Gundry MD Dark Spot Diminisher Review: A Detailed Look

By Lydia Noyes

Updated on: Apr 30, 2020

The Gundry MD Dark Spot Diminisher claims to combat many forms of skin discoloration, including age spots, sun spots, and liver spots. This advanced serum promises to transform a blotchy, uneven skin tone to restore your skin and give you a more youthful appearance.

Dr. Gundry is an American doctor and author who formerly worked as a cardiac surgeon. He’s written numerous books on holistic wellness through a better diet and has released a line of supplements and skincare products designed to keep you looking young and feeling healthy.

The Dark Spot Diminisher’s formula contains a range of ingredients that will purportedly improve your skin’s health without adverse side effects, meaning that you can use it for the long term.

These claims aren’t unique within the anti-aging skincare industry. Does the Gundry MD Dark Spot Diminisher stand out from other options? Our analysis of this premium product will help you decide if it is a good option for you.

How to Use It

The Gundry MD Dark Spot Diminisher is a skincare serum designed for twice-daily use. The company suggests you apply it to your trouble spots twice daily in the morning and evening.

You can start by applying a dime-sized amount to your dark spots and surrounding areas, massaging it into your skin with gentle circular motions.

Make sure you leave it on for as long as possible before showering or otherwise rinsing it off so that the active ingredients have time to work.

Analysis of Ingredients

Many of the ingredients in the Gundry MD Dark Spot Diminisher act as emollients, exfoliants, skin lightening agents, humectants, thickening agents, preservatives, natural sources of antioxidants, and other skin conditioning agents.

A few deserve a second look.

Bacillus ferment is an enzyme-based skin exfoliant that is used as an alternative to alpha hydroxy acid (AHA), a class of compounds that are often used to plump and smooth the skin while visibly brightening dark spots. Some people experience adverse side effects from AHA’s like burning, itching, or even blisters, so bacillus ferment is often used as a milder alternative with less risk of irritation.

Diglucosyl gallic acid, also known as trihydroxy benzoic acid alpha-glucoside, is a patented molecule that’s used to lighten skin pigmentation and brighten your overall skin tone. It can reduce dark spots and prevent new ones from forming.

Sodium hyaluronate is a common ingredient in anti-aging products because it will purportedly increase your collagen production to improve your skin’s elasticity and fill in fine lines and wrinkles. Clinical evidence shows that it will work as described, but only when taken as injections. There’s less evidence right now that it will work when used topically in a skin cream.

Diamond powder is often added to skincare products, both to increase their perceived value and to act as a natural exfoliant. The powder is commonly used as a brightener to disguise fine lines and wrinkles by reflecting light off your skin. However, this ingredient is listed low in the Gundry MD Dark Spot Diminisher, so you shouldn’t assume there’s much in it.

Finally, the serum includes a range of plant extracts that are known as polyphenols. Renowned for their high antioxidant content, polyphenols applied topically are considered an effective way to combat some of the causes of aging skin, including environmental damage and free radical exposure.

Overall, many ingredients in the Gundry MD Dark Spot Diminisher show promise for working as described to moisturize your skin and lighten your dark spots.

Possible Side Effects

According to the company website, all Dark Spot Diminisher ingredients are 100% safe for topical use and won’t lead to skin irritation when used correctly.

We didn’t uncover any known side effects throughout the research process, and in at least one case—bacillus ferment—a milder version of a popular ingredient is used to reduce irritation further.

If you tend to have sensitive skin, it’s still a good idea to perform a patch test before using this product. Dab a small amount on your arm and watch how your skin responds over 24 hours before applying it to your face.

Pricing and Money-Back Guarantee

Gundry MD Dark Spot Diminisher is currently listed on the company’s official website at the following prices:

  • One Bottle: $120
  • Two Bottles: $228
  • Three Bottles: $324

However, we also found an “internet only promotion” offer from the company where the same-sized bottles of Gundry MD Dark Spot Diminisher cost the following:

  • One Bottle: $49
  • Two Bottles: $86 ($43 each)
  • Three Bottles: $120 ($40 each)

In other words, you may want to shop around.

