Brand Overview

Good Molecules’ Super Peptide Serum sounds like a potent anti-aging powerhouse, but despite containing some good peptides, it’s not quite as impressive as it seems.

Like most of the brand’s products, this is packaged in a frosted bottle with a dropper dispenser. Normally that would be a concern if a skin care product contained light-sensitive ingredients, but such good ingredients are absent here, including the peptides, as none have a fatty acid base that would make them prone to rancidity with ongoing light exposure.

The texture of this product is water-light and non-sticky; it absorbs quickly into skin. There are three peptides included: acetyl hexapeptide-8, acetyl octapeptide-3, and copper tripeptide-1. Among them, the copper tripeptide-1 has the most research pertaining to its ability to firm skin, reduce roughness, smooth wrinkles, and more.

That isn’t to say the other peptides aren’t worthwhile; both have some ability to act as skin-restoring and water-binding ingredients (and that’s good for skin’s overhaul health). In essence, you’re getting a pretty good mix of peptides for your money; there are better peptide products to be found, but most of those cost quite a bit more.

The single issue that keeps this from earning a better rating is the small amount of fragrant bergamot oil. Even though it’s near the end of the ingredient list, it still puts skin at risk for irritation, especially since this doesn't have additional calming or soothing ingredients to serve as a buffer to that effect. Instead of choosing this, we recommend selecting another peptide-infused product from our list of best serums and boosters.

  • Water-light formula absorbs quickly into skin.
  • Peptides included, especially copper tripeptide, have proven anti-aging benefits for skin.
  • Contains a small amount of fragrant bergamot oil, which can irritate skin.

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
