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.

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.

    Overall Experience:

    Bought three bottles of this product and used as directed for over 2 months. Sent an email with photos to show it made no difference. Was told to use it for 2 to 3 weeks more. Very convenient as it was then out of warranty and just about out of the product. Do not waste your money as my second email was not replied to and have just written off 220 Australian dollars. Don’t waste your money!

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

    Overall Experience:

    I am 67 years old and have many dark spots for over 30 years. I read this advertisement and was very hopeful, finally a product that works. Well, I have used the cream as directed for 6 weeks now and I have not seen any change in color or appearance. I asked my daughters if they noticed anything different and they said no. I am very disappointed the product did not work for me.

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

  • Did not lighten any of my brown spots

    Overall Experience:

    I ordered 3 bottles of the lightening cream and used 1 and 1/2 bottles applying twice a day for over a month now. I have seen no change at all. I am very unhappy with this product. I was really hoping this would work, since I am 61 years old and have several large brown spots on my face and hands.

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

    Overall Experience:

    Dr. Gundry, you didn't consider the population that can't tolerate scented products. I purchased 3 bottles of the Dark Spot Diminisher. But I have to return them. The Spot Diminisher's scent is so potent! I applied it and right away started getting a headache. So I quickly washed it off and afterward I tried washing the scent out of my washcloth, but it wouldn't wash out. So I had to get another washcloth. PLEASE, PLEASE, Dr. Gundry, make an UNSCENTED Dark Spot Diminisher! (I checked a box below, but since I didn't get a chance to use the product, I really can't say YES or NO as to whether I recommend it to a friend. So I just checked a box that expressed my disappointment.)

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

      Company Response from Gundry MD

      Hello, I want to apologize that the scent of our Dark Spot Diminisher was too potent. We take customer feedback seriously so I'll make sure to pass along this feedback to our Product Development team. In the meanwhile, I'd be happy to refund you fully for your order. Please email me at aria@gundrymd.com and I can get that refund processed for you as soon as possible. Thank you!

  • Don't waste your money

    • Verified Reviewer
    Overall Experience:

    Because Dr. Gundry is a well-known doctor, I bought this product thinking it would work if he was standing behind it. I got a 3-month supply and then a few days later I got another 3-month supply that I didn't order. I called and they took care of the mistake. I've used the product as recommended religiously twice a day for 2+ months on several dark spots on my face and hands. There is not any change whatsoever in the spots...no noticeable fading at all. What a hoax. Don't buy this.

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

      Company Response from Gundry MD

      Pamela, thank you for giving our Dark Spot Diminisher a try! I want to apologize for the reshipment of your order but I'm happy to read this was taken care of. In regards to the other 3 month supply, I'd be happy to issue you a full refund. Please email me at aria@gundrymd.com. Thank you.


  • A little disappointed

    • By Susan R.,
    • Fullerton, CA,
    • Mar 17, 2020
    • Verified Reviewer
    Overall Experience:

    I was so excited and hopeful to try this product as I have tried every cream, serum, and remedy to help lighten my facial age spots. I am 53 years old and like other young people, enjoyed my time in the sun; now I am paying for it. I'm sorry to say after about a 3-week use, I have not noticed any difference. I find it to be a little greasy on my face after I apply it, which is fine at night for sleep; however, under my moisturizer and makeup, makes my face very oily. Your customer service dept is fantastic as I had a billing question and she was very helpful.

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

    • Mar 17, 2020

      Company Response from Gundry MD

In the meanwhile, if you have any other questions or concerns, my email is aria@gundrymd.com. Please don't hesitate to reach out.


  • Darkens not lightens

    Overall Experience:

    I’ve been using this product on my face twice a day for two weeks. My dark spots have actually gotten darker and my skin has developed a slight reddish tone. This is the complete opposite of what I was expecting. Not worth the money. I have had better results with other products. I will either return the product or use it as a moisturizer on another part of my body that I don’t care about.

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