Good Molecules Discoloration Correcting Serum Review



The Story Behind Good Molecules

Good Molecules was founded by a team of beauty industry veterans at Beautylish. Their philosophy is to provide skin care that works at a fair price. 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.

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.

How to Use Good Molecules Discoloration Correcting Serum

Apply a few drops of the Good Molecules Discoloration Correcting Serum in the morning and at night before oils and moisturizers. It is suitable for daily use.
