarantee is useless as far as I’m concerned.

    Not worth the money

    • North Carolina,
    • Aug 12, 2019
    • Verified Reviewer

    I have tried the Dark Spot Diminisher for over a month now and really don't see change at all to the freckles/dark spots (probably due to sun damage and age) that are on my face. His whole thing in his video on the site about using "meadowsweet" in the formula which is what he touts as his big discovery in making dark spots go away is low on the list of ingredients in the product. I feel scammed and am going to attempt to ask for a refund. I'm skeptical now of ANY product this guy/company has to offer. I believe he is just another person who has figured out that women are insecure about lots of things as they age and is cashing in on those fears by seemingly offering antidotes to combat their aging woes. Take a pass on this.

    It's ok

    • Seattle, WA,
    • Jul 27, 2019
    • Verified Reviewer

    Have used it consistently morning and evening for close to two months. I find that it has faded the six spots on my face but has not totally diminished them and probably won't. My spots are from medication that I take every day as I don't lay out in the sun because my skin is fair and don't want to get burnt. So I can't really say one way or another that this won't diminish the spot from sun.

    I have several areas that have medium/dark spots, arms, and face. I have used this product diligently through 2 bottles and saw very little improvement. I am extremely disappointed as I had very high hopes. I will finish my third bottle and let you know what the results are. Maybe it just takes more...

    Not what I hoped

    • Colorado Springs, CO,
    • Jun 25, 2019
    • Verified Reviewer

    I just finished the 4th bottle that I diligently used twice a day, but I see very little results. Maybe I’m too old (62) for any meaningful change.

    I contacted the company and made sure I was using it correctly. As I had thought you need to let it dry for a while before applying lotions and makeup. The directions don’t actually say that. Even so, I saw very little change in my skin.

    Doesn't work for deep, older spots

    • Seattle, WA,
    • May 14, 2019
    • Verified Reviewer

    I have used this product for almost 50 days according to the instructions (two times a day). I used it on my face on very dark large spots. I also have freckles and medium toned skin. My spots have shifted down (weirdly) and some fading has happened, but not as significantly as I would have liked. I am on a second bottle because I was hoping for more results after long-term use. However, my spots are now darker...not sure what is happening. I use a very good sunscreen and makeup over that to help cover the spots...not working!

    The entire left side of my face turned an awful gray-black mess. I was working and driving across the state multiple times weekly. The sun hit my face through tinted windows and sunscreen.

    I literally stayed home for months. Ugh, it wouldn’t go away.

    I tried this with trepidation but knowing there was a 90-day guarantee, I said all right.

    From the first day, I saw a difference. I got up a few times to check and really thought I was dreaming.

    It’s been a week and every day it gets better and better!

    I’m feeling so relieved.

    Thank you, thank you, thank you Dr. Gundry for all of your time and effort.

    Life changer for me!

    Bottom Line: Yes, I would recommend this to a friend
