Gundry MD Dark Spot Diminisher
( 45 reviews )

Polyphenol Dark Spot Diminisher by Gundry MD is a skincare product which the company states uses a proprietary polyphenol extract formula to minimize the appearance of dark spots on the skin.

There are a number of factors that lead to the formation of dark spots and other blemishes on the skin.  The most common is from prolonged exposure to harmful UV rays from the sun.

However, recent research is revealing that there are also a number of everyday environmental factors that can lead to the degradation of our skin’s appearance.

This results in many people looking for treatments and serums to achieve more healthy and youthful looking skin.

Below we take a closer look at Gundry MD's Polyphenol Dark Spot Remover claims, ingredients, and effectiveness.

How Does It Work?

The Gundry MD website states that the Polyphenol Dark Spot Diminisher is an advanced serum designed to address the age spots, sun spots, and liver spots that give skin a blotchy, uneven tone.

They state that their formula was specifically chosen to fade the appearance of these dark spots by using polyphenol extracts, which some studies have found can be beneficial in protecting skin from sun damage.

Polyphenols provide many benefits to the body, these plant compounds are full of antioxidants and can help aid the body with digestion, cardiovascular health, cancer protection, osteoporosis, and diabetes.

Antioxidants, and specifically polyphenolic antioxidants, can help the body fight free radicals, protecting against oxidative stress to the cells.

You can increase your intake through a healthy diet that includes high sources of polyphenol rich foods such as dark berries, certain herbs and spices, cocoa powder, nuts, flax seeds, vegetables, and olives. 

Dr. Gundry’s company also markets a Polyphenol-Rich Olive Oil specifically for this purpose.

Dark Spot Diminisher Ingredients

The Gundry MD website provides potential customers with a full list of the included ingredients.  They highlight the following as key ingredients in Polyphenol Dark Spot Diminisher:

  • Blueberry Fruit Extract/ Acai Fruit Extract/Sweetesse Arctic Meadowsweet Extract/Superox-C -  These fruit extracts are the source of the polyphenol, vitamin C, and the additional vitamin content of this serum.

  • Brightenyl - This trademarked formulation of Glycerin (and) Aqua (and) Diglucosyl gallic acid was developed specifically to brighten skin, even out skin tone, and reduce red pigmentation. 

    Some research has shown that it was effective in achieving these results.

    Diglucosyl gallic acid can be found in other skin brightening, dark spot correctors, and anti-aging serums.
  • Granpowder Lumiere-DP - Diamond powder is a unique ingredient that has been growing in popularity in high end skincare products.  

    It’s used for its exfoliating properties and its supposed ability to reflect light over the skin diminishing the appearance of wrinkles and evening out skin tone.
Additional Ingredients

It’s interesting to note that some of the key ingredients singled out on the Gundry MD website appear further down the ingredient list, meaning that they're found in smaller amounts than those listed ahead of them.

The ingredients listed higher up the list include more common humectants (moisturizing agents), exfoliants, skin conditioners and so on.

One ingredient that stands out is the use of Bacillus Ferment - this enzymatic exfoliant is a milder alternative to alpha-hydroxy fruit acids.  It helps stimulate the skin’s natural exfoliation process by speeding up the shedding of dead skin cells.

Potential Side Effects

Gundry Md states that these ingredients are 100% natural and safe, and have all been tested for safety, quality, and purity at an independent, 3rd-party facility.

First time users with concerns about how their skin will react to a new product should do a patch test before beginning regular use. 

The website also recommends that patients take a “before” picture before they begin using the product.  This way they will be able to have a comparison for how the product is working for them over time.

Even though the Polyphenol Dark Spot Diminisher is a milder alternative, those with extra sensitive skin may experience some negative responses to bacillus ferment.

Another potential irritant for those with highly sensitive skin or allergies is the use of Parfum (fragrance) in this product.  

On Reviewopedia there are some complaints from users who found the scent overpowering and had to stop using the cream as a result.

Currently a single bottle of Dark Spot Diminisher is priced at $120, but customers have the option to purchase this product in larger volumes in order to get a discount off the per bottle price.