Shipping seems to be free for all purchases, and you can expect two to seven-day delivery.

All orders from the company website qualify for a 90-day money-back warranty that comes into effect on the day you make the purchase. Keep in mind that purchases from other retailers such as Amazon don’t qualify for this refund and that you’ll need to pay any return shipping costs.

You can initiate this process by contacting customer service at (800) 852-0477 or support@gundrymd.com.

Analysis of Customer Reviews

We have almost 500 reviews of the Gundy MD here at HighYa, and the product has averaged an impressive 4.2 stars, with 89% of users saying that they would recommend to it a friend. Here’s a closer look at what these customers want you to know:

Common Compliments:

  • Began to reduce dark spots within a week of use
  • Left hands looking younger after treatment
  • Works well if you prep your skin beforehand

Common Complaints:

  • Didn’t work as promised to lighten dark spots, even after months of use
  • The scent was too strong for some users
  • Results were too subtle for the cost
  • Left a reddish tone on some user’s skin
  • Some experienced delayed shipping

Popular Alternatives

Plenty of options are available today, promising to restore your skin and even out its coloring. Here’s a summary of how it compares to two popular products: the Beverly Hills MD Dark Spot Corrector and the City Beauty Illuminating Dark Spot Corrector.

Gundry MD Polyphenol Dark Spot Diminisher Beverly Hills MD Dark Spot Corrector City Beauty Illuminating Dark Spot Corrector
Cost $120 per bottle (1-oz) $129.95 per bottle (1-oz) $72 per bottle (1-oz)
Key Ingredients Bacillus ferment, Diglucosyl gallic acid, Sodium hyaluronate, polyphenols Kakadu Plum, DermalRx, Daisy Flower Extract, Niacinamide Alpha Arbutin, Sepiwhite-MSH, Resveratrol
Average HighYa Rating 4.2, 89% would recommend to a friend 4.5, 89% would recommend to a friend 4.3, 89% would recommend to a friend

As this chart shows, both the Gundry MD and Beverly Hills MD dark spot treatments cost approximately the same amount, at over $120 per 1-oz bottle. The City Beauty Illuminating Dark Spot is comparatively affordable at almost half the cost.

What’s interesting is that all three products rely on significantly different ingredients to achieve the same aim—fading dark spots on the skin. One consistency between them is that each contains a plethora of plant-based ingredients that act as natural sources of antioxidants and polyphenols to improve your skin naturally.

Each has also earned a stellar review from HighYa readers, averaging more than four stars and close to nine out of 10 readers recommending them to others.

In our estimation, this means that you can’t go wrong with experimenting with any one of these dark spot removers. Each company also offers a no-questions-asked return policy, so you will only be out the cost of shipping if you decide it isn’t right for you.

The Bottom Line: Is It Worth It?

Overall, the Gundry MD Dark Spot Corrector seems to be a viable option for improving your skin and fading dark spots. None of the product’s ingredients raised any red flags from a safety standpoint, and many show clinical evidence for improving your skin texture and tone so that you look younger.

One thing to be aware of is that this product seems to be sold at wildly varying price points across the web – even from the official company. We found savings of almost 60% per bottle on different websites, so we recommend shopping around before committing either way.

The Gundry MD Dark Spot Diminisher was a positive purchase for many reviewers, and there’s a good chance that you will have a similar experience. Just keep in mind that there are plenty of similar products available that will likely deliver the same level of results, so it’s worth shopping around.

By golly, spots almost gone!

