Brand Overview

Good Molecules’ Daily Brightening Serum isn’t the most robust skin-brightening product on the market, but it has what it takes to get the job done.

Housed in a frosted bottle with a dropper dispenser, it’s best to store this out of direct light, since daylight can still get through the frosted finish (which can begin to break down the main skin tone-improving ingredient, arbutin). This fragrance-free serum has a lightweight texture that absorbs quickly into skin and doesn’t pill or interfere with other skin care products.

As far as the claims that this can promote a bright, even skin tone, Good Molecules is right on the money. It contains an effective amount of arbutin, an ingredient research shows can improve the appearance of dark spots. Arbutin works by breaking down into hydroquinone, long considered the gold standard for skin lightening. Because of this, it can be considered a good alternative for those whose skin might be sensitive to pure hydroquinone.

Co-starring with the arbutin are three forms of hyaluronic acid, which help hydrate and plump skin. Both are welcome additions to this formula.

For a product labeled a serum, we’d prefer to see additional supporting ingredients (such as a broad mix of antioxidants), but for the price you’re getting a proven ingredient that will improve skin’s tone, exactly as claimed.

  • Non-sticky serum texture absorbs quickly into skin.
  • Contains a good amount of skin-brightening arbutin.
  • Includes three forms of skin-plumping hyaluronic acid.
  • Fragrance free.
  • Needs to be stored out of direct light to protect some of its ingredients.
  • Formula would be more impressive with additional beneficial ingredients.

Maintain a bright, even-toned complexion with this Daily Brightening Serum from Good Molecules. Beta arbutin and hyaluronic acid go to work to gently brighten and promote a healthy, youthful complexion without irritation. Gently brighten and target dullness with beta arbutin, which works to inhibit excess melanin production for clear, even skin. Hyaluronic acid binds to moisture and draws it into the skin to maintain a healthy moisture balance and protect from dehydration. The lightweight, water-based formula layers seamlessly under skincare and makeup, making it ideal for daily use.

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
