By working directly with labs, Good Molecules offers products that target skin issues—like acne, redness, and hyperpigmentation—without the traditional retail markup (for example, some products start at just $6). In this review, we are going to focus specifically on one of the brand’s most popular products: Good Molecules Discoloration Correcting Serum. We’ll discuss the key ingredients, how to use this serum, Good Molecules Discoloration Correcting Serum reviews from real customers, and more.

Is Good Molecules Skincare Worth The Money?

A common question about this brand is if the products are worth the cost.

In our opinion, Good Molecules products deliver value for money, but take a look at other brands that don’t require you to sacrifice your precious money.

We recommend brands that are committed to developing clean yet effective products.

One brand is Carrot & Stick, a clean skincare brand that perfectly balances the gentle nurturing of plants with the powerful results of innovative science.

Carrot & Stick intro bundles deliver great value for money because you can bundle 3 full-size products worth up to $240 for $88.

What is Good Molecules Discoloration Correcting Serum?

Good Molecules Discoloration Correcting Serum is a lightweight serum that is said to improve the appearance of age spots, acne scars, hyperpigmentation, and sun damage. It is a treatment serum that can be used both morning and night before your normal moisturizer.

What Are The Key Good Molecules Discoloration Correcting Serum Ingredients?

There are two key ingredients in Good Molecules Discoloration Correcting Serum: 4% niacinamide and 2% cetyl tranexamate mesylate. In this section, we’ll dive deep into the science behind how these ingredients affect your skin.

Niacinamide is the amide form of vitamin B3 (niacin) that provides many benefits to the skin. For instance, niacinamide is well known as a potent antioxidant. Antioxidants help the skin combat free radicals, the unstable molecules that contribute to the formation of premature wrinkles and fine lines on the skin. Niacinamide is also a precursor to the coenzymes NADH and NADPH. These coenzymes play an important role in cellular metabolism, which means they provide skin cells with the energy needed to function properly. Lastly, a publication in the Journal of Clinical and Aesthetic Dermatology, states that niacinamide can repair the skin barrier and improve skin moisture, as well as reduce inflammation, blotchiness, hyperpigmentation, acne, and wrinkling.

Cetyl tranexamate mesylate is a relatively new tranexamic acid derivative that may help brighten the skin tone and fade discoloration. Tranexamic acid works by inhibiting plasmin, which means that it helps to break down proteins in the skin that contribute to melanin production. However, the structure of pure tranexamic acid doesn’t permit it to penetrate the skin barrier. That’s why the brand uses cetyl tranexamate mesylate in the Good Molecules Discoloration Correcting Serum.

Cetyl tranexamate mesylate has a similar structure to skin lipids and, therefore, is able to easily penetrate the skin barrier. From there, it provides a steady release of tranexamic acid to deliver better results for preventing and correcting discoloration. In a 2021 study published in the Journal of Cosmetic Dermatology, cetyl tranexamate mesylate was well-tolerated and successfully improved the overall facial skin tone, as well as the appearance of dark spots and redness.

Besides these two key ingredients, the Good Molecules Discoloration Correcting Serum formula is very clean. The formula does not contain fragrance, PEGs, ethoxylated ingredients, mineral oils, or alcohol. Most of the Good Molecules Discoloration Correcting Serum consist of water and humectants, like butylene glycol and glycerin. Humectants slow water from evaporating in the epidermis and, therefore, help to keep the skin hydrated. Humectants also provide temporary anti-aging effects because the extra hydration is extra volume, which effectively plumps out the skin and makes lines and wrinkles less noticeable. However, this effect is transient – as soon as the moisture content in skin decreases, lines and wrinkles will return to normal size.

There are some powerful plant compounds to help address pigmentation, such as Morus Alba Root Extract  and Scutellaria Baicalensis Root Extract. One product we recommend is Carrot & Stick Brightening Spot Treatment.  It contains 2 highly effective plant-based compounds combine to correct the look of hyperpigmentation and uneven skin tone

Good Molecules Discoloration Correcting Serum Reviews

Good Molecules Discoloration Correcting Serum reviews on the brand’s website are mostly positive, with the product receiving an average of 4.3 out of 5 stars at the time of writing this review.

The positive Good Molecules Discoloration Correcting Serum reviews mention that it does help to fade discoloration while also brightening the complexion. For example, one review says, “This serum definitely has an effect on fading my hyperpigmentation. I saw results in the first week. It’s not gonna get rid of them in a week or two, but it seems to me that over time it can fade them drastically. After seeing results from this serum, I bought daily brightening serum as well. I am hoping by using both of them in AM and PM they work even better.”

There are a few reviews from customers with sensitive skin who mention that the Good Molecules Discoloration Correcting Serum is very gentle and doesn’t lead to irritation. For example, one review says, “The discoloration serum has been a great addition to my routine and I’ve been using it for about 3 months. It is gentle on my sensitive, acne-prone skin and I have started to see improvements in the hyperpigmentation and discoloration spots on my face within the first couple months. I have purchased it again.”

However, there are a few negative reviews for the Good Molecules Discoloration Correcting Serum from customers who either didn’t see the results they were hoping for, or they experienced negative reactions after using this product. For example, one reviewer broke out in painful blemishes after using this serum. Her review says, “I tried this product for two weeks. By the third week I had to call it quits. I broke out in deep, painful, cyst-like pimples in odd places on my face where I have never had acne before (tip of the nose, bottom of the chin, cheek bone/temple area). The other troubling side effect was skin felt like it was burning any time I got sweaty from a workout. It has been about a week since I stopped using it and luckily the deep pimples have been diminishing. However, my skin is now more discolored than before.”
