Brand Overview

Good Molecules’ Overnight Exfoliating Treatment has been recently reformulated and earned an upgrade from our team from its previous average, 3-star rating. It no longer contains the drying kind of alcohol, nor sensitizing citrus extracts, making it an impressive chemical exfoliant option.

Housed in an opaque frosted bottle with a dropper dispenser, this fragrance-free exfoliant has a serum texture that’s easy to apply and absorbs quickly, making it appropriate for all skin types. It leaves behind no sticky residue, which helps it work well both over and under other skin care products.

The stars of the show in this formula are the alpha hydroxy acids (AHAs) glycolic and lactic acids, plus beta hydroxy acid (BHA) salicylic acid. While Good Molecules doesn’t reveal the exact percentages of each – it gives a cumulative “blend” number of 10% - judging from their placement in the ingredient list, there’s likely enough of these acids present to improve the look of fine lines and wrinkles, uneven skin tone, and enlarged pores.

Even better, the pH of 3.48 (which is within the optimal range of between 3-4) means this will effectively exfoliate skin as claimed.

There aren’t a lot of other supporting beneficial ingredients included, save for vitamin E and hyaluronic acid, but then again the product’s claims don’t go beyond exfoliation. We do wish there were more skin-soothing ingredients included, as the very best exfoliants include them to offset any potential reactions that might occur. To mitigate this, we recommend using a serum that does have soothing and barrier-repairing ingredients to give your skin a little extra love.

That said, this is a very good chemical exfoliant if that’s all you’re after.

  • Serum texture works well for all skin types.
  • Includes exfoliating glycolic, lactic, and salicylic acids.
  • Formula’s pH is within the optimal range for exfoliation to occur.
  • Fragrance free.
  • Formula would be more impressive with more skin-soothing 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
