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.

Pros
  • Ingredients show clinical evidence for reducing dark spots
  • Minimal side effects associated with ingredients
  • Positive customer reviews indicate it works for many
Cons
  • Confusing pricing information
  • No ingredients that stand out compared to other dark spot treatments

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.

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.

    I have a dark spot on my face for a long time.

    • Verified Reviewer
    • Length of Use: Less than 3 months
    Overall Experience:

    I have had three medium-sized dark spots on my forehead for years. Since I don't have bangs, they are quite noticeable. I have had deep level chemical peels, and every couple of years, my dermatologist freezes the dark spots with liquid nitrogen but they come back. I've been using the Gundry MD Dark Spot Diminisher now for several weeks, and the spots are almost entirely invisible. This product has worked wonders and I am so pleased.

    Pros and Cons:

    • It works
    • Nice smell
    • Easy to apply
    • No “cons” were specified in this review

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

    • Nov 19, 2020
    • Verified Reviewer
    • Length of Use: Less than 3 months
    Overall Experience:

    I have fair skin with freckles snd now at 66 years of age with decades of living in the California sun, even with faithful sunscreen use, I developed age spots on my face, hands, and legs. With regular twice a day application as recommended, I have noticeable improvement. So much so that my husband ordered a bottle for a large growing age spot on the side of his face and it has also shown improvement in the first month of use.

    Pros and Cons:

    • It works
    • It’s easy
    • The scent is not unpleasant
    • The applicator is messy and should be improved

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

  • Fading into the background

    • By Leslie S.,
    • Cupertino, CA,
    • Nov 6, 2020
    • Verified Reviewer
    • Length of Use: 3–6 months
    Overall Experience:

    Fading away isn't so good in a stage actress, but it's just what I want for those pesky brown spots on the backs of my hands.

    This product has a couple of advantages - once it's dry no one knows you're using anything, and there's no smell. I keep a bottle on my desk and apply a couple of times a day, with no one the wiser.

    Fading isn't fast, but I'm seeing results with consistent use.

    Pros and Cons:

    • Invisible when applied
    • Not sticky
    • No aroma giveaway
    • I wish it worked overnight

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


  • I think I finally found what I have been searching for

    • By Nickole S.,

    • Verified Reviewer
    • Length of Use: Less than 3 months
    Overall Experience:

    I have been using the Dark Spot Diminisher for about 2 months now. I can honestly see a difference. The reason I did not rate it 5 stars is due to my "laziness" I guess you could say. I have not been consistent in my use of the product daily, which is silly on my part. I think my results would be better if I stuck to a daily routine and did not skip days here and there. I am going to continue to use this product regularly. I expect that I will be very more pleased with the results. I will write another review in about a month to share my progress. Thanks!

    Pros and Cons:

    • That it produces results
    • No “cons” were specified in this review

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


  • Love Dark Spot Diminisher

    • By Brenda K.,
    • Carlton, MN,
    • Oct 30, 2020
    • Verified Reviewer
    • Length of Use: Less than 3 months
    Overall Experience:

    It took about 2 weeks before I saw a sunspot diminish. I can barely see it anymore! I am excited to try it on my hands next. I have a couple of spots on them as well. I have noticed my face has a younger, brighter in appearance!

    Pros and Cons:

    • It did what it said, it made the sunspot disappear
    • It is expensive, but worth it

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


  • Actually does what it claims to do!

    • By Becky B.,
    • Minneapolis, MN,
    • Oct 27, 2020
    • Verified Reviewer
    • Length of Use: 3–6 months
    Overall Experience:

    This product is fantastic! I wish I had taken a before pic, but I don't even need that to clearly see how well it's worked! I use it on my face, neck, and decolletage, twice per day. It seems to remove the darker pigmented spots rather than any light-colored freckles.

    I had (keyword "had") an almost black dime-sized spot on my chest that has diminished completely after about 2 months of product use. It actually scabbed over after about 6 weeks, which concerned me a little, but after that, the scab came off, it was lightened and so much smaller, then after a couple more weeks, it was completely gone! Yay! I highly recommend this product!

    Pros and Cons:

    • Easy to use, no scent, and dries quickly
    • It actually works
    • Worth every penny
    • It doesn't seem to remove lighter spots

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