Brand Overview

Good Molecules’ Hyaluronic Acid Serum isn’t a bad product by any stretch of the imagination… it’s just one that’s hard to get excited about considering how lackluster its formula is compared to similar products. The price is tempting but honestly you’re not getting much for your money.

Like most of Good Molecules’ products, this fragrance-free serum comes in a frosted glass bottle with a dropper dispenser. Normally we’d say that the packaging requires this to be stored away from direct light (antioxidants and some other skin-beneficial ingredients can break down in the presence of light), but this doesn’t have any light-sensitive ingredients, so that’s not an issue here.

But that’s not necessarily a good thing: Other than sodium hyaluronate (the salt form of hyaluronic acid, which is fourth from the bottom ingredient-wise, unlike comparable hyaluronic acid serums from The Ordinary and derma e that feature it much  more prominently) there isn’t a lot going on here in terms of other skin-beneficial ingredients.

There are some moisturizing ingredients and texture enhancers here – which is nice, since this has a serum-like texture that isn’t sticky and doesn’t pill like some other hyaluronic acid products – but that’s about it. Contrary to Good Molecules claims, this isn’t doesn’t provide skin with “deep hydration”.

The best serums and boosters feature much more powerful formulas, so even though this doesn’t have anything bad in it, its bare bones formula doesn’t make it a must-have, either.

  • Contains skin-plumping sodium hyaluronate.
  • Isn’t sticky at dry-down like some other hyaluronic acid products.
  • Fragrance free.
  • The star ingredient, hyaluronic acid, is not front and center in this formula.
  • Would be more impressive with additional beneficial ingredients.
Jar Packaging: No
Tested on animals: 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