By Cheryl B., Tampa, FL, Verified Reviewer

I have had dark spots and blotches on the back of my hands, which were very embarrassing for me, making me feel very old (thanks to the Florida sun). I tried many different things over the years, but nothing seemed to help, except covering them up with waterproof makeup. Then I started to use the Gundry MD dark spot remover on my hands every morning and every night, wherever the dark spots and splotches were on the back of my hands. The formula immediately made my hands smoother and evened out my skin color. Those awful dark spots, though, did not fade immediately. Within 1 week, I noticed a difference in my right hand, but not so much in my left hand. It was encouraging, though, to see some improvement. I kept using it day and night, and within 3 weeks, most of the dark spots were fading slowly on my right hand. But my left hand not as much, although they looked better. I continue to use the formula, and after 1 month, they are pretty much gone on my right hand. I'm still hoping for improvement on the other hand. I think the Gundry MD dark spot remover is the best I have tried so far, and I will continue to use it. It has a lovely clean fragrance, and does not irritate your skin. I loved how it immediately evened out my skin color on the backs of my hands, and pretty much completely faded the dark spots on my right hand in about a month's time. I dont know why my left hand did not respond as well to the treatment. But I'm not giving up. Oh, and did I tell you I am 72 years old? You're never too old to feel beautiful again.

Length of Use: Less than 3 months

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

Pros and Cons

Evened out my skin color

Faded my dark spots, but not entirely

Does not irritate my skin tone

Has a nice, clean scent

Did not completely fade my dark spots

It is somewhat sticky

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

Makes my face feel smooth

Like the even tone I was starting to have on my face

It does help the spots

By Marlene H., Prospect, KY, Verified Reviewer

I am on my 4th bottle. I see a good improvement on my face. I had a very dark spot near my left eye and that is starting to get smaller. I had a growth on the right side of my neck area. Was removed years ago by my dermatologist. It came back. Using the MD Dark Spot Diminisher it is getting smaller. My skin does not feel dry at all. I have been using a moisture cream when I put on foundation. Do not wear foundation every day. I am 85 years old. Moisturizer is a question that I have. Should one put a day and night moisturizer on each day over the diminisher?

Length of Use: Less than 3 months

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

Pros and Cons

That the spots are getting smaller

Skin feels smooth

Appearance of skin looks better

The cost of it

The time it is taking to reduce the spots

More information on how to use the product, like I mentioned above my questions on what one can use after the product

Dark Spot Diminisher works

By James G., St. Louis, MO, Verified Reviewer

The first thing to say is that for me this works - it diminishes dark spots. Would I buy it again? Not sure if I'll continue to need it, but if so then sure, I'll buy it again for the sake of appearance.

The second to say is that the product does not claim to be a dark spot eraser. Haven't seen that product yet. Maybe there's a process at a clinic for that - I have no idea.

As a guy, I would say that I'm not wild about the feminine aroma. It's akin to baby powder in some way. I don't think it's powerful.

Length of Use: Less than 3 months

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

Pros and Cons

It works

A feminine smell

Works ok

By Anna H., Torrance, CA, Verified Reviewer

Product seems to somewhat diminish spots but not as quickly as represented. Spots are still there but lightened. I use the product twice daily. My dark spots appear less prominent but are still there. The product appears to be better than some other products I have used. I thought my spots would disappear slowly but they appear lighter only.

Length of Use: Less than 3 months

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

Pros and Cons

Easy to use

Lightens spots

Price is reasonable

Did not take away spots as represented

Product represented more results

Should only state spots are lightened

Dark Spot Diminisher

By Elena K., Philadelphia, PA, Verified Reviewer

Give it some time. It started to show significant results midway through my second bottle. It works gradually so be sure to take pictures before to truly see the results. Very effective product if you use it as directed daily.

Length of Use: Less than 3 months

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

Pros and Cons


Wanted instant results


Bottle size - more choices

First 3 weeks I saw gradual improvement in many of the spots

By Susanne B., Park City, UT, Verified Reviewer

For the first 3 weeks I saw gradual improvement in many of the spots. At that point, I started using a prescription medication for AK and needed to keep on that for 2 weeks. I will return to using your product now and see if I get better results.

Has potential. As stated above I need more time for a fair in-depth assessment. Given the overall quality of the lotion, I would continue to use it as a moisturizer and protective layer.

Length of Use: Less than 3 months

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