Brand Overview

Good Molecules’s Vitamin C Booster Powder boasts the power of one of skin care’s gold-star brightening ingredients, but its benefit is largely undone by a poor packaging choice.

This product is straightforward and simple to use: housed in a plastic jar (with a scoop included) is the powder of one form of vitamin C: l-ascorbic acid.  Years of research show that l-ascorbic acid is effective in treating many of the signs of aging, including an uneven skin tone, dark spots, and diminishing all types of wrinkles.

The instructions say to use one scoop of powder and add it to your favorite serum or moisturizer, where it dissolves quickly to create an extra “boost” of vitamin C in your favorite skin care products. This does dissolve and works well in other products (though you should not mix it, or any other booster product, directly into sunscreen as it can effect its ability to protect you from UV rays).

One issue with this product is that it’s one-note – while vitamin C is amazing, it’s best accompanied by other ingredients to complement its benefits, and since l-ascorbic acid in particular may cause some sensitivity, it would be nice to see some soothing ingredients such as licorice or allantoin alongside it.

The other problem is that this comes in a jar. Even in powder form vitamin C is vulnerable to oxidizing when it comes into contact with air – which this jar readily allows. See More Info for details on why jar packaging for this kind of product is a bad idea.

While they avoid problematic ingredients such as fragrance, this effective but still disappointing product winds up falling behind the superior offerings you’ll find on our list of best vitamin C products.

Pros:
  • Vitamin C (l-ascorbic acid) has years of research proving its benefit to skin.
  • Powder mixes well in both serums and moisturizers.
Cons:
  • One-note formula would be more impressive with additional beneficial ingredients.
  • Packaged in a jar, meaning its star ingredient isn’t protected from light and air.

More Info:

Jar Packaging & Beneficial Ingredients: Beneficial anti-aging ingredients, which include all plant extracts, almost all vitamins, antioxidants, and other state-of-the-art ingredients, are unstable, which means they begin to break down in the presence of air. Once a jar is opened and lets air in, these important ingredients begin to deteriorate, becoming less and less effective. Routine exposure to daylight also is problematic for these ingredients.

Jar packaging is also unsanitary because you dip your fingers into the jar with each use, contaminating the product. This stresses the preservative system, leading to further deterioration of the beneficial ingredients.

Remember: The ingredients that provide the most benefit in addressing visible signs of aging must be in airtight or air-restrictive packaging to remain effective throughout usage. Buying products in this type of packaging means that the ingredients have the best chance of remaining effective—to the benefit of your 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 https://www.beautylish.com/b/good-molecules.