  • One Bottle: $120

Online Customer Reviews & Complaints

You can find many positive reviews for the Dark Spot Diminisher serum.  Lots of customers have stated that it worked as advertised and they experienced an improved complexion.  

You can also find some before and after photos posted by users on their website.

While the overall ratings are positive there are some detractors for whom the product did not work.  These users mentioned that they saw no difference in their skin’s appearance and didn't notice any reduction in their dark spots.

As a company, Gundry MD has an A+ rating with the BBB and their customer service team appears to make an effort in replying to most online complaints.

Competitors and Alternatives?

While there are many skin care formulations on the market the most similar to this would have to be Beverly Hills MD Deep Wrinkle Filler.  

While focusing more on wrinkles instead of dark spots the two creams share a lot of key ingredients such as Diglucosyl gallic Acid and diamond powder.  They retail at similar price points.

Gundry MD has a whole line of different supplements, all intended to boost your overall health and wellness, including PrebioThrive, and Vital Reds.

Customers who are looking for other supplements with high levels of polyphenols will want to speak to their local health food store about what options may be available.

The Bottom Line

Overall, the Gundry MD Dark Spot Diminisher has positive reviews, comes with a solid money back guarantee, and is sold from a company in business for over 8 years.  

Even though there are some negative customer reviews out there, the larger proportion of positive customer reviews may be enough reasons to give it a try.

Skin conditions and responses are highly personalized so you may want to compare some of the key ingredients in this formula to ones you’ve used in the past for a better idea of how this product will affect you.

It’s also important to take preventative measures with your skincare, mainly concerning sun protection.

Product Expiration

Bought 2 bottles years ago. Indeed, it diminished the dark spot as promised in the ad. My question: I Still have left overs of the 2nd bottle, does this product expire?

Dark Spot Corrector
March 30, 2022

I have tried various products to lessen my dark spots including expensive treatments, without success.

I have been using the dark spot corrector faithfully twice a day for a month and I believe I am actually seeing a noticeable reduction in appearance. I look forward to the upcoming weeks.

What Dark Spots!
March 28, 2022
I have loved the Dark Spot Diminisher. My spots have drastically reduced in two months, and my skin is notably younger-looking. I wish I had found this gem three years ago. I have already referred this to many friends and family members. GREAT JOB, Dr. Gundry.

Making a difference
March 27, 2022
I have been using this product morning and night for 1 month and can definitely see a difference. Will continue to use it.

This product works.
March 26, 2022
I love this product. Not only are my dark spots going away, but my skin is looking younger, especially on my hands, which always looked older than the skin on my face. My hands are silky smooth and I am please with the results so far.

Worth every penny!
March 25, 2022
I've purchased many products and this has given me the best results. I am 70 years old and have been told often that I look like I'm in my late 50's or 60. This stuff is amazing, add the firming cream and it's like a fountain of youth.

Amazing results where I thought I had no hope at my age!
March 24, 2022

I am almost 75 and began getting a lot of very embarrassing dark spots on my hands and forearms a couple of years ago. Doctors shrugged about it like it was normal but my hands were obviously ugly.

I saw Dr. Gundry’s ad, read the entire advertisement and with the the awesome guarantee decided to try it. I wish I had taken a before and after picture because I am no longer embarrassed!

He says up front it takes persistence and I was determined to truly give it a good try which payed off for me and has made me more than pleased.

It smells good

My face looks more even and I don’t have as much acne

Really works
March 14, 2022
Have to say that I was skeptical but I have experienced noticeable improvement in my complexion using the Dark Spot Diminisher. While all of my dark spots aren't gone yet, after 3 weeks I believe that all my spots have lightened and some are gone.

Dark spot removal work for me
March 13, 2022
A Dark spot appeared on my forehead overnight, I’ve appointment with my local Dermatologist to investigate, however, using dark spot removal and some other facial cleansers the spot is now barely visible. I’m glad I took a picture of it , because I would like to know what cause the inflammation on the skin.

March 8, 2022

I am finishing my first bottle. I am pleased with the firmness and fresh look of my skin and hopeful that I will soon be clear of my dark spots.

Really truly works.
February 27, 2022

I have used Polyphenol Dark Spot Diminisher for around 3-4 years now.

