Brand Overview

Good Molecules’ Discoloration Correcting Serum is another strong brightening product in their lineup; we just wish it had a little more going for it.

Like most of the brand’s products, this comes in a frosted bottle with a dropper dispenser. Because this type of packaging isn’t completely opaque, we recommend storing this in a dark place so it’s out of direct light that can degrade some of its beneficial ingredients.

Texture-wise, Good Molecules gets it right – this is a lightweight serum that doesn’t feel sticky or tacky, and works well both over and under other skin care products. It’s also fragrance free.

Niacinamide is one of the ingredients responsible for supporting this product’s claims of being able to help with discolorations. Also known as vitamin B3, niacinamide has numerous topical benefits, including evening skin tone, diminishing enlarged pores, and improving fine lines and wrinkles.

Giving it a boost is tranexamic acid, a synthetic amino acid. Some comparative studies have shown that in concentrations of 3% or more, it’s as effective as gold standard hydroquinone in fading skin discolorations (though hydroquinone has years more research behind it). Good Molecules doesn’t list the percentage of tranexamic acid used, but it's good to see it alongside niacinamide to give it a boost.

Also included are three forms of skin-plumping hyaluronic acid to hydrate skin. As with its sister product, Daily Brightening Serum, this doesn’t have much more going on other than its star ingredients, but for the price you’re getting effective ingredients without any bad stuff, which we’re always happy to see!

  • Contains a good amount of skin-brightening niacinamide.
  • Includes three forms of skin-plumping hyaluronic acid.
  • Fragrance free.
  • Needs to be stored out of direct light to protect some of its beneficial ingredients.
  • Formula would be more impressive with additional beneficial ingredients.
Jar Packaging: No

Good Molecules is the house skin care brand of online retailer Beautylish. Beautylish got its start in 2010 in San Francisco and features articles on makeup and skin care topics, community reviews and feedback, and of course sells beauty products from a variety of brands.

Good Molecules launched in 2019 because the team behind Beautylish wanted to create a skin care company that focused on effective ingredients with a bargain price, not unlike the line’s most direct competitor, The Ordinary, which Beautylish also sells.

To that end, Good Molecules focuses on a small core of booster and treatment-like products, some being notably better than others. Just like The Ordinary, some of the formulas are one-note (focusing on a single ingredient or a pair of ingredients, instead of offering a more well-rounded option). This isn’t what research has shown is best for skin any more than eating only one healthy food would be a wise dietary choice; however, at these prices, some of these one-note products can make a nice addition to a great skin care routine.

Another concern is that almost all of the packaging is in bottles that need to be stored out of light to protect their ingredients. And we’re not thrilled that one or two products include citrus ingredients known to be irritating and the drying type of alcohol. Unlike many of the options from The Ordinary, however, the textures of the Good Molecules products are generally quite nice and layer well.

Still, the line’s philosophy is solid and there are some worthy entries, as long as you keep your expectations realistic (a single ingredient isn’t the solution to any skin concern). For more information about Good Molecules, visit