I am 65 years old with fair to light medium skin tone with so very much non sunscreened sun exposure to my face and arms and legs.

My worst darkest spot on my face has lightened quite a bit and 3 other darkened areas on my face and some on my neck and chest were prevented from getting darker and larger and have evened up to my regular skin tone. It is a nice serum texture and mixes well with everything else I’ve used it in conjunction with, from cleansers to toners, other serums, moisturizers and primers.

I don’t ever want to be without Polyphenol Dark Spot Diminisher again.

I DO wish it were cheaper as my income will be shrinking when I retire next year from special education work at an elementary school.

Confidence Level is 100%
July 9, 2020
I'm absolutely 100% satisfied, I have used expensive products in the past and none have treated my dark spots on my face until I found the dark spot diminisher from Dr. Gundry. It will leave your face feeling hydraded, feeling really smooth and smelling good. Thank you Dr. Gundry for this miracle serum!!!! I'm also a big fan of your vital red and blues. I'm recovering from a broken kneecap and I feel that I'm healing faster with these products. My physical therapist would approve of my testimony also my confidence level is at its highest not having to hide my face because dark spots. Thank you so much for your brilliant inventions. I apply the serum after showering.

6 weeks later - Dark Spot Diminisher review
May 6, 2020

It has been 6 weeks of usage 2x a day to both sides of face. I took photo before and after and there is small difference but not visible without the photograph. Maybe another 10-15 weeks of usage?

I wanted this Dark Spot Diminisher to work so I can purchase more to use on neck and shoulders but it is too costly.

The DSD does have very pleasant smells (my significant't other thinks I am getting ready to meet someone) and I like the consistency of the liquid.

I agree with Ann that a roll on applicator would be preferred than a dropper.

coupons offered are not aacceptted
April 7, 2020
I was going to order this product. Online they have codes and coupons available. But when I tried to use it at check out it said no longer accepting discounts. That seemed like false advertising to me so I did not order.

March 31, 2020

I have seen a diminishing of the bigger patches that are on the sides of my face. Are we supposed to scrub off the scaly (brown) skin that is appearing?

I find that the tiny little spots of dark spots are not improving as well.

I did find that a red, patchy keratosis appeared on my cheek and as soon as I applied this serum, faithfully, for a few days, it is now gone!!

Improvement in 2 weeks
March 12, 2020
After 2 weeks I see my freckles getting lighter. I'll continue to use this expect the freckles to be almost invisible. I'm very please with the results.

Dark Spot Remover seems to work.
March 6, 2020

It seems to work. My wife noticed that my skin looks better and I thought so too.

I think it has definitely lightened the dark spots. They are not gone but lighter. That is fine with me.

Still waiting for results...
February 15, 2020

It's been about a month but I have yet to see results. I realize that the applications must be done twice a day (morning and night) and I think I may have forgotten a few applications, but for the most part, I have been using the product daily. I like the smell and feel of the serum on my skin. I avoid making it go on my lips as I apply it on my face because I noticed the first week that the top part of my lip was dry and crusted. It was a weird feeling.

Also, I do not like the bottle with the dropper cap. I find that the serum tends to drip down and gather at the top which wastes the product and makes it messy. I would prefer a squirt dispenser.

Boverman Jennifer February 17, 2020

I agree about the bottle. If you don't put the dropper exactly in the middle as you return it into the bottle, the sides of the dropper scrape off product on the top of the bottle and then it drips down, gets messy in the lid etc. not only does it make a mess, you're correct about losing product. What I'm trying to do now is after I take the dropper out, I drop the product into my palm then wipe the sides of the dropper before returning it to the bottle.

LauraFabiani February 18, 2020

That's a great idea, Jennifer. Thanks for sharing.

Ann April 06, 2020

I think a roll on applicator would work and allow for less waste.

TerriWilson March 09, 2022

I agree that a roll-on applicator would be much easier to use, as well as save product.

Brown spots are slowly fading
February 14, 2020
The product worked great on two of my dark spots within a few weeks. I can’t even see them anymore. Unfortunately it’s been a real slow process for the rest of my spots. I’ve been using the product for about 6 weeks. I’m not sure why they aren’t going away. Keeping my fingers crossed! I know it can work!
